Caution Reversing Vehicles post mount signs are reusable hazard warning signs fitted to posts, fencing and perimeter rails to alert people to reversing traffic ahead. They help staff, visitors and contractors recognise the risk earlier in yards, depots, loading areas and temporary workspaces where vehicle manoeuvres can create sudden danger.

Best Places to Fit Post Mounted Reversing Vehicle Signs

Use this format where a wall is not the right fixing point, such as fence lines, gate approaches, yard perimeters, temporary barriers, depot crossings, loading areas and open vehicle routes. Position it before people step into the manoeuvring area, because the value of a post mounted sign is giving an earlier warning in open spaces where hazards develop fast.

Recommended Viewing Distance for This 400 x 300 mm Sign

For a practical site guide, this size is usually best where the first reading point is about 4 to 7 metres away, or roughly 13 to 23 feet. If people need to read the message from farther back across a wide yard or roadway, you would normally need a larger sign.

What You Improve by Mounting This Sign Properly

When this sign is fixed where people first approach a reversing route, it helps them register the hazard sooner, adjust their movement and avoid drifting into the path of a vehicle that is backing up.

✅ Earlier hazard recognition on open approaches

✅ Clearer warning at fences, gates and yard edges

✅ Better separation between pedestrians and vehicle movement

ⓘ Installation Guidance

How to Use This Post Mounted Vehicle Warning Sign Well

❌ Common siting mistakes

❌ Fixing it inside the hazard area instead of on the approach
❌ Mounting it on cluttered fencing where it blends in
❌ Placing it too low behind parked vehicles or bins

❌ When another option may suit better

❌ Use a wall sign if the risk sits directly beside a building face
❌ Choose a larger format for wide yards with longer read distances

✅ Better installation choices

✅ Fix it to fencing or posts before the crossing point
✅ Keep the face square to the usual line of approach
✅ Use it where flexible, reusable placement is genuinely useful

? Customers Questions

Caution Reversing Vehicles Post Mount Sign Questions Answered

When should you choose a post mount version instead of a wall sign? Choose it when the warning needs to sit on fencing, rails, gates or a freestanding support in an open area where a wall sign would be too far away or less visible.

Is this sign only for temporary use? No. It suits temporary traffic setups very well, but it can also be used for longer-term outdoor warning where you want a reusable sign that can be moved if the route changes.

Why is polypropylene a sensible choice here? It is lightweight, weather-resistant and practical for post or fence fixing, which makes it useful for outdoor vehicle routes and changing site layouts.

Does this sign come with fixings? The sign has pre-drilled holes, but cable ties are available separately, so you can choose the fixing method that suits your post, fence or barrier.

Will this one sign control a reversing hazard on its own? No. It is a clear warning, not a full traffic control system. In higher-risk areas, you may still need barriers, pedestrian segregation, banksman support or additional vehicle safety signs.
