Questions (4)

1. What is the symbol for a marine pollutant?
  1. The image of a bird in a red octagon
  2. The image of a fish in a white triangle with an X through through the fish ✓
  3. A light blue square with a dark blue X through the square

Answer: B. The image of a fish in a white triangle with an X through through the fish

The marine pollutant symbol is a white triangle containing a fish with an X drawn through the fish. The handbook, in its section on the List of Marine Pollutants, describes the Marine Pollutant marking as a white triangle with a fish and an "X" through the fish. It explains that any bulk packages of a marine pollutant must display this marking, and that the same marking must also appear on the outside of the vehicle. So the symbol you are looking for is the fish inside the white triangle crossed out.

3. When should a driver sign a vehicle inspection report?
  1. After every trip
  2. If noted defects are repaired ✓
  3. After each fueling

Answer: B. If noted defects are repaired

A driver should sign the vehicle inspection report if noted defects are repaired or certified as not needing repair. The handbook ties your signature to defect certification, not to completing a trip or stopping for fuel. It says a written inspection report may be required each day, and the motor carrier must fix any safety-related items listed and certify that repairs were done or were not needed. You sign the report only when defects were noted and that certification exists. The passenger-bus section repeats the same idea for reviewing the previous driver's report. That is why the signing point is after noted defects are repaired or cleared.

4. When making a stop to pick up students, a driver should ensure all surrounding traffic has stopped before:
  1. Opening the door and signaling for the students to approach. ✓
  2. Turning on the alternating red lights.
  3. Pulling over to the side of the road.

Answer: A. Opening the door and signaling for the students to approach.

The driver should make sure all surrounding traffic has stopped before opening the door and signaling the students to approach. The handbook tells school bus drivers to make a final check that all traffic has stopped before completely opening the door and signaling students to approach. That places the traffic check right before the door opens and before students are given the signal to come toward the bus. It connects directly to the action of letting students approach, so the driver does not invite them forward until surrounding traffic is stopped.
