Where you see itBefore underpasses and parking structures

What it means

The bridge or structure ahead is lower than standard. The posted measurement is the maximum height that fits.

What you should do

Know your vehicle’s height, especially with a truck, RV, or roof load. If your height is at or above the number, take the marked detour; there is no squeezing through.

Memory trick

The number is a doorframe for your vehicle. Taller than the door means the door wins.

The mistake drivers make

Rental-truck drivers trusting car habits. The classic crash under every low bridge is a moving truck whose driver never thought about height before that day.
