Chapter 4Right-of-Way
Section § 21800
When you're driving up to an intersection, you need to let any car already in the intersection from a different road go first. If you and another car arrive at an intersection from different roads at the same time, give way if you're on the left and the other car is on your right. However, if your road doesn't continue through the intersection, let the car on the road that does go ahead.
If stop signs are at all corners, the car on the left should still yield to the one on the right. If the traffic lights aren't working, stop first, then proceed carefully, again giving way to any car on your right, unless it's a terminating road. Some rules don’t apply if there's a working signal, a yield sign, or if cars face stop signs from fewer than all directions. Also, the rules don't apply if you're facing a car making or about to make a left turn from the opposite direction.
Section § 21801
This law states that if you're driving and want to turn left or make a U-turn on a road, you must let cars coming from the opposite direction go first if they're close enough to be dangerous. You have to wait until it's safe before you turn.
Once you've let those cars pass and you've signaled your intention to turn, you can make your turn, and then the other cars must let you go.
Section § 21802
If you're driving and come to a stop sign at an intersection, you must stop and let any traffic that is either coming towards you or so close that it's dangerous go first. Once it's safe, you can enter the intersection, and other drivers must then let you go. However, if every road leading to the intersection has a stop sign, this rule doesn't apply.
Section § 21803
If you're driving and come to an intersection with a yield sign, you must give the right of way to vehicles already in the intersection or close enough to be a danger. Keep yielding until it's safe for you to go.
Once you have safely yielded and decide to move into the intersection, other drivers coming towards you must give you the right of way, allowing you to drive through safely.
Section § 21804
If you're driving onto a highway from a driveway, alley, or any type of property, you must let all the oncoming traffic go first if they're close enough to be a danger. Keep waiting until it’s safe to move.
Once you've yielded and it's safe to go, other drivers on the highway need to let you enter or cross.
Section § 21805
This law allows the Department of Transportation and local authorities to mark certain highway intersections as equestrian crossings by installing signs. These signs will alert drivers to the crossing and the need for any additional safety measures.
When a horseback rider is crossing at these marked areas, drivers must yield to them. However, horseback riders must also take care to ensure their own safety, and they should not suddenly move into the path of a vehicle that poses an immediate risk.
Section § 21806
If an emergency vehicle with flashing red lights and a siren is approaching, other drivers must pull over to the right edge of the road and stop until it passes, unless directed otherwise by a traffic officer. Drivers in special lanes need to safely exit those lanes. Street car operators need to stop and wait too. Pedestrians on the road should head to the curb and stay put until the emergency vehicle has gone by.
Section § 21807
This law section states that even if an emergency vehicle driver is allowed certain privileges on the road, they must still drive carefully and ensure the safety of everyone else on the road and surrounding property.
Section § 21809
If you're driving on a highway in California and see a stationary emergency vehicle, tow truck, or Department of Transportation vehicle displaying flashing lights, you must be cautious. You should either change to a lane not right next to the vehicle if it's safe and legal, or, if you can't, slow down to a safe speed considering the conditions around you.
If you don't follow these rules, you might face a fine of up to $50. However, these rules don't apply if the vehicle isn't next to the highway or if there's a physical barrier separating it from traffic.
