Bump
warning sign · diamond · yellow
A raised spot in the pavement ahead — slow down or risk bottoming out, losing grip, or jolting the cargo and passengers.
- Visual breakdown
- Yellow diamond with the word BUMP.
- Shape recognition
- Word-message diamond: when the hazard has no easy pictograph, MUTCD just says it.
- Color recognition
- Yellow pavement-condition warning, sibling of DIP and PAVEMENT ENDS.
- Memory trick
- BUMP lifts the car — and lifted tires don't steer or brake. Speed decides whether it's a nudge or a launch.
- Real-world example
- A frost heave taken at 55 unloads the suspension right where the road curves — the classic single-car run-off.
- Common mistakes
- Braking hard on the bump itself; brake before, roll over it with steady speed.
- Quick recall method
- BUMP = up. Slow before, steady over.
