Understanding California Speed Limits (2025)

California's Basic Speed Law Explained

California traffic laws include the Basic Speed Law, which requires drivers to modify their speed to conditions, even if that means going under the accepted limit. Drivers must operate their vehicles at a “reasonable and prudent” speed, and they must consider weather conditions, traffic, visibility and many other factors.

Maximum Speed Limits by Road Type

Different road types have different speed limits in California. On interstate highways, the maximum can be 65 mph or 70 mph, depending on whether it’s a rural or urban area. The maximum speed allowed on other types of highways is 65 mph on multilane ones and 55 mph on two-lane, undivided highways.

In residential areas, business districts and school zones, 25 mph is the limit. In railway crossings, it’s 15 mph, as it is on highway intersections with limited visibility.

Minimum Speed Limits and Advisory Zones

California speed limits apply to how slowly you can go, too. You can’t impede the normal flow of traffic. Advisory speed zones suggest speed limits for specific types of roads, including those in which you can find curves. These are not enforceable speed limits, however.

How Conditions Affect Legal Speed

According to California traffic laws, the speed at which you must travel is not only set forth by the speed limit. Road and weather conditions impact the limit, as well. If there’s reduced visibility, potholes on the road, numerous curves or narrow roads, traffic issues or the presence of pedestrians, the law requires you to adjust your speed accordingly.

Why Speeding Happens and Its Risks

Speeding can occur as a result of traffic congestion, which requires people to rush to get where they’re going. Reckless and aggressive driving can be factors, too, as can not being aware of the speed limit.

Speeding can result in losing control of the car and causing accidents that lead to catastrophic injuries. Because the vehicle will require a significant stopping distance, crashes are more likely to happen.

Penalties for Speeding in California

In California, you can face a fine and five points on your license. The fine you receive will depend on the exact speed at which you were traveling.

Legal Options After Receiving a Speeding Ticket

You can choose to pay the fine or plead “not guilty” and go to trial. In some instances, you may be able to go to traffic school to avoid getting points on your license.
