1. Which of the following is not an indicator of when to change gears?

There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.

2. If a gate controlling a railroad crossing does not go back up after a train passes, you should:

If you are stopped at a railroad crossing and a gate fails to return to its open position after a train passes, call your dispatcher. Do not attempt to drive around the lowered gate.

3. If a driver needs to exit a school bus to ensure all waiting students have boarded, the driver should:

While students are boarding a school bus, if the driver cannot account for a student outside, they should secure the bus, take the key with them, and check around and underneath the bus for the missing student.

5. In very hot weather, the air pressure in tires may increase.

Air expands as its temperature increases, so air pressure in your tires is likely to increase when you are driving in very hot weather. Under such conditions, stop periodically to ensure that your tires are not at risk of blowing out or catching fire.

6. If federal inspectors judge your vehicle to be unsafe, they can:

If a federal or state inspector judges a CMV to be unsafe, they may put it out-of-service until it is fixed.

7. If a load is 10 feet long, it must be secured by a minimum of ____ tie-downs.

On flatbed trailers and trailers without sides, cargo must be tied down. There should be at least one tie-down for every 10 feet of cargo. Regardless of the size of the cargo, at least two tie-downs must be used.
