The percentage of teenagers with driver’s licenses has declined recently- in 2010, only 28% of 16-year-olds had a license, compared with 46% in 1983. Experts say a number of factors can explain this trend, including the high price of gas and car insurance. Plus, fewer teens need to be able to drive themselves around, since the rate of unemployment in that age group is high. Finally, why get your own license when you can rely on good old Mom and Dad? More teenagers today are willing to hitch a ride with their parents, and more parents seem happy to help out.
