When a rear-end collision occurs, the rear driver is generally considered at fault, but this may be overturned if the lead vehicle stops suddenly. If a victim is injured by a tractor-trailer that stops too quickly at highway speeds, cuts into a lane without sufficient space before braking hard, or stops in a prohibited area without proper hazard lights, it may be possible to file a strong liability claim against the truck driver and the trucking company. The Law Offices of Sean M. Cleary provides legal representation to Florida accident victims injured by tractor-trailers and assists them in navigating the complex liability issues that arise when commercial truck drivers create dangerous conditions that lead to serious accidents.
When Sudden Stops Make the Truck Driver Liable
Courts recognize situations in which the lead vehicle's abrupt or improper stop can shift responsibility to the rear driver. It may be considered negligent for a truck driver to brake-check another vehicle or to stop abruptly without a legitimate reason, particularly at highway speeds or in circumstances where such stops are not reasonable. In a similar way, when a tractor-trailer crosses into a lane without allowing sufficient space and then brakes hard, the driver behind it has no time or distance to react safely.
Federal Motor Carrier Safety Administration guidance emphasizes that large trucks must maintain larger following distances because they most often hit the vehicle in front when crashes occur. A fully loaded semi-trailer traveling at 55 mph typically needs around 196 feet to stop under normal conditions, compared with approximately 133 feet for a passenger vehicle at the same speed. The FMCSA recommends at least one second of following distance for every 10 feet of vehicle length, plus another second above 40 mph, which equates to roughly four or more seconds at highway speeds for standard tractor-trailers.
How Florida's Comparative Negligence Rules Affect Compensation Recovery
Florida's 2023 tort reform changed most negligence cases from pure comparative negligence to a modified comparative system under HB 837. Those with more than 50% fault are barred from recovering damages, but those with 50% fault or less are still able to recover damages reduced by their percentage of fault. As long as the plaintiff's share of fault does not exceed 50%, they can still recover damages despite a jury finding the car driver partially responsible for following too closely.
In sudden-stop tractor-trailer cases, the defense will argue that the car driver was following too closely, speeding, or inattentive. The plaintiff must emphasize the truck's unsafe stop, poor hazard use, or dangerous lane change behavior to keep fault allocation at or below the 50% threshold.
Negligence Theories and Available Claims
Violations of FMCSA safety rules on safe following distance, speed management, and braking can support claims that the truck driver failed to act as a reasonably prudent commercial driver. According to the FMCSA's Large Truck Crash Causation Study, brake problems were coded as a contributing vehicle factor for roughly 29% of large trucks involved in serious crashes. In two-vehicle crashes involving a truck and a passenger vehicle, the truck was assigned the critical reason approximately 44% of the time.
Company policies or systemic failures contributing to unsafe stopping practices may make trucking companies directly liable for negligence. Evidence supporting claims that the stop was unreasonable and the crash was predictable includes data from event data recorders showing speed, braking, and throttle position, and dashcam footage showing the truck's brake lights and lane position.
