Is it illegal to not wear a seatbelt in California?
Yes. Every driver and passenger, in every seat, must wear a seatbelt. California enforces its seatbelt law as a primary offense, so police can pull you over for an unbuckled belt alone. The ticket is $20 base fine (about $162 with fees).

Making it automatic, every drive
A ticket only works when someone is watching. BuckledApp makes the phone itself check: when the car reaches 20 MPH, distracting apps lock and a 2.5-second AI selfie confirms the belt is fastened. Passengers get their apps back as soon as the check passes; drivers stay in Driver Focus until the car stops.
Parents on Safety+ see that each child’s last seatbelt check passed and when, and fleets see it for every driver.
