Traffic sign for road use

The Lyle R4-1-18HA is a regulatory Do Not Pass sign made from aluminium. It measures 24 inches high by 18 inches wide and uses a vertical rectangle layout. The face is printed in black and white with English text. Mounting holes allow fixed installation on posts or walls.

Limits of a static aluminium sign

This sign conveys a single fixed message and cannot be changed electronically. It relies on external light sources or vehicle headlights for night visibility. The aluminium construction resists corrosion but offers no illumination of its own. It is restricted to the specific R4-1 legend shown.

Aluminium build with mounting holes

The sheet aluminium body withstands outdoor exposure without rusting. Pre-drilled mounting holes accept standard bolts or screws for permanent attachment. The rigid panel keeps its shape in wind and handles typical roadside vibration. No wiring or power supply is required for operation.
