low clearance
Watch your head
Low clearance describes a space with limited vertical room—typically a warning that tall vehicles may not fit.
Signs reading low clearance appear at bridges, tunnels, and parking garages, often with a height measurement.
The phrase can describe any overhead obstruction: Watch your head—low clearance through here.
