Key Takeaways:
California Cracks Down on Speeding with Automated Enforcement and Conditional Limits
- State law now enforces automated speed cameras in high‑risk zones (like school areas and the Pacific Coast Highway) with no warnings issued before tickets are sent.
- Updated rules set 25 mph speed limits in business and residential areas, with school zone limits dropping to 15 mph in some spots; fines can reach $1,000 for passing stopped school buses with flashing lights.
- Drivers are also required to adjust speed in bad weather or heavy traffic – driving either too fast or too slow can result in citations.
New Safety Rules for Distracted Driving, Parking, and Autonomous Vehicles
- The no‑touch law now bans any physical handling of mobile devices while driving – permitting only mounted, hands‑free usage via voice commands, with escalating fines for repeated offenses.
- California’s “daylighting” law prohibits parking within 20 feet of crosswalks (or 15 feet with curb extensions), aiming to boost visibility for pedestrians and cyclists; some fines, such as in San Diego, have been reported at approximately $117.
- Under AB 1777, autonomous vehicle manufacturers may receive compliance notices for violations committed by their vehicles – even if no human driver is present.
Tougher DUI and Teen Driver Regulations Aim to Improve Road Safety
- Repeat DUI offenders now face longer license suspensions and mandatory ignition interlock devices (IIDs) for 1–4 years, depending on offense severity.
- New teen driving restrictions require:
- 50 hours of supervised driving (with at least 10 night hours),
- Zero passengers under age 20 during the first provisional year unless a licensed adult (25+) is present,
- No unsupervised night driving between 11 p.m.–5 a.m.
New Traffic Laws Are Here – And They Could Affect Your Daily Drive in California
Traffic accidents happen far too often on California roads. In 2024 alone, there were more than 39,000 recorded accidents in Los Angeles, resulting in many injuries and fatalities. In response, California is rolling out new traffic laws in 2025, aimed at curbing reckless behavior and saving lives.
One example is AB 1978, which allows authorities to immediately impound vehicles involved in illegal street takeovers, even without arresting the driver. Changes like this can significantly impact your daily commute, the risk of citations, and your legal responsibility in the event of a crash.
This guide explains both the newest 2025 traffic law updates and the foundational California driving laws that continue to shape liability in accident cases. RMD Law helps injury victims when others violate these rules and cause harm.
Core California Traffic Laws Still in Effect in 2025–2026
While new rules are rolling out, many long-standing California traffic laws still apply to every driver. Understanding these foundational rules is just as important as knowing what’s new.
1. The Basic Speed Law (Vehicle Code § 22350)
California’s Basic Speed Law requires drivers to operate at a speed that is reasonable and prudent for current road, traffic, and weather conditions — even if driving below the posted limit. You can receive a ticket for driving too fast or too slow if it disrupts traffic flow or creates danger.
2. DUI Blood Alcohol Limits (Vehicle Code §§ 23152–23153)
- 0.08% BAC for most drivers
- 0.04% BAC for commercial drivers
- 0.01% BAC for drivers under 21
Driving under the influence can result in license suspension, fines, mandatory DUI school, ignition interlock requirements, and even jail time — especially if injuries are involved.
3. Hands-Free Phone Law (Vehicle Code § 23123.5)
Drivers may only use mounted devices in hands-free mode. Holding or physically manipulating a phone while driving is prohibited.
4. Seat Belt Requirements (Vehicle Code § 27315)
All drivers and passengers must wear seat belts. Children under 8 must be secured in appropriate child restraint systems.
5. Right-of-Way Rules at Intersections (Vehicle Code § 21800)
At uncontrolled intersections, drivers must yield to vehicles on the right. Pedestrians have the right of way in marked and unmarked crosswalks.
These evergreen laws often form the basis of negligence claims in California accident cases.
What Are the Key 2025 California Traffic Law Changes?
The rules below aren’t just technicalities; they could cost you hundreds in fines or jeopardize your case if you’re injured in a crash. Here’s what you need to know:
1. Updated speed limit zones
California is cracking down on speeding, where it poses the biggest risks. For instance, under SB 1297, Malibu will install up to five automated speed cameras in high-risk areas, including school zones and stretches of the Pacific Coast Highway. These cameras will catch and fine speeders – no warnings, no second chances.
California is also enforcing the following speed limits in some places:
- Business or residential areas – The speed limit is 25 mph unless signs indicate otherwise.
- School zones – Slow to 25 mph within 500 feet of a school when children are present. Some zones go as low as 15 mph. Fines can hit $1,000 for passing a school bus with flashing red lights.
- Bad weather or heavy traffic – You must drive slower than the limit; too slow or too fast can both result in a citation.
This requirement stems from California’s Basic Speed Law (Vehicle Code § 22350), which gives officers discretion to cite drivers whose speed is unsafe for existing conditions — even if below the posted limit.
2. Stricter distracted driving laws
According to California Vehicle Code Section 23123.5, with this “no touch” law, you can only use your phone if it’s hands-free, such as with voice commands or on speakerphone. If you’re caught using your phone while driving for the first time, the fine is $20. For each subsequent time, the fine increases to $50.
Also, the law explicitly bans the use of smartwatches and engaging in video calls while driving.
3. New fines for blocking bike lanes and crosswalks
California’s “Daylighting” law prohibits parking within 20 feet of any marked or unmarked crosswalk and 15 feet of a crosswalk with a curb extension. This new rule aims to increase visibility at intersections and lower the risk of accidents involving pedestrians and cyclists.
Violating these parking restrictions can result in fines. In San Diego, drivers have faced penalties of $117 for parking violations under the new daylighting law.
4. Harsher penalties for repeat DUI offenders
If you’ve had more than one DUI, brace yourself. California’s 2025 DUI laws hit repeat offenders harder by mandating longer license suspensions and requiring ignition interlock devices (IIDs) for one to four years, depending on the number and severity of offenses.
These breathalyzer devices prevent your car from starting if you’ve been drinking, and courts strictly monitor compliance. This tough approach aligns with California’s Vision Zero goals to minimize traffic deaths and serious injuries by keeping impaired drivers off the road and making streets safer for everyone.
Additionally, DUI convictions can result in:
- 2–4 DMV points
- Increased insurance premiums for 3–5 years
- Mandatory DUI education programs
- Possible felony charges if injuries or deaths occur
Repeat offenses significantly increase jail exposure and probation periods under California law.
5. Expanded rules on autonomous or assisted driving vehicles
California requires manufacturers to meet stringent safety milestones before deploying driverless cars. Plus, even with AI features like lane assist or autopilot engaged, drivers remain responsible for safe operation and must be ready to take control at any moment.
Assembly Bill 1777 allows law enforcement officers to issue “notices of autonomous vehicle non-compliance” to companies operating autonomous vehicles when their vehicles violate traffic laws. It includes infractions such as running red lights or obstructing traffic.
6. New teen driver restrictions
California now requires teens to complete 50 supervised driving hours, including 10 hours at night, before obtaining a provisional license. For the first year, teen drivers can’t carry passengers under 20 years old, unless a licensed adult who is 25 years old or older is present. Night driving between 11 p.m. and 5 a.m. is also off-limits without adult supervision.
7. Pedestrian right-of-way clarifications
Vehicle Code section 21950 requires drivers to yield to pedestrians crossing within any crosswalk at intersections. This law emphasizes that pedestrians have the right of way, and you must stop to allow them to cross safely.
Starting March 1, California authorities began issuing fines for violations of the daylighting law. San Francisco has even implemented red-painted curbs to indicate no-parking zones near crosswalks.
Drivers must also stop for school buses displaying flashing red lights, unless separated by a divided highway. Violations can result in fines up to $1,000 and possible license suspension. At four-way stops, the first vehicle to stop proceeds first. If two vehicles stop simultaneously, the vehicle on the right has the right of way.
8. Statewide camera enforcement for speed and red lights
California is testing traffic cameras in cities such as San Francisco and Malibu to catch speeders and red-light runners. Initially, they send warnings, followed by fines of up to $500. The goal is to make roads safer, particularly in areas near schools and busy intersections.
You’re more likely to get caught without a police officer nearby. Expect stricter enforcement soon, so drive carefully to avoid a ticket from these cameras.
9. Changes to commercial or rideshare vehicle rules
The state now requires rideshare drivers to be at least 25 years old due to rising insurance costs, which raises the bar for new Uber and Lyft drivers. Delivery services must also provide customers with the driver’s ID details, thereby boosting transparency and safety.
What Do These New Rules Mean for California Drivers?
While new California traffic laws may feel stricter, they’re meant to make every drive safer and more predictable. Here’s what you can expect when you’re out on the road.
1. Expect lower speed limits in more areas
More school zones, neighborhoods, and intersections now have lower limits. Miss a sign or fail to adjust, and you’re at risk of a citation. If you hit someone while speeding, that’s strong evidence of negligence in a civil case.
2. Smart devices are now a bigger legal risk
Your smartwatch is now just as risky as your phone while driving. Courts take distracted driving seriously. If you cause a crash while tapping or glancing at a device – even hands-free – those actions could be used against you in a lawsuit.
3. Camera enforcement is expanding
Forget the days of spotting speed traps or timing yellow lights. Automated cameras don’t blink. If you’re caught spreading or running lights, the citation will be recorded, which can follow you into court if you’re ever involved in a personal injury case.
4. Teen drivers face stricter supervision
If you have a teenage driver in your household, you’ll need to spend more time in the passenger seat. These rules are meant to protect young drivers and others on the road, but they also raise the legal bar for responsibility if your teen causes an accident.
5. Traffic violations can hurt you in an accident claim
If you’re in a crash and you broke one of these new rules, like speeding in a school zone or using your smartwatch, you’ve just made the other party’s case easier. Violating traffic laws can prove negligence, which can weaken your ability to recover damages.
What Happens If You Violate These New California Traffic Laws?
Traffic violations don’t just mean paying a fine. Depending on the offense, you could face:
- Points added to your DMV record
- Increased auto insurance premiums
- License suspension
- Mandatory traffic school
- Court appearances
- Criminal charges for serious offenses
More importantly, violating a traffic law can be used as evidence of negligence in a personal injury lawsuit. If your violation contributed to a crash, it could significantly affect your ability to recover compensation.
