Is Brake-Checking Legal in Pennsylvania?

Posted on 04/03/25

Brake-checking happens when a driver suddenly slams on their brakes. Usually, they do this to scare or send a message to someone who’s driving too close behind them. Some drivers think it’s a fair response to tailgating, but that doesn’t make it safe — or legal.

Brake-checking is not legal in Pennsylvania. It violates the state’s reckless driving laws and can get you tickets, fines, and even criminal charges if you cause an accident.

Tailgating is also against the law; however, responding with a brake-check only makes the situation more dangerous and could leave you legally liable. In this article by our top-rated Reading car accident lawyers at Wilk Law, we go in depth on what brake-checking is, why they do it, and who is liable when an accident occurs because of it.

What Is Brake-Checking?

Brake-checking isn’t just tapping your brakes lightly. To truly brake-check another driver, you would need to deliberately apply your brakes when you don’t actually need to stop, an action that forces the driver behind you to brake suddenly or swerve to avoid hitting you.

Some general indicators of brake-checking include:

  • Braking suddenly with no obstacle or traffic signal ahead
  • Slowing down dramatically for no apparent reason
  • Making repeated, unnecessary stops when being followed closely
  • Looking in the rearview mirror before braking to time it with the following car’s position

This behavior differs considerably from normal defensive driving, where you might brake gradually if needed for legitimate safety reasons.

Why Drivers Brake-Check

None of the motivations for brake-checking justify the risks. However, at Wilk Law Personal Injury & Car Accident Lawyers we see drivers caught brake-checking often do it for the following reasons:

Road Rage and Retaliation

Most brake-checking behavior arises from anger. For instance, a driver may get annoyed at someone following them too closely and decide to “teach them a lesson” by braking suddenly. The idea is simple: The driver doing the checking feels disrespected or endangered and wants to get back at the other driver.

Forcing Tailgaters to Back Off

Some drivers brake-check motorists who follow too closely because they want the tailgater to give them more space. They believe a quick tap of the brakes will frighten the following driver into increasing their distance. This justification is less aggressive but still creates unnecessary danger for both drivers.

Insurance Fraud

Insurance fraud is a more extreme motivation.

“Crash for cash” schemes involve drivers deliberately causing rear-end collisions to file fake insurance claims. Scammers often target commercial vehicles or expensive cars, assuming the drivers have good insurance coverage. Some even disable their brake lights to make their sudden stop completely unexpected.

How can you identify a potential insurance scam? Here are some signs to look for:

  • The other driver insists on calling a specific repair shop or doctor
  • Multiple passengers who weren’t visible before the accident start claiming injuries
  • The driver seems oddly calm or prepared for the accident
  • The crash occurs in an area known for insurance fraud

Knowing the telltale signs is important, as it can tell you when to alert authorities to potential scams.

Penalties and Punishments for Brake-Checking in Pennsylvania

Pennsylvania takes aggressive driving seriously, and brake-checking can result in significant legal penalties under several different categories of law. Here are some of the state’s various penalties for brake-checking:

Traffic Violations

Pennsylvania’s traffic code outlines multiple ways to penalize brake-checking drivers, even if no accident occurs, including:

  • Reckless driving citations and fines of up to $200
  • Points on a driver’s license, which can lead to higher insurance rates or license suspension
  • Aggressive driving penalties and steeper fines, especially in work zones

These traffic violations will remain on your driving record for years and can affect everything from your insurance rates to job opportunities.

Civil Liability

Traffic tickets aren’t the only potential consequence of a violation — brake-checking can also expose you to financial risk through civil liability. You might bear financial responsibility for all injuries and property damage you cause, pay higher insurance premiums after the accident, or even be subject to lawsuits from injured parties.

Civil damages can easily reach tens or hundreds of thousands of dollars, which exceeds what most insurance policies will cover for intentional acts.

Criminal Charges

If your brake-checking causes serious harm, you could face the following repercussions:

  • Vehicular assault charges if others are injured
  • Involuntary manslaughter if any injured party dies
  • Assault with a motor vehicle if prosecutors can prove intent to harm

Criminal charges resulting from brake-checking accidents can have serious negative outcomes, including permanent criminal records and possible incarceration.

Liability and Proving Fault in Brake-Checking Car Accidents

Determining who’s at fault in brake-checking accidents can be complicated. The common assumption is that the rear driver is responsible for rear-end collisions; however, brake-checking creates a reasonable exception.

Evidence Used to Prove Brake-Checking

If you need to prove that someone brake-checked you, the following types of evidence will be most helpful:

  • Dashcam footage showing the sudden, unnecessary braking
  • Witness statements confirming that the driver braked for no apparent reason
  • Evidence of aggressive behavior leading up to the incident
  • Expert analysis of skid marks and vehicle damage
  • Traffic or security camera footage from nearby recording devices
  • Cell phone records indicating that the driver was distracted
  • Social media posts in which the driver admitted to brake-checking

Without strong evidence, brake-checking cases usually become thorny “he said, she said” situations that are hard to resolve.

Shared Fault Claims

Pennsylvania uses a modified comparative negligence system to determine fault in accidents, which means both drivers can share responsibility.

If you’re found to be partially liable for your accident, your eligible compensation will be reduced by your assigned percentage of fault. If you’re found to be more than 51% responsible, you won’t be able to recover damages at all.

Example of Shared Fault

For perspective, here’s how a shared fault situation might play out in Pennsylvania:

Imagine that Driver A is aggressively tailgating Driver B on the highway. Irritated, Driver B purposefully slams on their brakes without any legitimate reason to stop, and a collision results.

In this case, both drivers would likely share fault. Driver B, who was the brake-checker, is assigned 70% of the responsibility for deliberately creating a dangerous situation. However, Driver A, who was the tailgater, is assigned partial fault of 30% for the unsafe following behavior that prompted the incident.

If the accident caused $10,000 or more in losses, Driver A could recover $7,000 from Driver B based on the 70% fault assessment.

Safe Alternatives When Dealing With Tailgaters

When someone is following too closely behind you, you don’t need to slam on your brakes to get them to back off. There are better ways of handling such situations. For instance, you can:

  • Drive at a steady speed and avoid sudden or erratic maneuvers
  • Change lanes when it’s safe to let the tailgater pass
  • Gradually slow down and pull over if necessary
  • Increase your own following distance from the car ahead to give yourself more reaction time
  • Focus on safety rather than getting back at the other driver

Remember that responding to tailgating with brake-checking only makes the road more dangerous for everyone. As such, your primary goal should always be to arrive safely, not to enforce traffic rules on others. Stay calm and avoid engaging with aggressive drivers.

What to Do if Someone Brake-Checks You

Here are some steps you can take if another driver brake-checks you:

  • Do your best to prevent a collision safely if possible
  • If an accident is unavoidable, document the scene with photos and videos
  • Get information from witnesses who saw what happened
  • Contact local authorities — this is especially important if there are injuries
  • Consider installing a dash cam for future protection
  • Consult a car accident lawyer to learn about your legal options

Performing these actions immediately after the incident will help you protect your rights and create a record of what occurred, which can be instrumental if disputes about who was at fault arise later on.

When to Contact a Car Accident Attorney

If you’ve ever wondered, “Is brake-checking legal in Pennsylvania,” you should know that it isn’t. It may therefore be wise to speak with an attorney if you’ve been involved in a brake-checking incident.

You should consider talking to a car accident lawyer such as Tyler Wilk if any of these conditions apply to your situation:

  • You’ve been injured in a brake-checking accident
  • You’re being blamed for an accident caused by brake-checking
  • Your insurance claim has been denied or undervalued
  • The other driver is claiming injuries that seem suspicious

Having reliable legal representation can make a big difference in the outcome of your case, particularly in situations where fault may not be immediately clear to law enforcement or insurance adjusters.
