- A no-passing zone on a hill
- A school zone or school crossing

Show the answer
C. A school zone or school crossing

A yellow pennant-shaped sign (a sideways triangle) posted on the left side of a two-lane road marks what?
- The start of a no-passing zone

- A lane that is ending ahead
- A sharp left-hand curve just ahead
Show the answer
A. The start of a no-passing zone
The pennant is used only for the no-passing zone sign and is placed on the left side of the road where a driver thinking about passing will see it. A lane ending or a curve is shown on a diamond-shaped warning sign.
