1. What gear should you be in as you take a curve?
Correct answer: One that lets you accelerate slightly through the curve
Slow to a safe speed before the curve and be in a gear that allows slight acceleration through it. That helps keep control.

2. On packed snow, how much should you cut your speed?
Correct answer: By half or more
Slow by about a third on wet roads, by half or more on packed snow, and to a crawl on ice.

3. You are hauling a partial load of livestock. What does the manual suggest?
Correct answer: Use false bulkheads to keep the animals bunched together
Livestock moving around makes handling unsafe. With less than a full load, false bulkheads keep them grouped, though they can still lean on curves and raise rollover risk.

4. What can happen if you force a downshift in an automatic transmission at high speed?
Correct answer: The transmission can be damaged and all engine braking can be lost
Forcing a downshift at high speed in an automatic can damage the transmission and cost you the engine braking you need.

5. Which sign tells you ice has formed on the road?
Correct answer: Vehicles ahead are no longer throwing up spray
A lack of spray from other vehicles means ice has formed. Ice on your mirrors or wiper blades also suggests the road is icy.

6. In a work zone, when should you slow down even below the posted limit?
Correct answer: When a worker is near the road, or weather and road conditions are poor
Keep to the posted work zone limits, slow down for adverse conditions, and slow further when a worker is near the road.

7. What problem can drainage channels across a road cause for some vehicles?
Correct answer: The ends of the vehicle can drag
A heavily loaded vehicle may have little clearance underneath. Cross drainage channels and other dips carefully, since the ends of some vehicles may drag.

8. What makes hanging meat in a refrigerated trailer a difficult load?
Correct answer: It can be very unstable with a high center of gravity, especially on sharp curves like ramps
Suspended beef, pork or lamb sits high and can be unstable, so take sharp curves such as on and off ramps slowly.

9. How does vehicle weight affect the work your brakes do?
Correct answer: A heavier vehicle makes the brakes work harder and absorb more heat
Extra weight means the brakes have to do more work to stop the vehicle, and they absorb more heat doing it.

10. Why do dry bulk tanks require extra care on curves and sharp turns?
Correct answer: They ride with a high center of gravity, and their load can move
Dry bulk tanks sit high and their load can move, so go slowly and carefully through curves and sharp turns.
