2. Why are slow-moving trucks at risk of being hit from behind, according to the manual?
Correct answer: Drivers often don't realize how fast they are closing on a slow vehicle until they are right behind it

3. On a multilane road, what is the manual's first suggestion for avoiding the dangers of traveling next to other vehicles?
Correct answer: Look for a clear stretch of road away from other vehicles

4. A car ahead brakes hard near an exit — a hazard. It then cuts directly in front of your truck. What does the manual now call the situation?
Correct answer: An emergency
A hazard is a possible danger. Once the car actually cuts in front of you, the manual says it has stopped being just a hazard and has become an emergency.
