Which states have the highest and lowest starting ages for unsupervised driving, though perhaps with limits on time and number of passengers? (My source is the Insurance Institute for Highway Safety.)
New Jersey: 17 years.
1 sets the age below 15 (South Dakota).
5 set it at 15 years to 15 years 6 months.
33 set it at 16.
10 set it at 16 years 1 month to 16 years 6 month.
1 sets it at 17 (New Jersey).
According to Europe.Org, "in most [European Union] countries the minimum age for driving is 18."
