The time and distance tractor-trailers and other commercial trucks need to come to a complete stop is much greater than that of smaller passenger vehicles, such as cars or pickups.
The stopping distance of semi-trucks vs. cars is calculated as follows:
A normal passenger vehicle driving at 65 miles per hour will need about 300 feet to stop.
A fully loaded commercial truck driving at 65 miles per hour will need about 600 feet to stop.
For a more visual comparison, a car takes about the length of a football field to stop, while a semi-truck needs the distance of approximately two football fields to stop.
Additionally, stopping distance can vary significantly based on road conditions and other factors.
