A yellow diamond sign. Two arrows point up and down between two horizontal lines. The words 3.75 m are on the sign.

What does the number on this sign tell you?

  1. The speed limit in the underpass
  2. The weight limit of the road
  3. The length of the underpass
  4. The height of the overhead clearance
Show answer

Correct answer: The height of the overhead clearance

A low clearance sign warns of an underpass with limited height. Do not go in if your vehicle is taller than the number.
