Parents might not know they're breaking the rules when it comes to getting their kids a ride.
Both Uber and Lyft have policies that say drivers can't give rides to unaccompanied minors. Some will avoid picking up at high schools since it's more likely those customers will be underage.
But it's not always easy to tell the age of the person in your backseat. Several drivers say that there's no time to check IDs, so it's a hard policy to enforce.
One Uber and Lyft driver said that when she refused service to someone who was younger than 18, she got chewed out.
"She was irate and yelled at me," the driver remarked. "She said that she lives in Summerlin and gets rides all the time and no one ever complains."
Uber recently launched a pilot program in three cities allowing minors to travel alone using a family account. If the program proves to be successful, it could expand across the U.S.
