- As soon as the truck begins to swing wide

When you meet a truck coming from the opposite direction, where should you keep your vehicle?
- Close to the center line of the roadway
- On the shoulder with your wheels off the pavement
- As far as possible to the right side of the roadway
- In the middle of your lane, away from both edges
Show answer
Correct answer: As far as possible to the right side of the roadway
Keeping as far right as possible avoids a side-swept crash and reduces the wind turbulence between the two vehicles, which pushes them apart.

Why do stop lines at intersections matter when large vehicles are nearby?
- They set you farther back so larger vehicles have more turning space
- They show large vehicles where they must wait for you
- They mark the lane that only large vehicles may use
- They keep large vehicles out of the crosswalk while turning
Show answer
Correct answer: They set you farther back so larger vehicles have more turning space
Stop lines help to set you farther back at an intersection to give larger vehicles more turning space, so you should always stop behind them.

-
Which of these should you NOT do around large vehicles?
- Stop behind the stop line at an intersection with a large vehicle
- Give a turning truck or bus plenty of room to maneuver
- Keep as far right as possible when meeting a truck
- Cut off a truck to beat it into a single-lane construction zone
Show answer
Correct answer: Cut off a truck to beat it into a single-lane construction zone
You should not cut off a large vehicle in traffic or on the highway; the few seconds that might be saved are not worth a life.

- Slow-moving trucks will be trying to reenter faster-moving traffic
Show answer
