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.
