According to California law, parents are required to have their child in a car seat when using taxis and rideshares. Taxis themselves typically do not carry car seats for passengers. To ensure compliance with the law and the safety of your child, it's recommended that you bring your own car seat when traveling with young children in taxis.

A practical approach to meeting this requirement is to either bring your own car seat or arrange for transportation services in advance that provide car seats. Some services, such as Airport Taxi Cab Services, offer the convenience of pre-booking and providing car seats for passengers. This way, you can have peace of mind knowing that your child will be safely accommodated during the ride.
