School zones and school buses — California Permit Test
School zones and school buses on the California permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The speed limit is 25 mph within 500 feet of a school while children are outside or crossing the street.
A child who steps out gives you about a second, and 25 mph is what makes that second enough.
The speed limit is 25 mph within 500 feet of a school while children are outside or crossing the street.
Some school zones have speed limits as low as 15 mph.
Where the road runs right past the gate, even 25 is more than the crossing can take.
Some school zones may have speed limits as low as 15 mph.
Near schools, look for school safety patrols or crossing guards and obey their directions at all times.
The guard is standing in the road because they can see the children you cannot.
School safety patrols or crossing guards.
Some school buses flash yellow lights when preparing to stop to let children off, warning you to slow down and prepare to stop.
Yellow is your warning that the red is coming, and that children are about to be in the road.
Some school buses flash yellow lights when preparing to stop to let children off the bus.
When a school bus flashes red lights, you must stop from either direction until the children are safely across and the lights stop flashing.
Children cross in front of and behind the bus, where no driver can see them coming.
When the bus flashes red lights (located at the top, front, and back of the bus), you must stop from either direction until the children are safely across the street and the lights stop flashing.
If you fail to stop for a school bus flashing red lights you may be fined up to $1,000 and your driving privilege could be suspended for one year.
The penalty is set at the level of what could have happened rather than what did.
If you fail to stop,
If a school bus is on the other side of a divided or multilane highway with two or more lanes in each direction, you do not need to stop.
Children are not crossing lanes of traffic that wide, so the stop would achieve nothing.
If the school bus is on the other side of a divided or multilane highway (two or more lanes in each direction), you do not need to stop.
On the test
What is the speed limit within 500 feet of a school when children are out?
25 mph. A child who steps out gives you about a second, and 25 mph is what makes that second enough. California Driver’s Handbook, p.50: “The speed limit is 25 mph within 500 feet of a school while children are outside or crossing the street.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
