This is an important aspect of a truck accident case as the stopping distance is often a question answered through accident reconstruction. To accurately calculate the stopping distance of the vehicle, different factors are taken into consideration.
What factors affect the stopping distance of semi trucks?
When there is rain, snow or ice on the roadway, braking distance is increased significantly. Road conditions can also be an important variable in determining the anticipated stopping distance of a semi truck. Additionally, the tire treads and the manner in which the brakes are applied can affect the stopping distance of semi trucks. Factors that affect the driver’s ability to recognize a danger can also impact the calculation.
What factors are involved in truck accidents?
Another factor that may come into play in a truck accident is the height of the vehicle. Truck drivers may be able to see potential dangers sooner due to their ability to see further distances at their elevated position. When the truck driver perceives the potential danger sooner, he or she can take steps to avoid or minimize the danger. When commercial trucks or passenger vehicles are close to other vehicles because they are traveling too closely, they cannot perceive potential dangers in front of them and will have less time to react.

Stopping Distances for Large Trucks
Large trucks take a significant amount of time and space to stop. When it comes to truck stopping distance vs. car stopping distance, it’s not even close. A car might need a few hundred feet to stop when traveling at highway speeds. But trucks take much longer.
About Truck Braking Systems
Commercial trucks use complex systems known as air brakes. Unlike the hydraulic disc or drum brakes employed on normal passenger cars, these systems use compressed air to bring vehicles to a halt. But while these air brake systems are extremely efficient, they can fail, leading to a loss of control or a failure to stop.
How Long Stopping Distances Contribute to Semi-Truck Accidents
The heavier a truck is and the faster it’s traveling, the longer it needs to stop. That means that a truck driver has to react quicker than a passenger vehicle driver in the same situation. The more room there is for error, the more opportunities there are for something to go wrong. That could mean a more serious accident for you.
