According to FMCSA, trucks are often 20 to 30 times heavier than passenger vehicles.
The Stopping Time Of A Semi Truck
When the truck travels faster than 18 mph, it can brake in time. The stopping time is about three times the normal stopping distance. So at 55 mph, it will take about 165 feet (50 meters) to stop from that speed using a dead-stop.
Longer Stopping Distance Equals Greater Risk
The greater stopping distance of a semi-truck is due to the sheer size and weight of these vehicles, making it harder for them to stop in time. If the brake system fails or there is a problem with the brakes, the truck’s stopping distance is even greater.
Conclusion
The longer stopping distance of a semi-truck is something that every driver has to account for in their driving. You don’t want to get into an accident situation because you wouldn’t be able to avoid it if the truck doesn’t have enough braking power or time to come to a complete stop.
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.

How far does it take for a truck to stop?
A normal passenger vehicle such as a car or small pickup truck will normally take approximately 316 feet to come to a complete stop after recognizing the need to stop. In comparison, a semi truck takes about 525 feet before it comes to a complete stop after recognizing the need to stop. 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 come into play in a truck accident?
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.
