To Pass

29 . If you are being tailgated, you should:

Allow the vehicle to pass. If you are being tailgated, it is best to allow more room to open up in front of your vehicle. This will help you avoid the need for sudden stops, which could result in the tailgater rear-ending you, and will make it easier for the tailgater to pass. Speeding up may only make things more dangerous by prompting the other driver to continue tailgating you at a higher speed.

30 . If you’re feeling tired before a drive, you should:

Drive as fast as possible so you get to the destination quickly. Stimulant drugs, including caffeine, are not helpful as a way of avoiding fatigue. They may help keep you awake, but will not make you any more alert. Feeling tired is a sign that your body needs sleep, and the only way to properly address it is to stop driving and get some sleep.

31 . In hot weather, spots on the pavement where tar is bleeding:

Tar in road pavement often rises to the surface of the road, or "bleeds," in very hot weather. Watch for such areas because they can be very slippery.

32 . A low air pressure warning signal should activate:

When tank pressure falls below 5 psi. In an air brake system, a low air pressure warning signal must come on if air pressure in the tanks falls below 60 psi. This warning signal may come in the form of a light, a buzzer, or a wig wag.

33 . When checking power steering hoses during a pre-trip inspection, you should look for:

When doing a pre-trip inspection on a vehicle with power steering, be sure to check the hoses, pumps, and fluid level. In particular, you should check the hoses for leaks.

34 . When coming to a stop, you should apply the brake pedal by:

When stopping, you should push the brake pedal down gradually. Braking gradually will help you to maintain proper control of your vehicle.

35 . Which of the following is not a reason to cover cargo?

You should cover your cargo to protect people from the cargo if it spills, as well as to protect the cargo from the weather.
