1 . The Individual Vehicle Distance Record (IVDR) does not need to include which of the following?

An Individual Vehicle Distance Record (IVDR) must include information about the distance traveled by a vehicle and the amount of fuel purchased. The required distance information includes the origin and destination points of the trip and the Vehicle Identification Number.

2 . During a basic vehicle control skills test, a look is when:

A driver uses a look when they open their door, leave their seated position, and walk to the back of the vehicle to check its position. During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.

3 . What kind of force do emergency brakes use?

Air brakes are really three different braking systems: the service brake, the parking brake, and the emergency brake. Emergency and parking brakes are applied with mechanical force.

4 . On flat surfaces, wheel chocks:

In situations where a driver cannot use a parking brake, wheel chocks can be used to hold a parked vehicle in place on a level surface.

5 . On a slippery road, a driver should:

Under slippery conditions, you should drive slowly and smoothly. Make turns as gently as possible and do not pass other vehicles unless you have to.

6 . Looking far ahead of your vehicle while driving is:

Good drivers look down the road at least 12 to 15 seconds ahead of their vehicles. This makes it possible to identify hazards early, when drivers are more likely to have time to respond appropriately.

7 . If you must leave the roadway and drive on the shoulder in an emergency situation, you should:

If you must drive onto the shoulder to avoid a hazard, stay on it until you come to a stop; then signal, check your mirrors, and merge back into traffic. Avoid braking on the shoulder at speeds higher than about 20 mph. To help maintain control, always keep one set of wheels on the pavement, if possible.
