California Class C: 25 mph Default, Basic Speed Law, Who Goes First
Handbook speeds the DMV repeats: 25 mph residential, 15 mph alley or blind intersection, 65/55 highway defaults, the Basic Speed Law, and four-way / pedestrian / school-bus right-of-way.
Last reviewed
California’s Class C knowledge test is drawn from the California Driver’s Handbook. The items that fail people who already “know how to drive” are the unposted speed limits and who goes first. This page is that pair. Question counts (36 adult / 46 under 18, 80% pass) are in the DMV test guide. Why the handbook beats any playlist is in handbook first.
Residential default 25
Four-way: first / right
Yield is not optional
Prima facie speeds the DMV repeats
Vehicle Code §22352 and the handbook’s “Laws and Rules of the Road” chapter use these defaults when a sign does not say otherwise:
| Place | Limit |
|---|---|
| Business or residential district | 25 mph |
| School zone while children are outside or crossing, within 500 feet of the school | 25 mph; some zones post 15 |
| Alley | 15 mph |
| Blind intersection or certain uncontrolled railroad crossings | 15 mph |
| Most other highways / freeways | 65 mph is the usual maximum unless posted |
| Two-lane undivided highway, or when towing | 55 mph unless posted |
The Basic Speed Law sits on top: never faster than is safe for weather, traffic, sight distance and the road surface, even under the posted number. That sentence is a test item by itself. Practise the numbers in speed and following distance.
Right-of-way without a lecture
- Four-way stop: first to arrive goes first; if two arrive together, yield to the right.
- Uncontrolled intersection: yield to the vehicle already in the intersection, and to the one on your right if you arrive together.
- Pedestrians in a crosswalk — marked or unmarked at an intersection — have the right-of-way.
- Emergency vehicle with lights and siren: pull to the right and stop.
- School bus with flashing red lights: stop. You may proceed on the other side of a divided or qualifying multi-lane highway; do not invent that exception on an ordinary two-lane road.
Open right-of-way and sharing the road as separate sittings. A mixed quiz hides which half is weak.
Alcohol numbers that are not interchangeable
Adult DUI in California is commonly tested as 0.08%. Drivers under 21 are tested at 0.01%. Implied consent and the DMV’s separate administrative action are in the handbook; do not replace them with another state’s 0.05 warn range. See impaired driving.
A short drill
- Write 25 / 15 / 65 / 55 on a card. If 30 appears, you are answering Texas.
- Do speed-only, then right-of-way-only, in the California Class C bank.
- Read the official California Driver’s Handbook chapters on speed and right-of-way once more the night before.
If this page and the handbook disagree, the handbook wins.
