The Varying Drivers License Requirements Around the World

Minimum driving ages, the number of passengers young drivers can have with them at any time, the times of day that drivers under the age of 18 can drive…

These all vary depending on where young motorists are driving. They vary, even, across the United States.

For instance, in Maine, motorists under the age of 18 aren’t allowed to have any passengers with them as they drive for the first 180 days after they obtain their licenses. In Alabama, motorists under the age of 18 can have one passenger with them.

And that’s just one example of the differences in driving license requirements from one part of the country to the next. The differences are even more pronounced when comparing one country to another. Minimum driving ages vary widely across the world. While most states in the United States allow youngsters to earn their learner’s permits at the age of 15, many other countries require their residents to be much older before they get behind the wheel of a car.
