Following too closely behind a large vehicle is not a good idea because:
You will have to keep braking and your brakes will overheat
You will get pulled along in its slipstream
Your visibility will be impeded
Explanation: Give a truck extra space and keep ample distance when driving in front of or behind a large truck, and choose another lane if a semi truck is driving too closely behind you. Tractor-trailers need substantially more space than a car does to come to a complete stop in an emergency.
