Beneath a warning triangle, a plate shows '400 yds' with an arrow pointing left. What information is the plate adding?
The current road bends left continuously for 400 yards.
A mandatory left turn begins at the sign itself.
The warned hazard lies 400 yards along the road to the left.✓Correct answer
The hazard extends 400 yards on both sides of the junction.
Explanation
The distance and arrow locate the hazard along the road to the left, rather than directly ahead on the current route. Reading the arrow as a mandatory turn would confuse a supplementary locator with a blue circular instruction.
