California Speed Limits

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.
