1. A vehicle stopped at a green light may indicate that the driver:
- Is impaired. ✓
- Is colorblind.
- Does not know the rules of the road.
- Is very patient.
Answer: A. Is impaired.
A vehicle stopped at a green light may indicate that the driver is impaired. The handbook lists stopping at a green light, along with waiting too long at a stop, as stopping at the wrong time. It places that behavior with weaving, drifting, and leaving the road, actions that show a driver is not responding normally to the traffic situation. Among the choices, impairment fits a driver who fails to go on a green signal; the passage does not tie the stop to colorblindness, rule ignorance, or patience.
2. What is the symbol for a marine pollutant?
- The image of a waves in a yellow triangle with an X through through the waves
- The image of a fish in a white triangle with an X through through the fish ✓
- A light blue square with a dark blue X through the square
- The image of a bird in a red octagon
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 says any bulk package of a marine pollutant must show the Marine Pollutant marking: a white triangle with a fish and an X through the fish. It also says this is a marking, not a placard, and that it must appear on the outside of the vehicle as well as on the package. So the symbol to look for is the fish inside the white triangle with the X crossing the fish.
