Uber will require its drivers to take at least six hours off after every 12 hours they drive for the ride-hailing company.

In a blog post announcing the policy, Sachin Kansal, director of product management, Uber, said the company looks to reduce drowsy driving. A recent report showed 3 percent of American drivers reported falling asleep behind the wheel in the last two weeks.

“While nearly 60 percent of U.S. drivers use Uber less than 10 hours a week, we want to do our part to help prevent drowsy driving,” wrote Kansal.

Uber will now track drivers on-call and driving time, sending warnings when the 12-hour limit approaches. Drivers who hit the limit will be blocked from using the app for the following six hours.

“This move will strengthen our approach to help keep riders and drivers safe on the road while preserving the flexibility drivers tell us they love,” said Kansal.

“This new feature has tremendous potential to protect not only Uber driver-partners, but also their passengers and, ultimately, all road users,” said Jonathan Adkins, executive director, Governors Highway Safety Association.
