Rear end collisions are usually assumed to be the fault of the driver who strikes another vehicle from behind. In many cases, that assumption is correct because drivers are required to maintain a safe following distance. However, some crashes happen because the front driver intentionally slams on the brakes to intimidate or punish the driver behind them. This behavior is known as brake checking. When brake checking leads to a collision, liability can become more complicated. A knowledgeable rear end accident lawyer understands that these situations require careful investigation to determine who is legally responsible.
If you were involved in a crash caused by brake checking, it is important to understand how California law evaluates fault in these cases.
What Is Brake Checking?
Brake checking occurs when a driver suddenly slams on the brakes without a valid reason, usually to retaliate against another driver. It is often linked to road rage or aggressive driving, especially when the front driver believes someone is following too closely. This behavior can create dangerous situations, particularly at highway speeds.
Why Brake Checking Is Dangerous
Brake checking can cause serious accidents because it forces the following driver to react instantly. If the trailing driver does not have enough time or space to stop, a rear end collision can occur. At higher speeds, the risk becomes even greater because stopping distances increase significantly. Brake checking can also trigger multi vehicle crashes if traffic behind the vehicles cannot stop in time.
A skilled rear end accident lawyer often sees cases where one driver’s aggressive behavior created a preventable accident.
Does the Rear Driver Always Have Fault?
Although the driver in the rear is often presumed responsible in rear end crashes, this presumption can be challenged when brake checking occurs.
California law requires drivers to operate their vehicles safely and avoid actions that create unnecessary hazards.
Shared Fault in Brake Checking Cases
Many brake checking accidents involve shared responsibility.
For example:
- The rear driver may have been following too closely
- The front driver may have slammed on the brakes intentionally
- Both drivers may have contributed to the unsafe situation
California uses a pure comparative negligence system. This means fault can be divided between multiple parties based on their contribution to the accident.
Evidence That Can Prove Brake Checking
Proving that brake checking occurred can be challenging, but several types of evidence may help establish what happened.
Important evidence may include:
- Dashcam footage
- Traffic camera recordings
- Witness statements
- Police reports
- Vehicle data records
- Accident reconstruction analysis
Injuries Common in Brake Checking Rear End Collisions
Rear end crashes caused by sudden braking often lead to injuries such as:
- Whiplash
- Neck and back injuries
- Concussions
- Herniated discs
- Traumatic brain injuries
Compensation Available After a Brake Checking Accident
If another driver’s negligent or reckless behavior caused the crash, you may be entitled to compensation for:
- Medical expenses
- Future medical treatment
- Lost wages
- Reduced earning capacity
- Pain and suffering
- Property damage
The amount of compensation depends on the severity of the injuries and the evidence establishing fault.
