Do Not Obstruct Post Mount Signs help you keep gates, entrances and restricted outdoor access points clear. The red prohibition symbol and direct wording support drivers, visitors and staff where blocked routes could delay movement or create avoidable risk.

Where Do Not Obstruct Post Mount Signs Should Be Installed

Install these signs on posts, mesh fencing or temporary barriers beside gates, access roads, loading entrances and service routes. Position them before drivers stop, not after they have already blocked the route, so the instruction is visible while decisions are being made.

Viewing Distance Guidance For Outdoor Access Control

For a 400 x 300 mm sign, place it where drivers can read the message before stopping or turning. Around 5–10 metres is suitable for slower yards and entrances, while longer approaches may need repeated signs rather than relying on one distant display.

H 400 x W 300 mm	Approx. 5–10 metres in slow-moving outdoor areas	Gates, fence lines, yards and service entrances
