Unroadworthy Vehicles: The Dangers and Who Is Liable

A car is only as safe as its worst-maintained part. Bald tires, failing brakes, burned-out lights, and defective components cause preventable crashes every year. When an unroadworthy vehicle leads to a collision, the question becomes who is responsible, and the answer is not always the driver alone.

The short answer

Drivers have a duty to keep their vehicles reasonably safe. When neglected maintenance, or a defective part, causes a crash, liability can fall on the driver, a repair shop, or a manufacturer, depending on what went wrong. Preserving the vehicle and its records is key to proving the cause.

Common unroadworthy hazards

  • Worn or bald tires that lose grip or blow out.
  • Failing brakes or worn pads that increase stopping distance.
  • Broken lights and signals that make a vehicle hard to see or predict.
  • Defective parts, from steering and suspension to airbags and accelerators.
  • Neglected recalls that leave a known danger unaddressed.

Who can be held responsible

Fault depends on the source of the problem:

  • The driver or owner, for ignoring obvious maintenance needs.
  • A repair shop, for faulty or incomplete work that caused the failure.
  • A manufacturer, for a defective part or a design flaw, which can lead to a product liability claim.

Proving the cause

Vehicle-condition cases turn on evidence. Preserving the car, having it inspected by a qualified expert, and gathering maintenance records, recall history, and crash data can reveal whether a failure was due to neglect or a defect, and who should answer for it.

Do not let the vehicle disappear. Once a car is repaired, scrapped, or released, key evidence can be lost. If you suspect a mechanical failure or defect caused your crash, acting quickly to preserve the vehicle can make or break the case.
