Who is at Fault When a Semi Truck Tire Hits Your Car?
Driving down the interstate, you suddenly see a massive, heavy chunk of black rubber violently flying toward your windshield. Commercial truck tire tread separations—commonly known as "road gators"—are incredibly dangerous. Because a single truck tire can weigh over 100 pounds, an impact at highway speeds can obliterate a passenger vehicle, shatter glass, and cause fatal rollovers.
Trucking companies often claim these events are "acts of God" or unavoidable road hazards to escape liability. If you suffered property damage or severe injuries, it is critical to understand exactly who is at fault when a semi truck tire hits your car.
Under Federal Motor Carrier Safety Administration (FMCSA) regulations, trucking companies have a non-delegable duty to inspect and maintain their equipment. Tire blowouts and tread separations are almost never "accidents"; they are the direct result of poor maintenance practices designed to save the company money.
Proving the Trucking Company is Liable
To hold the motor carrier financially responsible for the damage, your legal team will investigate the specific cause of the tire failure:
- Defective Retreads: Many fleets use cheap "retread" tires on their trailers (gluing new tread onto old tire casings). If the retread process was faulty, or the tire casing was too old, the tread will peel off entirely at high speeds. The trucking company and the tire manufacturer can both be held liable.
- Underinflation and Heat Buildup: Driving on an underinflated tire creates immense internal friction and heat. Eventually, this thermal stress causes the rubber to violently explode. Drivers are required to check tire pressure during their daily Pre-Trip Inspections. Failing to do so is negligence.
- Ignoring Bald Tires: FMCSA rules require specific tread depths (4/32 inch for steer tires, 2/32 inch for others). If maintenance logs show the company ignored warnings from mechanics and dispatched a truck with bald, rotting tires, they are strictly liable for the ensuing crash.
Securing Compensation
If the truck driver kept driving after the blowout, try to get their DOT number, license plate, or company name from the trailer. A skilled personal injury lawyer will subpoena the company's maintenance records, driver inspection logs, and dashcam footage to prove they knowingly put a dangerous vehicle on the highway.
