3. Where a cross-buck has no painted stop line, how far from the nearest rail must a vehicle required to stop actually stop?

4. What is the manual's overall advice about backing a large vehicle?
Correct answer: Avoid backing whenever you can
Because you cannot see everything behind you, backing is always risky; avoid it when possible and park so you can pull forward to leave.

5. What gear and speed are recommended when backing?
Correct answer: The lowest reverse gear, as slowly as possible
Back as slowly as you can in the lowest reverse gear; the slow pace lets you correct steering errors and stop quickly if needed.

6. On a one-way or divided highway, where do you place the three warning devices?
Correct answer: 10, 100, and 200 feet toward approaching traffic

7. What should you never do while your vehicle is crossing railroad tracks?
Correct answer: Shift gears
Do not change gears while on the tracks; you might stall or lose momentum, so be sure you can clear the crossing completely before you start across.

8. On a two-lane road carrying traffic both ways, how are the warning devices placed?
Correct answer: Within 10 feet of the vehicle, plus 100 feet ahead and 100 feet behind
On an undivided two-way road, mark the vehicle within 10 feet at a corner and place devices about 100 feet to the front and 100 feet to the rear.

9. If a hill or curve blocks the view of your stopped vehicle, what should you do with a warning device?
Correct answer: Move the rear-most triangle farther back so drivers get warning within 500 feet
When a hill or curve hides the vehicle, back the farthest triangle down the road so approaching drivers still get a warning within 500 feet of the obstruction.

10. What should you always do with the parking brake when you leave the vehicle?
Correct answer: Apply it
Set the parking brake every time you step away from the vehicle so it cannot roll, and fasten your safety belt whenever you are driving.

11. After stopping on the road or shoulder, within how long must you put out your emergency warning devices?
Correct answer: Within 10 minutes
Emergency warning devices must be placed within ten minutes of stopping on a road or shoulder, and this matters most at night.

12. On a manual-transmission vehicle, how do you keep from rolling backward when starting on an upgrade?
Correct answer: Partly engage the clutch before releasing the brake, using the parking brake as needed
Partly engage the clutch before your foot leaves the brake and use the parking brake if necessary, releasing it only once you have enough power to hold position.
