The following rules generally only apply to public streets, not necessarily private property.1The code usually makes reference to the “highway” which is defined as essentially any public street, Vehicle Code Section 360 They also generally apply to all vehicles, including motorcycles, bicycles, motorized scooters aka “mopeds,” and more (see below for details).

Police can arrest you immediately and take your car away.2CA Veh Code Sec 14602.6

Do I need a license plate on the front and the back of the car?

Yes, California requires two license plates for each car, one on the front, and one on the back.4California Vehicle Code Section 5200

What is the requirement for having car insurance?

You must have liability insurance, which covers the damage you cause to others (you’re not required to have collision or other types, which would cover damage to you or others that isn’t your fault). You also must carry proof of this insurance in your car and show it to a police officer upon request.5Cal Veh Code Sec 16020; 16028

If you fail to do so, you may receive a fine of up to $200+ additional fees, plus your car could be “impounded” (temporarily taken from you).6Cal Vehicle Code Sec 16029

You must give cyclists at least 3 feet of space at all times.7CA Veh. Code Sec. 21760 See more on rules for cyclists.

Most people know that it is illegal to drive without a seatbelt; but you may not know that it is also illegal to drive unless all passengers 16 years of age or over are “properly restrained by a safety belt.” (Note: does NOT apply to taxis)8CA Veh Code Sec. 27315 See here for seatbelt/safety seat rules regarding driving your children.

Am I required to stop for a sobriety checkpoint?

Drivers are required to stop and submit to sobriety checkpoints. If police find you have higher than legal blood-alcohol content, they can impound your car for 30 days. However, they can’t do this if your only offense is failing to hold a valid driver license.9CA Vehicle Code Sec 2814.2

What are the rules on honking?

The only circumstance in which you are allowed to honk is to give a warning “when reasonably necessary to insure safe operation.” In fact, it is REQUIRED in this situation.10CA Vehicle Code Sec. 27001

4. Distracted Driving; Reckless driving; Driving and cell phones

Is it illegal to do “donuts” or other stunts with your car?

If it endangers anyone nearby, then yes, this would be considered reckless driving, and it is illegal.

It is also illegal to create a “sideshow,” which is defined as “an event in which two or more persons block or impede traffic on a highway, for the purpose of performing motor vehicle stunts, motor vehicle speed contests, motor vehicle exhibitions of speed, or reckless driving, for spectators.”21AB3

Is “driving while distracted” actually illegal?

While there is no general “distracted driving” law in California, police often cite people for things like applying makeup or changing clothes while driving based on a law prohibiting unsafe speed for the conditions.22Cal Veh Code Sec 22350; LA Times article on distracted driving  So even if you are driving below the speed limit, you can be cited for distracted driving because it is unsafe to drive at any speed while you are doing these things. The more specific distraction of using your cell phone while driving is covered under its own law (see below).

What exactly are the laws regarding using my phone while driving, such as texting or making calls?

If you are over 18 years old: While driving in California, you may not touch a cell phone, tablet, or other communications device for any reason, except to make a quick swipe or tap, but only when mounted on the dashboard or windshield. The only exception is in an emergency.

If you are under 18, you may NOT use either handheld OR hands free device while driving. The only exception is in an emergency.23CA Vehicle Code Sec. 23123, 23123.5, 23124

Penalty: Although the base penalty for a first violation of driving while using your phone is $20, when administrative fees are added in, it comes to a minimum of $159.24Contra Costa Times on administrative fees

For distracted driving or driving while using a cell phone, is it OK to do these things while stopped at a red light?

No. The law prohibits “operating” a vehicle while doing these things, which includes being stopped at a red light.25People v Nelson, CA Court of Appeal (2011)

Is it illegal to drive recklessly?

Yes, reckless driving is when you drive without regard to the safety of people or property. The punishment is up to 90 days in jail and/or fine of up to $1,000.26Vehicle Code Sec 23103

Will new cars in California come with speed-limiting devices?

A new bill – Senate Bill 961 – proposes that all vehicles sold in California starting in 2027 come with speed governors, which would limit the speed of the car to 10 miles per hour above the speed limit. It is not clear whether it will pass and become law. We will keep you updated.
