The NYT Wheels Blog reports:

Laws banning cellphone use while driving apparently haven’t reduced crashes, according to a study released on Friday that compared the number of total crashes before the ban with the number after. The study found virtually no difference in the numbers, a finding that had the researchers scratching their heads.

“We were very surprised,” said Adrian Lund, the president of the Highway Loss Data Institute that conducted the study and an affiliate of the Insurance Institute for Highway Safety.

The thought was, of course that if law were passed that decreased cellphone use, then there should be fewer crashes. But that was not the case.

“You know that there should be fewer,” he said. “We were looking for that, and we aren’t seeing that pattern,” said Mr. Lund, who is also the insurance institute’s president.

Any guesses as to the likelihood that jurisdictions will repeal their bans in light of the evidence that they don’t work?

      Somewhere between a fat chance and a slim chance.

      Perhaps, the people who were distracted by their cellphone use are now distracted by something else. Maybe, we should ban driving by people who are distracted.

      So is that because people are ignoring the law? or does obeying the law makes no difference?
      Answer number one seems likely which means that more rigorous enforcement would be the next logical step.

      Maybe because cell phone use while driving is just a subset of a larger problem of people doing other things while driving. Someone who thinks that talking on the phone is OK, is going to think eating while driving, staring at billboards, changing tunes on their stereo, etc., is OK.

      Perhaps my locality is very different from the four studied, but here, in Chicago, my own experience is that I see no decline, marked or otherwise, in the use of cell phones following the (unenforced) ban on their use here. When I’m out walking, in about every third car that goes by the driver is chattering away. And when I’m behind someone who is driving without regard to the timing of traffic lights, the flow of traffic, the idea of signalling, the existence of lanes, etc., they invariably are on the phone. No doubt they’re calling in to say they’ll be late, but we are all late — because they and the other talkers are driving so poorly. (Admittedly, they are not the only ones: breakfast eaters, makeup appliers, blackberry typers, and worse are all out there). But no one I’ve asked has ever been ticketed for cell phone use, or knows of anyone who has been.

      Personally, I would repeal nothing based on this study.

      Right. The logical solution is to ban open containers of any beverage (including water), food, and stereos from the driver-accessible portion of the car.

      And we need a “sterile cabin” rule where no unnecessary discussion occurs in the cabin of the car when the vehicle is in motion.

      Similarly “cabin voice recorders” and “vehicle data recorders” should be mandated on all vehicles and should be routinely investigated after every incident.

      We should try to make driving as safe as commercial air travel....

      I doubt any jurisdiction will repeal their laws (well, a state or large city — maybe it is a different story if we’re talking about a small township, etc.). The fines bring in revenue. “Safety” was probably just a convenient excuse for many politicians in the first place.

      I’m not surprised by these results at all.

    9. Alast says:

      Lack of enforcement, and distraction substitution. People who insist on incessant cell phone use are the same ones who work hard to fill any “idle” time with multitasking. They simply substitute another (distracting) task to accompany the “idle” time driving.

    10. Laura Victoria says:

      I doubt most jurisdictions who passed these laws really care that much, they just have to appear to be doing something. Thus 40,000 new laws were passed in the US that went into effect January 1.

      They won’t be repealed because they can now be used as probable cause to pull someone over so cops can see what else might shake out of that driver’s tree.

      My view is that all forms of distractions that impair driving should be treated equally — including DUI, whose propensitiy to cause accidents is allegedly equal to use of cell phones and dwarfs in comparison to texting. Of course, reaching down to the floor of your car to pick up something you dropped there, turning around to scold your kids or dog, eating, and cell phone talking don’t carry the same puritanical opprobrium as intoxicating oneself, thus seriously injuring someone while scolding kids will likely carry only civil liability, and a DUI involving no accident where the driver was stopped a block from his home. After all, the former case was “just an accident.”

      Isn’t the call for repeal premature? 

      Some quotes from the article:

      One reason Mr. Lund was so surprised was that the institute had previously conducted research that showed that drivers talking on cellphones seemed to be four times as likely to crash.

      “We still don’t think we understand this fully,” said Mr. Lund.

      Another possibility for the surprising finding is that drivers in places with these bans may be switching to hands-free phones. In this case, crashes wouldn’t decrease because the risk is about the same as with handset phones, Mr. Lund said.

      In other words, at this point, “the eveidence that they don’t work” is pretty slim.

      Look for other sorts of bans. Like proximity switches in cell phones that will disable the phone when close to a car.

      Next up: Sensory deprivation pods for passengers and shackles to keep the driver’s hands on the wheel so there are absolutely NO distractions.

      Better yet, why not just ban automobiles? Then there would be no automobile crashes.

      Yeah, that’s the ticket.

    14. Off Kilter says:

      I thought previous research in the economics literature demonstrated similar findings regarding speed limits, lap belts, and other efforts to make driving safer. People, it seems, achieve what they consider an “optimum” level of safety, and it is NOT “zero chance of accident.” There are trade offs. So laws that make driving safer are responded to by, for example, driving faster or paying less attention. One economics wag said if you want to make driving safer, just mandate sharp spears extend from the driving column...

      Just as a note, the sarcastic response I made wasn’t entirely without precedent. Indeed it is mostly an adaptation of commercial air traffic rules to the environment of a single-driver car with no separation between the driver compartment and the passenger compartment. At the same time, I am fairly sure that such rules as I have proposed would make our roads less safe, rather than more safe.

      However, I would note that there is an obvious reason for the findings according to the researchers: if the hands-free risk is the same as a normal usage risk (which I find probable), then mandates to use only hands-free head technologies wouldn’t affect things at all. However, nobody is willing to put up with a total ban on cell phone usage so we are going to see the old ineffective compromises which provide no public benefit and reduce liberty continue.

      driving angry is at least as bad if not worse than driving drunk. absolutely the worst and most driving I’ve observed has been people with hot tempers. It is possible to drive first and talk on the phone second, and it is possible to talk on the phone first and drive second.

    17. yankee says:

      I’m surprised the researchers are surprised. I thought it was already well-established that restricting drivers to handsfree phones doesn’t reduce accidents. The increased risk from talking on the phone while driving comes from distraction, not from having a hand taken up, but states have only banned using handheld phones.

      As for Orin’s question, I would put the chance of repealing the headset laws at somewhere between minuscule and infinitesimal. The chance that states will actually ban cell phone use while driving (which would be very annoying but might actually be effective) is even smaller.

      Some commenters have asked about enforcement: if you look at the NYT post, it says the researchers did observational studies at street corners and exit ramps. They found that hand-held cellphone use dropped from 41 to 76 percent after the headset laws were passed.

      Don’t know that I’d consider “Collision claims per 100 insured vehicle years for new vehicles” for, at largest, about a two-year time-slice after the ban dates, to be much of a measure of anything. Why new vehicles only? 

      Crim law mayvens and deterrence advocates: on average, when something is newly criminalized, or when sentencing for an offense is substantially increased, what’s the normal lag before the offense rate declines?

      More interesting was the pretty-close-to-perfect match in the changes in claims rates (presumably seasonal/weather driven) between “ban” and “non-ban” compared jurisdictions (presumably otherwise comparable), without any particular information, or even speculation, as to the reason for the discrepancy in the actual claim rates: CT seems to be 10–20% lower than NY/MA, before and after the ban, except at the high spikes; CA seems to be roughly 10% higher than NV, both before and after the ban....

      If you’re referring to the tort law system, it doesn’t work well for this purpose, due to displaced responsibility from the third-party automobile insurance system and because of underclaiming. (Although I believe the latter isn’t as significant a phenomenon in the automobile accident context as it is in other contexts, like medical malpractice.)

      These statistics show that a significant percentage of deaths on the highway are related to alcohol consumption. Are there similar statistics related to cell phone use that I could not find? If what you advocate (similar punishment for all “distractions”) is true, then the punishment for cell phone use should be the same as for DUI or is your position that one should ignore the results of drinking and driving? /snark off

      Drunk driving is not a distraction, it is a dangerous state which lasts (usually) the entire time you are driving. It is not the equivalent of talking on the phone, even if you talked the entire time you were on the road. In addition, in a study that I did on our four and five time DUI patients at Vanderbilt many years ago (an internal study, never published) the average DUI occurred about one in every 250 times that a person drank to excess and drove indicating that those who drink and drive do it a lot. 

      The statistics mentioned show a decline in the overall percentage of highway deaths related to alcohol and a trend towards fewer highway deaths overall. I suspect that has a lot to do with enforcement of the laws and increasingly worsening penalties. 

      On the other hand, I suspect that the evidence relating cell phone use and deaths is not very rigorous. Texting on the other hand ...

      I can’t believe that everyone, including the researchers, are missing the obvious: accidents caused by cell phone distraction are a tiny minority of accidents. Even eliminating them all together wouldn’t be seen in the statistical “noise”.

      (The same thing has happened in the commercial trucking industry. Texting causes atrociously bad driving. But that doesn’t lead to many actual accidents. That’s why the researchers opened up their analysis to “dangerous behaviors” such as lane departures or speeding. Given the size of commercial trucks, I’m still in favor of that ban, but the statistics aren’t as clear as is being claimed.)

      If it was the “hand held” part of cell phone usage that was dangerous, why haven’t we also banned holding a cup of coffee or a bottle of water while driving? In point of fact, the “hand held” part of cell phone usage has absolutely nothing to do with why they are dangerous (who drives with two hands anyway?).

      The danger of cell phones–as anyone who has driven behind someone who is yakking on their phone likely knows–is that the driver is distracted by having a conversation with someone who is outside the vehicle. So it is not surprising that the laws in question didn’t show any positive results, as they aren’t aimed at the right problem.

      Amen to Keith who nailed it early. If tough new DUI penalties had not decreased the traffic fatalities caused by drunken drivers two years after going into effect, should we just declare that DUI penalties don’t work, and give up?

      I’m all for the idea that DUI is just one form of impairment, and distraction (e.g. by cell phone) is another, and all impaired drivers should be punished equally. But one problem with that mode is necessary conferral of incredible levels of discretion and authority to traffic cops. Another is that insurance companies or tort plaintiffs will have to argue about esoteric topics like the “degree to which a driver was impaired” by reading a text message vs. pressing buttons to send a text message vs. having a beer vs. having 8 whiskeys. 

      It doesn’t seem unreasonable to just propose a simple, bright-line rule that cell phone use while driving is not OK. The cops’ decisions to give out tickets for driving will be a tad less arbitrary and juries will have the easier task of deciding whether someone was talking on their phone (or not), instead of trying to assess some kind of net impairment level that cell phone use caused in particular situation.

      And if accident rates don’t improve immediately after such a law goes into effect, maybe it is a sign that better enforcement is needed.

      I see a lot of cops talking on the cell phone while driving.

      At least on my ridealong a couple of years ago, it’s worse than that. They are talking on the cell phone, the radio, and typing on the data terminal, frequently all at the same time. Oh, and scanning outside and seeing things I totally missed. I think cops become very, very good at paying attention to multiple things at once. It also doesn’t hurt that traffic is usually very well behaved in the vicinity of a marked car.

    42. Matthew Carberry says:

      Alcohol is tracked in accidents because it is mandatory for the police to do so and there is no way to hide one’s BAC. However, its presence at any given arbitrary level in any given person doesn’t necessarily mean it was the cause of, or even the largest contributing factor to, the accident. Unless the supposition is that drivers above the legal limit are the only drivers without any other distractions going on.

      As we learn more about distracted driving and the habits of neglectful drivers we may well find that the effects of alcohol (while real) may have been overstated due to the moral issues involved.

      Laws don’t work purely through fear of punishment. For example, no one litters or doesn’t litter based upon fear of getting a ticket. If talking while cell phoning develops the same social stigma as drunk driving, then accidents will decrease. Laws that penalize this activity play a vital role in developing this stigma.

      Humans tend to over-estimate their ability to overcome impairment. Drunks drivers think they’ll never be in an accident, and ditto for cell phone drivers. If you want to decrease accidents, you need to convince people to not drive drunk because driving drunk is intrinsically wrong... otherwise, they’ll just assume that they won’t get in an accident until they kill someone. When your son or daughter is killed by a cell phone driver, I doubt you’ll be satisfied by the enhanced penalties... you would have preferred that they never cell phone drove in the first place.

      There are a lot of people out there whose livelihood depends on being accessible (on call, etc). This expectation is one thing that drives cell phone use in general and also while driving. It is also entirely why it is impossible to fully ban its use in cars.

      However, there is a second major problem that generally gets unaccounted for. I am sure that switching tunes on the radio is something that causes a fair number of crashes out there, as is eating and drinking (non-impairing beverages, like coffee or water) while driving. However, if you have ever done much long-distance driving, these sort of things also prevent highway hypnosis and may actually prevent more accidents than they cause.

      So even if driving while talking on the phone increases the risk of an accident during the duration of the call, it isn’t clear that it creates a net increase in accident risks.

      Imagine driving 1200 miles in a day without listening to the radio, engaging in no unnecessary conversation, not drinking coffee while driving, etc. Would this be more safe or less?

      I time my driving to avoid rush hours near major cities and also lessen the hazards by driving mostly at night, when the Interstates are largely clear of congestion.

      There are a lot of people out there whose livelihood depends on being accessible (on call, etc).This expectation is one thing that drives cell phone use in general and also while driving.It is also entirely why it is impossible to fully ban its use in cars.However, there is a second major problem that generally gets unaccounted for.I am sure that switching tunes on the radio is something that causes a fair number of crashes out there, as is eating and drinking (non-impairing beverages, like coffee or water) while driving.However, if you have ever done much long-distance driving, these sort of things also prevent highway hypnosis and may actually prevent more accidents than they cause.So even if driving while talking on the phone increases the risk of an accident during the duration of the call, it isn’t clear that it creates a net increase in accident risks.Imagine driving 1200 miles in a day without listening to the radio, engaging in no unnecessary conversation, not drinking coffee while driving, etc.Would this be more safe or less?

      There is no evidence that listening to the radio increases the risk of accident. There is evidence that cell phones do. If you need to kill me or my family for your livelihood, then I’d rather you just do it clean with a bullet to the head rather than through the painful maiming of a car accident.

Oh, and scanning outside and seeing things I totally missed. I think cops become very, very good at paying attention to multiple things at once. It also doesn’t hurt that traffic is usually very well behaved in the vicinity of a marked car. 

      The worst driver I have ever seen was weaving back and forth from one lane to the other, hit the snow on the right side then into the opposite lane. He did this several times while I was behind him. Of course I backed way off but I followed him several blocks, but only because he was going the same way I was. I would have called the police to report him, but he was driving a police car. I really doubt he was much aware of what was going on in the vicinity outside his car.

      I bet having screaming kids in the car has caused more than one accident. Ban them too?

      Also I have heard plenty of anecdotes of accidents occuring when changing tapes/cd’s/radio stations. While listening may not be risky, things that happen to make listening possible may be. While the plural of anecdotes is not data, it does suggest that the distraction involved in setting up the radio the way you want it creates a potential for an accident.

      Also, I wonder if foreign language courses (via tape or cd) which have a talkback component are as distracting as cell phone usage.....

      Right, my understanding is that “macro-level” analysis such as looking at number of crashes by state or by time of day when people are most likely to be talking on the phone shows no effect. On the other hand, if you put people inside a driving simulator their performance noticeably worsens when talking on a cell phone (including hands-free device). Maybe one reason is that in a simulator there is no real risk to crashing. Interestingly, talking to a fellow passenger does not appreciably increase the risk of an accident — this may be because fellow passengers are likely to alert the driver if there is a danger on the road. On the other hand, insurance actuaries with access to data on individual crashes insist talking on the phone is a definite risk factor for a crash.

Everyone, from the CEO of Goldman Sachs to the Solicitor General, to . . . you and me, has a “boss” or bosses, clients or customers.

      I’ve lived in chicago for the past 3.5 years and i didn’t even know there was a ban on cellphones while driving.

      anecdotally, i just spent a few months in california which i know was very vocal about their ban. despite this, cellphone usage was nearly identical to that before i moved some 4 years ago. it may even have increased because i saw a lot of people with bluetooth headsets...but i couldn’t tell if they were actively using them or just didn’t remove them from their ear from an earlier call.

      so i would say, from my experience, is that lack of enforcement and knowledge of the laws is the main reason why there is no change in accidents since before the bans.

      Actually, this might be true. The author of Traffic states that roads that are planned to be safe have far more accidents than roads that are deemed ‘unsafe’ by traffic engineers. It’s because when you are driving and you think that the road is safe, you are more careless in your attention, whereas unsafe roads (or driving conditions) make you more alert.

      You and a passenger are having a conversation. As you accelerate down the onramp to the

      Secondly, conversations while driving tend to be a bit desultory — you’re talking to pass the time, not conduct business (IMHE; there are of course exceptions). Some phone conversations may also be to pass the time, but to the extent people are trying to conduct actual business, I would expect the phone conversation to command more of your attention budget than a pass-the-time conversation about the Dodgers.

      My personal theory (that I haven’t been able to prove) is that people talking on the phone in the car are caring too much about not being rude to the person on the other end of the phone. They insist on paying attention to what the other person says and not asking them to repeat themselves, and the sometimes spotty reception that cell phones have cause people to pay even more attention.

      Meanwhile, if a person is in a car next to me, we still can use body language (even if I’m not looking at them) to convey information, and it is easier to listen. And if something deserving attention happens on the road in front of us, the person sitting next to me is not going to insist on talking through it. They will stop talking, or understand if I stop talking.

      It might be that the social pressure against phoning while driving makes driving worse, because people who are driving are trying to pretend that they are not.

      Maybe. However, unnecessary conversation between a pilot and copilot has been judged to be the cause of more than one major airplane crash. Is there anything which makes a car better in this regard? I doubt it. In fact, I can think of all kinds of reasons why it should be less of a problem in an airplane, starting with the fact that the copilot can step in and control the plane if necessary. And indeed, there was a near crash a few years ago at Logan Airport where two ATC’s gave two planes runway clearance on intersecting runways, where the quick thinking of the copilot saved the day.

      1) Listening to a REALLY INTERESTING and engrossing talk radio program

      pot meet kettle: why? not the cellphone part, but why do you think driving drunk is “instrinsically wrong”? 

      Part of the disconnect comes from the imprecision of the terms. I doubt anyone would argue you are negligent and morally culpable if you drive when you are actually functionally impaired, that’s what people think of when they hear “driving drunk”, but functional impairment is testable state, usually recognizeable by breaking one or more existing traffic laws and confirmable by failing an actual physical field test. 

      BAC’s, however handy they are as a “quick and dirty suggestion of impairment, are designed around averages and don’t take into account personal tolerance. There are folks who will pass any cognitive or reaction-based test you can think of at higher than .08 (or even .10). Yet they are subject to arrest and conviction based on that subjective number if stopped at a “safety checkpoint” even if they have not violated, and are statistically no more likely than an utterly alcohol-free person to violate, any actual driving-related traffic regulation.

      Further, the neo-prohibitionists’ emotionally-driven modern moral crusade against the demon rum has long since run off the path of reasonable good intentions and led to such nonsensical (and ascientific) statements as “if you drink (implicit any amount of alcohol), don’t drive”.

      Enforce existing driving-related traffic laws vigorously and test for impairment (not arbitrary BAC, actual field test impairment) as necessary after establishing real PC for a stop . Then if we want to punish the voluntarily chemically impaired or negligently distracted (reading, makeup, texting/phone use), more severely, go ahead.

I don’t think one can or should ignore a study just because it doesn’t fit with one’s preconceptions, but at the same time, when it clashes with common sense, one should cast a skeptical eye. These studies were not controlled studies of actual cell phone use on actual roads — how could they be? — but in artificial settings. No doubt that cell phone use can be a distraction which can affect reaction time, but unlike drunkenness, you can choose to stop talking on a cell phone when you need to concentrate on your driving.
