A farm vehicle has this sign on its back. What does it warn you about?
The rule
The slow-moving vehicle sign on the back of a farm vehicle, horse-drawn vehicle or bicycle warns that it goes 25 mph or less.
Some slow vehicles, like farm vehicles, carry this sign to warn you they are going 25 mph or less.
From the Maryland Driver's Manual, Section 5, page 32. This question is our own wording of that rule. The handbook and the MVA have the final word.
