Which sign meaning is ‘Road weight limit’?

• A. Stop ahead
• B. Curve warning
• C. Bridge clearance sign
• D. Road weight limit

Answer: (D)

Weight limit signs tell you the maximum weight that a road or bridge can safely carry. They’re there to protect the infrastructure from damage that can happen if a vehicle is too heavy, so you need to know your vehicle’s load and only proceed if it’s at or below the posted limit. The sign typically shows the limit in tons, so you’ll see something like a number with a unit indicating the maximum allowable weight.

Other signs have different meanings: a sign that says stop ahead warns you that a stop sign is coming; a curve warning sign alerts you to an upcoming bend in the road; and a bridge clearance sign shows the vertical height you must be under, which is a height restriction, not weight.
