Sharing the RoadStandalone practice
You follow a tractor-trailer by about 100 feet on a highway. You cannot see either of its side mirrors. What is the best conclusion?
Correct answer: The driver probably cannot see you, because a truck's rear blind area can reach about 200 feet
Why
Large trucks and buses have blind areas, called no zones, in front of the cab, along both sides of the trailer and far behind it. Put your car where you can see the driver's side mirrors, and do not stay beside a truck longer than you must. When you follow farther back, you can also see more of the road ahead.
