1. Why should you never let traffic conditions trap you into stopping on railroad tracks?
Correct answer: A train could strike you before you can clear the tracks

2. After you pull onto the shoulder and come to a stop, what should you always switch on?
Correct answer: The four-way emergency flashers
Turn on the four-way emergency flashers whenever you stop at the side of the road; taillights alone have led following drivers to crash into parked vehicles they thought were moving.

5. Why should you avoid backing a commercial vehicle whenever you can?

Correct answer: Within 10 feet of the vehicle and about 100 feet ahead and behind it

9. When you must stop at a railroad crossing, what is a safe way to warn drivers behind you?

10. If a hill or curve keeps drivers from seeing your stopped vehicle within 500 feet, what should you do with the rear triangle?
Correct answer: Move it farther back beyond the hill or curve
Move the rearmost triangle farther back down the road, beyond the hill or curve, so that approaching drivers get warning before they reach the obstruction.

11. When you park a commercial vehicle, how should you try to position it?
Correct answer: So that you can drive straight out when you leave
Because backing is always dangerous, park so that you can pull forward when you leave rather than having to back out into traffic.
