You must not pass another vehicle if you see which conditions?

• A. A solid yellow line in your lane.
• B. A school bus ahead with red flashing lights and an extended stop arm.
• C. An approaching hill or curve with no clear visibility.
• D. Any of these conditions.

Answer: (D)

Passing is allowed only when you have a clear view and it’s legal to do so. In these situations, you must not pass because each one creates a dangerous or illegal condition for passing.

A solid yellow line in your lane signals a no-passing zone. Crossing it to pass would put you into oncoming traffic and reduce your time to react to hazards.

A school bus ahead with red flashing lights and an extended stop arm means all traffic must stop. Passing a stopped school bus is extremely dangerous to children who may be loading or unloading.

An approaching hill or curve with no clear visibility means you can’t see oncoming traffic or obstacles in time to pass safely. You could meet an oncoming vehicle before you can complete the maneuver.

So, any of these conditions require you to refrain from passing.
