Ouch! While you were on a roll there for a few questions, you didn’t pass this time. But I know this test, and I think you’ll pass next time. Really.

1. An item that is 40 feet long placed on a flatbed trailer should be secured by at least ____ tie-down(s).

2. When in heavy traffic, the safest driving speed is:
Slower than the speed being driven by surrounding traffic.
The same speed being driven by surrounding traffic.
Faster than the speed being driven by surrounding traffic.

In heavy traffic, it is safest to travel at the same speed as other vehicles. If two vehicles continue to drive in the same direction at the same speed, they cannot hit each other.

If approaching a railroad crossing while driving a transit bus, school bus, or placarded vehicle, special procedures apply. Before crossing, stop your vehicle within 50 feet of, but not less than 15 feet from, the nearest rail. Activate your four-way flashers while crossing. Do not stop, change gears, or change lanes while any part of your vehicle is proceeding across the tracks.

5. When transporting cargo, drivers must check the securement of the cargo every:
10 miles.
150 miles.
500 miles.

Mono air brake systems.
Dual air brake systems.

7. A cargo van carrying a light load is usually:
The same height as when carrying a heavy load.
Taller than when carrying a heavy load.
Shorter than when carrying a heavy load.
Less stable than when carrying a heavier load.

The added weight of a heavy load will make a vehicle sit lower than usual. A vehicle will often be taller when carrying a light load than when carrying a heavy load. If your vehicle fits under an overpass while carrying a full load, it is not guaranteed that it will fit under the same overpass if it is empty.

8. When cargo is being loaded, weight should be placed:
