What does the yellow bump warning sign mean?

Yellow diamond warning sign with the word BUMP in black letters.
Correct answer

A bump or uneven pavement is ahead. Slow down and keep control

This sign warns of a bump or uneven pavement on the road ahead. Slow down and keep firm control of your vehicle.

Why the other answers are wrong

  • A speed bump may be removed ahead

    Warning signs tell you what the road does ahead, not what crews plan to change. Treat the word BUMP as a signal to slow down now.

  • A loading dock is ahead

    Nothing on this sign mentions loading. Loading and unloading rules appear on regulatory parking signs at the curb, never on a yellow diamond about the road surface.

  • The road ahead is freshly paved and smooth

    This is the opposite. A yellow diamond only appears where there is something to watch out for, so BUMP means uneven pavement, not fresh smooth asphalt.

Quick way to remember

Read the word: it describes the road surface ahead.

Based on the official Ontario MTO Driver's Handbook.
