Lyft, which has said it wants “100 percent” of the vehicles operating on its platform to be electric by 2030, is offering a new slate of incentives to drivers to get them to ditch their polluting, gas-powered vehicles for ones with zero tailpipe emissions.

Starting today, Lyft drivers in California who use an EV are eligible to receive a bonus of $150 if they complete 50 trips in a week — which translates to an extra $3 per trip. Drivers will need to register their EVs on Lyft’s app before the end of 2023 in order to qualify for the bonus. And they can keep raking in $150 per week until they hit the bonus maximum of $8,100.

Only drivers in California are eligible for the Lyft EV challenge, the company says. As the largest market for EVs in the country, California will serve as a test case for Lyft before it determines whether to expand the incentive to other states.
