Some vehicles have sight glasses, see-through coolant overflow containers, or coolant recovery containers. These permit you to check the coolant level while the engine is hot. If the container is not part of the pressurized system, the cap can be safely removed, and coolant added even when the engine is at operating temperature.
16 / 50
A. Amount of fuel in the vehicle
B. Cargo securement
C. Whether all vehicle lights are working and clean
During your pre-trip inspection you will need to check cargo securement, and vehicle lights to make sure the vehicle is safe to go on the road. Fuel is a responsibility of the driver to transport the cargo and is not checked on the pre-trip inspection.

B. Constantly blow your horn while passing the vehicle.
C. Assume the other driver does not see you.

A. Downshift while in the curve
B. Downshift as you come out of the curve
C. Downshift at any time, it doesn't make a difference

48 / 50
A. Backing is always dangerous.
B. You should back and turn toward the driver's side whenever possible.
C. Both of the above are true.

49 / 50
A. Apply more pressure to the brake pedal and steer, counter steer
B. Apply more braking pressure to the brake pedal
C. Release brakes and counter steer
Do the following to correct a drive-wheel braking skid: stop braking letting the rear wheels roll again and keep the rear wheels from sliding; counter-steer as a vehicle turns back on course, it tends to keep on turning. Unless you turn the steering wheel quickly the other way, you may find yourself skidding in the opposite direction.
