How to Drive in California: Laws, License Requirements, and Safety Rules
Driving in California means following state traffic laws, carrying required insurance, and making sure the driver and vehicle meet licensing and registration requirements. Rules can differ for visitors, new residents, and teen drivers. This guide explains the essentials, from getting a California license to navigating intersections, highways, and child passenger safety requirements.
Who Can Drive in California?
Drivers generally need a valid license issued by California or another jurisdiction. A license must cover the type of vehicle being driven, and drivers must follow any restrictions printed on it. California residents, out-of-state visitors, and international travelers may have different requirements.
- California residents: A person who becomes a California resident generally must apply for a California driver’s license within 10 days.
- Visitors from another U.S. state: Visitors may generally drive with a valid license from their home state, subject to its restrictions and California traffic laws.
- International visitors: A visitor may generally drive with a valid foreign driver’s license. An International Driving Permit can help translate the license, but it is not a license by itself and should be carried with the original license.
Licensing rules can depend on residency, age, and immigration or visa circumstances. Travelers with unusual circumstances should check current guidance from the California Department of Motor Vehicles (DMV) or consult the relevant licensing authority before driving.
Getting a California Driver’s License
Most first-time applicants must complete a DMV application, provide required identity and residency documents, pass a vision screening and knowledge test, and pay the applicable fee. Applicants may also need to take a behind-the-wheel driving test. The DMV’s document requirements can vary, so checking its official checklist before an appointment can help avoid delays.
Rules for Drivers Under 18
California uses a graduated licensing system for minors. Teen drivers typically begin with an instruction permit and must meet driver education and supervised practice requirements before becoming eligible for a provisional license. For applicants under 18, California generally requires at least six months with an instruction permit, driver education and training, and 50 hours of supervised practice, including 10 hours at night.
Provisional license restrictions generally limit driving during the first 12 months: drivers under 18 may not drive between 11 p.m. and 5 a.m. or transport passengers under 20 unless accompanied by a qualifying California-licensed driver age 25 or older. Exceptions apply in specified circumstances, such as medical or school-related needs, and may require documentation. Because details can depend on age and license status, teen drivers should verify their restrictions with the DMV.
Car Insurance and Vehicle Requirements
California requires drivers and vehicle owners to meet financial responsibility requirements. Most drivers satisfy the requirement by carrying liability insurance. As of January 1, 2026, California’s minimum liability limits are $30,000 for injury or death to one person, $60,000 for injury or death to more than one person in a crash, and $15,000 for property damage. These are often written as 30/60/15 coverage.
Liability insurance pays for covered injuries or property damage the insured driver causes to others, up to policy limits. It does not necessarily pay to repair that driver’s own vehicle. Collision and comprehensive coverage are optional under state law but may be required by a lender or leasing company. Higher liability limits can provide more protection than the state minimum.
Drivers should keep proof of insurance available in the vehicle or accessible electronically. California permits electronic proof of insurance. Driving without required financial responsibility can lead to penalties, and a crash without adequate coverage may create substantial personal costs.
Registration, Plates, and Smog Checks
Vehicles operated on public roads generally must be registered and display valid license plates. A person who becomes a California resident generally has 20 days to register a vehicle in the state. Registration may require an emissions inspection, commonly called a smog check, depending on the vehicle, its location, and applicable exemptions. Requirements and exemptions change over time, so new residents should use the DMV’s current out-of-state vehicle registration guidance.
Before driving, check that the vehicle is in safe working condition. Tires, brakes, lights, mirrors, windshield wipers, and seat belts should function properly. California law also requires drivers to maintain adequate visibility; an obstructed windshield or unsafe vehicle condition can create legal and safety problems.
Important California Traffic Laws
Speed Limits and Safe Driving
Posted speed limits set maximum speeds under suitable conditions, but California’s Basic Speed Law also applies: drivers must not travel faster than is reasonable or safe for current conditions. Rain, fog, traffic, road work, limited visibility, and sharp curves may require a speed below the posted limit. Drivers should slow down and leave extra following distance when roads are wet or congested.
Some California highways have higher limits for certain vehicles, while commercial vehicles and vehicles towing trailers may face lower limits. Signs and vehicle-specific rules control. Speeding in a construction zone can carry increased penalties, and drivers must follow temporary signs and instructions from traffic-control personnel.
Traffic Signals, Turns, and Right of Way
Drivers must obey traffic lights, signs, lane markings, and directions from authorized personnel. A right turn on a steady red light is generally allowed after a complete stop, unless a sign prohibits it. The driver must yield to pedestrians and other traffic with the right of way before turning.
A left turn on red is generally permitted only from a one-way street onto another one-way street, after stopping and yielding, unless a sign prohibits the turn. Drivers must signal before turning or changing lanes when required, check blind spots, and yield to pedestrians in crosswalks. At an intersection without signals, drivers should approach cautiously and follow California’s right-of-way rules rather than assuming another road user will stop.
Seat Belts and Child Passenger Safety
Drivers and passengers are required to wear seat belts. The driver is responsible for ensuring that passengers under 16 are properly restrained. Children under 8 generally must ride in a car seat or booster in the back seat, subject to exceptions in California law. Children under 2 generally must ride in a rear-facing child passenger restraint, unless they weigh at least 40 pounds or are at least 40 inches tall.
Car seats and boosters must be used according to the manufacturer’s instructions and installed in a seat that is appropriate for the child and vehicle. A child who is 8 or older, or at least 4 feet 9 inches tall, may use a seat belt, though a booster can still improve fit. The safest arrangement depends on the child’s size, the restraint’s limits, and the vehicle’s seating options.
Phones, Texting, and Distracted Driving
Drivers may not hold and use a cell phone while driving. California law generally requires adults to use a hands-free device for phone functions, while drivers under 18 are prohibited from using a wireless phone or other electronic wireless communications device while driving, even hands-free, except in an emergency. These restrictions apply when stopped in traffic or at a red light as well as while moving.
Setting navigation before departure, using voice controls, and pulling over safely before handling a device can reduce distraction. Drivers should also avoid activities such as eating, adjusting controls, or reaching for objects when those actions interfere with safe operation.
Alcohol, Drugs, and Impaired Driving
Driving under the influence of alcohol or drugs is illegal. For most adult drivers, a blood alcohol concentration (BAC) of 0.08% or higher is the per se legal limit. Lower limits apply to some drivers, including commercial drivers operating commercial vehicles and drivers under 21. A driver can also be prosecuted for impairment below a numerical limit if alcohol or drugs affect safe driving.
California’s implied consent rules apply to chemical testing after a lawful DUI arrest. Refusing a required test can lead to separate consequences, including license suspension. A designated driver, taxi, rideshare, or public transit is a safer alternative whenever impairment is possible.
Sharing the Road and Using California Highways
Drivers should yield to pedestrians in crosswalks, give cyclists space, and check carefully for motorcycles before changing lanes or turning. California’s three-foot passing law generally requires a driver overtaking a bicycle to leave at least three feet when feasible. If that distance is not possible, the driver must slow down and pass only when it is safe.
When an emergency vehicle approaches with lights or a siren, drivers must yield and move to the right edge of the road when safe, then stop. On a multi-lane road, California’s Move Over, Slow Down law requires drivers approaching certain stationary emergency, tow, and road-service vehicles displaying warning lights to move over when safe or slow down. Drivers should follow posted signs and current law, since requirements can depend on the vehicle and roadway.
Carpool lanes, also called high-occupancy vehicle (HOV) lanes, have posted rules for passenger counts, operating hours, and permitted vehicle types. Some lanes are managed as express lanes and may require a transponder or toll payment. Drivers should read signs before entering and avoid crossing solid double lines where prohibited.
What to Do After a Crash or Traffic Stop
After a crash, stop at the scene, check for injuries, and call 911 when someone is hurt or there is an immediate hazard. California law requires drivers involved in a crash to exchange identifying and insurance information and provide reasonable assistance to anyone injured. A crash involving injury or death must be reported to the DMV within 10 days using the required report if the crash meets the DMV’s reporting criteria, including the applicable property-damage threshold. A police report does not replace a required DMV report.
If a law enforcement officer signals a driver to stop, the driver should pull over safely, remain calm, and follow lawful instructions. Keeping registration, proof of insurance, and license information readily accessible can make the interaction more straightforward. Drivers should avoid sudden movements and ask before reaching for items in the vehicle.

Where to Verify California Driving Rules
Traffic requirements can change, and exceptions may apply to individual situations. The California DMV is the primary source for licensing, permits, registration, and vehicle requirements. The California Highway Patrol provides information about traffic safety and enforcement, while the California Legislative Information website publishes state statutes, including the Vehicle Code. Checking these official sources is especially important before a road trip, a move to California, or a teen driver’s licensing appointment.
