Low Clearance
warning sign · diamond · yellow
The overpass ahead is lower than standard. Vehicles taller than the posted height cannot pass.
- Visual breakdown
- Yellow diamond with a height figure (feet and inches) between arrows pointing up and down.
- Shape recognition
- Diamond with a measurement — the number is the entire message.
- Color recognition
- Yellow physical-hazard warning: the bridge will not move for you.
- Memory trick
- The bridge always wins. Know your height (especially in a truck or with a roof box) before the number matters.
- Real-world example
- A rental box truck is about 12 feet tall; a 12'6" bridge leaves inches — take the posted truck route instead.
- Common mistakes
- Drivers of rentals and RVs not knowing their vehicle height at all.
- Quick recall method
- Posted height < your height = detour, no exceptions.
