Do not pass:

  1. On a hill or curve.
  2. When school bus lights are flashing.
  3. When approaching an intersection.
  4. All of the above. ✓

Answer: D. All of the above.

Do not pass in any of these situations: on a hill or curve, when a school bus is flashing its lights, or when you are approaching an intersection.

Why this is the answer

The handbook lists places where you must stay off the left side of the road for passing. That list includes hills, curves, and other spots where you cannot see far ahead, and it also covers being within 100 feet of or crossing an intersection. Separately, when a school bus is showing alternately flashing red lights, you must stop and not pass until the bus moves, the driver signals you, or the lights stop. Since each situation in the choices is a place where passing is barred, they all apply.

Why the other answers are wrong

Remember it

Think of the three things that hide danger from you or hide you from others: a blind hill or curve, a stopped school bus, and an intersection ahead. Any one of them means stay in your lane.
