Several new traffic laws took effect in California on January 1, 2026. Whether you commute daily or drive occasionally, these changes affect how you navigate California roads and the potential consequences of a citation.
1. Lower Speed Limits in School Zones (AB 382)
Cities and counties now have the authority to reduce speed limits in school zones from 25 mph to 20 mph. Local governments can also set limits as low as 15 mph within school zones on roads posted at 30 mph or less.
A school zone is defined as any roadway within 500 feet of school grounds. Local governments have until January 1, 2031 to implement these changes through ordinances. After that date, the speed limit automatically drops from 25 to 20 mph in school zones where proper signage is posted.
2. Highway Speed Limit Reductions (AB 1014)
The California Department of Transportation can now lower speed limits by 5 mph on certain highways, particularly in safety corridors or areas with heavy pedestrian traffic. Law enforcement will issue warning citations for the first 30 days after any speed reduction to give drivers time to adjust.
The law also permits speed limits of 20 or 25 mph on roads where lower speeds are necessary to protect pedestrians.

Check eligibility3. Expanded Move Over Law (AB 390)
California's "slow down and move over" law now covers highway maintenance vehicles and any stopped vehicle displaying flashing hazard lights, cones, or road flares. Drivers approaching these vehicles must change lanes or slow to a safe speed if a lane change is not possible.
Violating this law is an infraction with fines up to $50.
4. Speed Cameras in Construction Work Zones (AB 289)
A new pilot program authorizes Caltrans to deploy speed detection technology in highway construction work zones. The system uses fixed or mobile radar or laser technology to capture license plates of speeding vehicles. Citations are issued to the registered owner.
In construction work zones, speed limits are generally reduced by 10 mph from the posted limit. The base fine for a speeding ticket starts at $35, but penalty assessments and court fees can push the total well above $400.
This is separate from the AB 645 speed camera pilot, which covers city streets in six designated cities. AB 289 applies statewide to Caltrans work zones.
5. Tougher DUI Penalties (AB 1087)
Drivers convicted of causing a death while under the influence now face longer probation periods. Previously, probation for a DUI related death could last one to two years. Under the new law, probation typically lasts three to five years.
Why It Matters
These laws expand the ways California can enforce speed limits and increase the penalties for certain violations. For drivers, awareness is the best protection. Pay attention to posted speed limits, especially in school zones and construction areas, and watch for signage indicating automated enforcement.
