Accidents caused by brake checking in Arizona can lead to serious injuries, vehicle damage, and disputes over fault. Brake checking occurs when a driver suddenly slams on the brakes or slows down aggressively to intimidate, warn, or retaliate against another driver who is following too closely.
While rear-end collisions often create a presumption that the trailing driver was at fault, brake checking can complicate liability and may contribute to an accident.
What Is Brake Checking?
Brake checking is when a driver intentionally slams on the brakes or slows down suddenly to force the vehicle behind them to react. Drivers may do this because they believe another person is following too closely, feel angry, or want to punish another motorist.
This behavior is dangerous, especially at highway speeds. A sudden stop can give the driver behind too little time to react, leading to a rear-end crash or multi-vehicle collision.
Is Brake Checking Illegal in Arizona?
Arizona does not have a statute that specifically uses the phrase “brake checking.” However, brake checking may violate traffic laws depending on the circumstances.
A driver who intentionally brakes without a legitimate reason may be cited for:
- Reckless driving
- Aggressive driving
- Unsafe vehicle operation
- Other traffic violations
Whether brake checking is illegal often depends on the driver’s conduct and the facts of the incident.
Why Brake Checking Is Dangerous
A vehicle traveling behind another vehicle has limited time to react when the lead driver brakes suddenly.
Brake checking can result in:
- Rear-end collisions
- Multi-vehicle crashes
- Loss of vehicle control
- Chain-reaction accidents
- Serious injuries
The risk increases when traffic is heavy or speeds are high.
Who Is at Fault in a Brake Checking Accident?
Fault in a brake checking accident depends on the specific facts of the crash. Although the driver who rear-ends another vehicle is often found at least partly responsible because drivers are expected to maintain a safe following distance, that is not always the end of the analysis.
If the lead driver intentionally brake checked another vehicle, drove aggressively, created an unnecessary hazard, or otherwise acted recklessly, they may also share responsibility for the car accident. Investigators, insurance companies, and courts often examine the actions of both drivers before determining fault.
How Does Comparative Negligence Affect a Brake Checking Claim?
Arizona follows a pure comparative negligence system. This means more than one driver can share responsibility for an accident. For example, the driver behind may be partially at fault for following too closely, while the lead driver may also share fault if they intentionally brake checked another vehicle or acted aggressively.
If you are found partially responsible for the crash, you may still recover compensation. However, your recovery could be reduced by your percentage of fault. Because insurance companies often try to shift blame after brake checking accidents, gathering strong evidence is important to protecting your claim.
Evidence Used in Brake Checking Cases
Proving brake checking can be challenging because the conduct occurs quickly.
Evidence may include:
- Dash camera footage
- Traffic camera footage
- Witness statements
- Vehicle event data recorder information
- Police reports
- Accident reconstruction analysis
Video evidence is often particularly important in these cases.
Common Injuries in Brake Checking Accidents
Sudden collisions can cause a wide range of injuries.
Common injuries include:
- Whiplash
- Neck injuries
- Back injuries
- Concussions
- Broken bones
- Traumatic brain injuries
The severity often depends on vehicle speed and the force of impact.
How Drivers Can Reduce the Risk of Brake Checking Accidents
Aggressive driving behaviors often increase the likelihood of collisions.
Helpful safety practices include:
- Maintaining a safe following distance
- Avoiding confrontations with other drivers
- Remaining calm in traffic
- Allowing aggressive drivers space
- Following traffic laws
These habits can reduce the risk of accidents caused by road rage or unsafe driving.
