Brake-checking is illegal in California. Drivers who try this dangerous practice to throw a scare into another driver can be held liable when a rear-end collision occurs.
Unfortunately, in most rear-end accidents, it’s the driver in back that’s assumed to be at fault. Proving that a driver in front was brake-checking, almost daring a collision, can be difficult.
It’s why, if you are seriously injured in this type of accident, it’s a good idea to speak to a skilled California car accident lawyer. Maison Law offers an absolutely free case consultation to injured accident victims. It’s a no-risk way to find out what their case may be worth and how to prove a reckless driver in the lead was to blame.
Staying Alert for Brake Checking in California
Brake checking is usually thought of as when drivers in front of other cars keep tapping the brakes to get the rear driver’s attention or to communicate a threat.
It’s often associated with road rage when drivers get upset with a motorist’s behavior. They might pull in front of them and slam the brakes to force the motorist to slow down.
These are a few of the most common reasons that people brake check:
- Road rage to punish or start a confrontation
- Trying to get another driver to stop following so closely
- Trying to stage an accident to commit insurance fraud
In California, there are routine reports of drivers purposely causing rear-end collisions as a part of a scam. As recently as May of 2026, the California Department of Insurance (CDI) reported on 4 Southern California drivers charged with staging collisions to earn insurance money.
The practice put victims in danger of financial damage and physical harm. Drivers should always be aware as they travel. And they should always question how and why a rear-end impact occurred.
California Law and Brake Checking
Brake checking is illegal in our state. It can be classified as reckless driving. California Vehicle Code (CVC) 22109. explains how drivers must never stop or suddenly decrease speed without giving a signal or trying to give a signal to the drivers behind them. The letter of the law is explained on our page about the legality of brake checking in California.
In cases where a drive brake-checks to prevent someone from driving on their bumper. Both drivers could be charged. One driver may get a reckless driving charge, and the other may get a “following too closely” charge under CVC 21703.
Collecting Evidence to Expose a Brake-Checking Motorist
Brake checking can sometimes be hard to prove. An officer with the CHP may have a hard time determining what caused a rear-end accident without having witnessed the crash. Unfortunately, an investigator would usually apply fault to the driver in the rear in most instances.
A skilled lawyer on your side can help you collect evidence, and even accident reconstruction data to show why a rear collision actually took place. Eyewitness testimony can also help.
You can also help build your own case by grabbing some valuable evidence at the scene of your accident.
If you feel strong enough and the scene is secure, try to complete these tasks:
- Give the officers a full account of what you saw just before the accident. Tell them if you saw the motorist repeatedly hitting the brakes. Alert them if the driver was making threatening gestures or signals towards you.
- Take photos of the damage to vehicles. Show any tire markings on the lane. These may demonstrate how many times a driver slammed on the brakes.
- Get witness contact information.
- Check to see if anyone had dash cams rolling at the time. Note if any nearby businesses or homes had surveillance systems that may have caught what happened.
- Don’t approach the other driver if it’s a road rage situation. The officer should provide you with the other driver’s information.
You’ll deliver this evidence to your attorney, and it’ll be combined with your attorney’s own investigative results.
When You May Need a California Car Accident Lawyer’s Help
You could do better with a lawyer’s assistance if your accident involves a serious injury. A serious injury involves much more damage (recovery costs), and that makes car insurance companies withhold support. It’s often up to a lawyer to help you prove the other driver’s fault and then to demand everything you’ll need to make a full recovery.
