low bridge
Truckers beware here
Low bridge is a warning cry, originally shouted to passengers on canal boats approaching a bridge with little clearance overhead—duck or get knocked off.
The phrase survives in the folk song "Low Bridge, Everybody Down" about the Erie Canal.
More broadly, it warns of any low overhead obstacle: Low bridge—watch your head in the basement.
