California Traffic Laws & Right-of-Way
⏱ ~3-min readAceMark GuideWhat this topic is really about
On a two-lane undivided road, drivers approaching from both directions must stop when a school bus flashes red lights and extends its stop arm. Drivers often think only those behind the bus must stop, but oncoming traffic must stop too unless a raised median or barrier divides the road.
California permits a right turn on red after coming to a complete stop, provided no 'No Turn on Red' sign is posted and you yield to pedestrians and cross traffic. The idea that it is banned statewide is a common misconception, since the default is that it is allowed unless prohibited.

Traps the examiner sets
- The idea that it is banned statewide is a common misconception, since the default is that it is allowed unless prohibited.
- Assuming three statewide is wrong because the requirement varies by location, and a solo driver cannot use it merely by speeding.
- Assuming priority because you are on the bigger road is a common and dangerous error.
