Runaway truck incidents are among the most dangerous events that can happen on highways. When a large truck loses its ability to stop, the outcome can be catastrophic. These incidents often happen on steep grades or long downhill stretches and can lead to serious collisions with other vehicles.
A runaway truck does not always indicate driver negligence. Often, these incidents result from mechanical failure, poor maintenance or other preventable factors. Understanding the common causes can help identify liability in a truck accident and improve overall road safety.
1. Brake fade from overheating
Brake fade occurs when a truck’s braking system overheats due to prolonged or excessive use. This is especially common during long downhill drives. As the brakes get hotter, they become less effective at slowing the vehicle. Once brake fade sets in, the driver may have little control over the speed of the truck.
2. Mechanical brake failure
In some cases, the braking system fails entirely. This can happen due to worn brake pads, fluid leaks or broken components. If the primary and backup braking systems fail together, the truck can become a runaway vehicle within seconds. Brake failure is often linked to poor maintenance practices.
3. Overloaded or improperly balanced cargo
Trucks must follow strict weight and load balance regulations. If the cargo is too heavy or unevenly distributed, it can increase the strain on the brakes and reduce the driver’s ability to maintain control. An overloaded truck gains speed more quickly downhill, making braking even more difficult.
4. Lack of maintenance or inspections
Routine inspections and servicing are critical to keeping trucks safe. When carriers skip scheduled maintenance or overlook warning signs, they increase the risk of component failures. Brakes, tires and engine systems must be checked regularly to prevent sudden mechanical breakdowns during operation.
Runaway truck incidents can have lasting consequences for everyone involved. If you or a loved one has been harmed in a truck accident involving brake failure or equipment malfunction, seeking legal guidance may be helpful in understanding your rights and options.
