What does this sign tell you?

Wide yellow rectangle sign with a black border and one large black arrow that points left.
  1. AThe road bends left here; slow down and follow it.

  4. DA detour route to the left begins ahead.
Show the answer and the explanation

Correct answer: A. The road bends left here; slow down and follow it.

Why

This is the One-Direction Large Arrow sign. It stands on the outside of a sharp bend, facing you, and points the way the road goes. Slow down before the bend and steer to follow it. It often adds to a Turn sign placed earlier. Chevron signs do a similar job, but each one is a tall, narrow sign with a V-shaped mark. A black-and-white ONE WAY sign is different: it is a rule for traffic flow, not a curve warning.

Why the other answers are not correct

  • B. One-way streets use a black-and-white ONE WAY sign; this yellow sign warns of a change in road direction.
  • C. A lane that ends has its own Lane Ends sign; this arrow marks a bend in the road.
  • D. Detour arrows are orange; this yellow arrow marks a sharp bend in the road.
