A driver will not receive a moving violation for driving through a yellow light in California. The vehicle must have entered the intersection before the light turned red to avoid a citation. Drivers in California may make right-hand turns on red when applicable. California is one of 41 states that allow left-hand turns on red lights if both streets are one way. The state’s red-light rules and possible fines aim to encourage drivers to come to full stops at red lights and stop signs to prevent intersection collisions.
