Uber has raised the minimum age requirement for most new drivers in California to 25. The company says the change is necessary because of the rising costs of commercial auto insurance in the state.

Uber raised the minimum age requirement for most of its new drivers in California to 25 on Thursday under rules the company said are necessary because of the rising costs of commercial auto insurance in the state.

The new rule applies only to drivers signing up to transport passengers with Uber’s ride-hailing platform, and not for those delivering food with Uber Eats. Previously drivers as young as 19 could sign up.
