Question

a red and white triangular sign at an intersection means:
a. slow down if an emergency vehicle is approaching
b. look both ways as you cross the intersection
c. always come to a full stop at the intersection
d. slow down and be prepared to stop if necessary

Explanation:

A red and white triangular sign at an intersection is a yield sign. A yield sign means drivers should slow down and be prepared to stop if necessary to let other traffic or pedestrians pass. Option A is incorrect as it relates to emergency vehicle procedures (usually for other signs or situations). Option B is incorrect as looking both ways is a general safety practice but not the meaning of the yield sign. Option C is incorrect as a full stop is required for a stop sign, not a yield sign. Option D matches the meaning of a yield sign.

Answer:

D. Slow down and be prepared to stop if necessary
