Explanation
When transporting cargo on a flatbed trailer, you should use at least one tie-down for every 10 feet of cargo. Any cargo, no matter how small, should be restrained by a minimum of two tie-downs.

37. If turning to avoid a hazard:

Explanation
If you are turning to avoid a hazard, do not apply the brakes while you are turning. This could easily lock the wheels and create a skid.

38. When a vehicle is started, warning lights and buzzers:

Explanation
After an engine is started, the warning lights and buzzers for oil, coolant, charging circuits, and the Anti-Lock Braking System (ABS) should go out right away.

39. Headlights:

Explanation
To improve visibility, you should use high beam headlights at night where it is safe and legal to do so. However, the glare from high beam lights can blind other drivers. You should dim your lights to their low beam setting when driving within 500 feet of an approaching vehicle.

40. How much water must be present for a vehicle to hydroplane?

Explanation
Hydroplaning is a phenomenon during which a vehicle's tires lose traction with the road surface and begin to glide along on water on the road. There does not have to be a large amount of water on the road for this to occur.

41. What is brake lag?

Explanation
Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work. On vehicles with hydraulic brakes, the brakes work instantly when the pedal is pressed.

42. During exercises that are not the straight line backing exercise, you may exit your vehicle to check its position no more than:

Explanation
A driver is allowed to exit their vehicle to check its position during any basic control skills test exercise. This action is called a "look." During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.
