In California, you may never drive faster than is safe for the current road conditions. This is known as the Basic Speed Law. Here’s a table summarizing the maximum speed limits in California.
| Most California highways | 65 mph | Ideal maximum speed. Unless Otherwise Posted |
| Two-lane undivided highway and for vehicles towing trailers. | 55 mph | |
| Business districts or residential area | 25 mph | Unless otherwise posted |
| School zones | 25 mph | Within 500 feet of a school while children are outside or crossing the street. Some school zones may have speed limits as low as 15 mph. |
| Safety zone or Traffic Light | 10 mph | When bus, streetcar, or trolley is stopped |
| Blind intersection | 15 mph | An intersection has no stop signs at any corner |
| Alley | 15 mph | Any road no wider than 25 feet |
| Blind railroad crossing | 15 mph | Within 100 feet of a railroad crossing and you cannot see the tracks for 400 feet in both directions. You may drive faster than 15 mph if the crossing is controlled by gates, a warning signal, or a flagman. |
Please note that this table provides general guidelines, and speed limits can vary depending on specific factors and local regulations. Ensure that you control your speed and reduce it when conditions require. Regardless of the posted speed limit, your speed should depend on:
- The number of vehicles on the road.
- The speed of other vehicles on the road.
- The road surface: smooth, rough, graveled, wet, dry, wide, or narrow.
- Bicyclists or pedestrians on or crossing the road.
- Weather: rain, fog, snow, wind, or dust.
- Traffic congestion: small changes in your driving habits can help reduce congestion. Avoid weaving in and out of freeway lanes.
| Wet Road | Reduce your speed by 5 to 10 mph |
| Packed Snow | Reduce your speed by half |
| Ice | Reduce your speed to no more than 5 mph |
| Cannot see farther than 100 feet | 30 mph or less. |
It’s always important to obey posted speed limit signs and adjust your speed accordingly for the safety of yourself and others on the road. For the most accurate and up-to-date information, refer to local traffic laws and signage or consult the relevant local authorities in the specific area you are interested in.
