Lesson 13 of 38 · California traffic rules

School zones and school buses 25 mph · flashing red lights

The rule

Near a school, the speed limit is 25 mph while children are outside or crossing, unless another limit is posted: within 500 feet of the school (Handbook), and past a SCHOOL sign while children are going to or leaving school (CVC 22352(b)(2)). Stop for children in a crosswalk. A school bus flashing red lights: stop, from either direction, until the lights stop flashing; not if it is across a divided road or one with two or more lanes each way.

In short

What is the school zone speed limit in California?

25 mph near a school while children are outside or crossing, unless a different limit is posted (CVC 22352(b)(2), Handbook). Some school zones are signed lower.

Why this rule exists

Children are small, quick and hard to see, and those getting off a bus may cross in front of it. A slower speed and a full stop give them the margin.

Step by step on the road

  1. At the school sign, check your speedometer: 25 mph at most while children are outside or crossing.
  2. Look between parked cars and at the ends of the sidewalks for children.
  3. Stop for children in a crosswalk; yellow crosswalks are school crosswalks. Wait until they are all the way across.
  4. Obey the school crossing guards (CVC 2815).
  5. A school bus flashing yellow lights is about to stop: slow down and get ready to stop.
  6. When its red lights flash, stop, from either direction, and stay stopped until the red lights stop flashing.

Common mistakes

  • Keeping the street speed past the school while children are outside.
  • Passing a stopped school bus with flashing red lights.
  • Driving on as soon as the children are across, while the red lights are still flashing.

On the DMV drive test

Passing a school bus that has flashing red lights is a critical driving error (DL 955), which notes that traffic in both directions must stop unless driving on a divided highway. Driving 10 mph over the speed limit is a critical driving error too, and the DL 32 sheet marks your speed on every street section.

Questions people ask

Do you have to stop for a school bus on the other side of the road in California?

On an ordinary two-way road, yes. You need not stop if the bus is on the other side of a divided road or one with two or more lanes each way (CVC 22454(b)).

What do flashing yellow lights on a school bus mean?

The bus is about to stop: slow down and get ready to stop. When the red lights flash, you stop.

Why are some crosswalks yellow in California?

Crosswalks next to a school are painted yellow (CVC 21368). Stop for children crossing there.
