It is extremely dangerous to cut off a truck in traffic or on the highway whether you are trying to reach your exit or turn or beat a truck to a single-lane construction zone. Slow down and take your turn, it will only take you a few extra seconds.
Never linger alongside a truck when passing. Always pass a large truck on the left side, and after you have passed, move ahead of it. If you linger beside the truck, you make it difficult, if not impossible, for the trucker to see you and take evasive action without hitting your vehicle, should an obstacle appear in the road ahead.
