Cop Brake Checks Biker: Florida Liability and FHP Policy

The lawsuit over a cop brake-checking a biker stems from a May 2022 incident on Interstate 595 near Davie, Florida, where Florida Highway Patrol Trooper John Vincent Greisheimer, driving an unmarked Dodge Charger, slammed his brakes in front of motorcyclist Caylan James Whelan. Whelan crashed into the back of the cruiser, his GoPro captured the sequence, and he has sued the trooper and FHP for negligence in Broward County. The case is scheduled for trial in April 2025.

What Happened on I-595

Whelan was riding a 2020 Yamaha R3 westbound on I-595, just past the Weston Road exit, when he came up behind an unmarked gray Dodge Charger assigned to FHP’s Davie district.¹ Greisheimer, with FHP since 2014, was behind the wheel.²

The helmet-camera footage shows the trooper tapping his brakes, activating the Charger’s concealed emergency lights, then almost immediately braking hard while swerving left.¹ The motorcycle struck the back of the patrol car. After the crash, Greisheimer can be heard yelling, “Stop tailgating me!”² Whelan was handcuffed at the scene and released without charges.³ He said he was mostly unhurt but reported persistent back pain when sitting for long periods.

Two Versions of the Same Crash

FHP’s incident report put the blame on Whelan. According to the report, Greisheimer saw the motorcycle speeding and weaving through traffic, estimated the bike’s speed at 81 mph as it approached the cruiser, and activated his emergency lights to slow the rider. The report described the braking as an attempt to slow the motorcycle and attributed the collision to the rider’s speed and “slow application of the brakes.”³¹

The video complicates that account. The trooper’s brake lights flare hard moments after the emergency lights come on, and the Charger drifts left at the same time. Whelan’s speedometer is not visible in the footage, so the 81 mph figure cannot be independently verified from the video.¹ FHP said publicly that it was “aware of the incident and continuing to gather information.” No disciplinary action against Greisheimer has been reported.³

The Lawsuit and Where It Stands

Whelan filed suit on September 6, 2023, in Broward County Circuit Court. The case, Caylan James Whelan v. Florida Department of Highway Safety & Motor Vehicles, Florida Highway Patrol, and John Vincent Greisheimer (Case No. CACE-23-018016), is classified as an auto negligence action and assigned to Judge Michael A. Robinson.⁴⁵

Trial is set for April 7, 2025, after an earlier calendar call in January was reset.⁵ The parties reported attempting mediation on March 12, 2025; the filing of a mediation report without a settlement indicates they did not reach an agreement. Whelan’s attorney, Emmanuelle Sarah Betito, has filed motions in limine, including one seeking to keep Whelan’s prior traffic citations out of evidence. The state has asked for additional time on expert discovery. Greisheimer and a Sergeant L.A. Castano are listed as witnesses.⁶

Who Can Be Held Liable Under Florida Law

Suing a state trooper in Florida runs through Florida Statute § 768.28. The state has waived sovereign immunity for torts committed by employees acting within the scope of their duties, but recovery is capped at $200,000 per person and $300,000 per incident. Anything above those caps requires the Florida Legislature to pass a special claims bill.⁷

Before filing, a claimant must send written notice to the agency and to the Department of Financial Services within three years of the incident, then wait out a 180-day investigation period before suing. Individual state employees generally cannot be held personally liable for conduct inside the scope of their employment unless they acted in bad faith, with malicious purpose, or with wanton and willful disregard of safety.⁷ That exception is the hinge for a case like Whelan’s: if a jury treats the braking as a legitimate, if aggressive, enforcement maneuver, liability sits with the agency subject to the cap; if the jury sees deliberate retaliation, personal liability for the trooper comes into play.

One boundary worth noting: Whelan sued under state negligence law, not under 42 U.S.C. § 1983. Federal civil rights doctrine and qualified immunity do not govern this case, and the Florida statutory caps apply instead.

FHP’s Own Policy on Unmarked Stops

FHP Policy 17.19 requires troopers to activate emergency equipment before stopping a violator and tells members to exercise patience and discretion, with specific attention to a motorist’s possible fear of being stopped by someone who isn’t visibly a uniformed officer. If a driver fails to stop but is not fleeing, the trooper is supposed to follow safely and request a marked unit rather than escalate; the policy classifies that scenario as a “failure to stop,” not a pursuit.⁸ Whether hard braking in front of a motorcyclist fits anywhere in that framework is likely to be contested at trial.

Is Brake Checking Itself Illegal?

Florida has no statute that names brake checking. The conduct is prosecuted, when it is prosecuted, under the reckless driving statute, Florida Statute § 316.192, which covers operating a vehicle with “willful or wanton disregard for the safety of persons or property.”⁹

On the civil side, a rear-end collision usually carries a presumption that the trailing driver was following too closely. An intentional brake check can flip that presumption, but only if the trailing driver can prove the braking was deliberate rather than a necessary reaction to traffic. That is why helmet-camera and dashcam video so often decides these cases: without it, the lead driver’s version tends to control.

A Comparable Verdict: Wilkens v. Edwards

A 2016 federal case out of Oregon offers a reference point. Motorcyclist Justin Wilkens sued Oregon State Police Captain Rob Edwards after Edwards, driving an unmarked cruiser, struck Wilkens’ bike, threw him from the seat, pointed a gun at his head, and kicked him in the chest. Wilkens suffered broken ribs and a broken clavicle that required surgical repair with plates and screws.¹⁰

After a three-day trial in U.S. District Court in Eugene, a jury awarded Wilkens $180,000 in economic and punitive damages, finding Edwards violated Wilkens’ civil rights during the stop and the physical assault. The jury rejected Edwards’ qualified-immunity defense on the stop and the kick, and found that Wilkens was not harmed by the gun being pointed at him.¹⁰¹¹ The trial judge excluded Wilkens’ prior driving record, including an expired registration, no insurance, and past DUI convictions, which is the same evidentiary fight now playing out in the Whelan motions in limine.

The dollar figures tell their own story. Wilkens’ $180,000 came from a federal jury applying constitutional standards with no state cap in play. Whelan is proceeding under state negligence law, where Florida’s $200,000 per-person cap sits as a ceiling on any recovery short of a legislative claims bill.
