RA1 Reflective Maximum Height Restriction Signs

Our maximum height restriction signs provide a clear and highly visible way to display vehicle height restrictions at car parks, entrances, loading areas and other restricted-access locations.

Manufactured from 2mm thick aluminium composite and finished with RA1 reflective material, the signs are designed to remain clearly visible in daylight and low-light conditions when illuminated by vehicle headlights.

Signs can display the maximum permitted height in metres and feet, helping drivers identify the height restriction before approaching a barrier or restricted entrance.

Key Features of Height Restriction Signs

  • 2mm aluminium composite construction – lightweight, durable and suitable for outdoor use.
  • RA1 reflective finish – improves visibility in low-light conditions when illuminated by vehicle headlights.
  • Clear maximum height display – available with height restrictions shown in both metres and feet.
  • Multiple sizes available – suitable for different mounting positions and visibility requirements.
  • Custom height options – standard height markings are available, with other restrictions available on request.
  • Suitable for height restriction barriers and entrances – ideal for car parks, commercial premises, loading areas and other vehicle access points.

Please Check Your Height Before Ordering

Height restriction signs are produced to the height marking selected when ordering. Please check that the metric and imperial measurements are correct for your application before placing your order.

Where a sign is produced to a specific or non-standard requirement, it cannot be returned simply because an incorrect height has been selected.

If you're unsure which height marking you require, please contact our team before ordering.

What is the difference between a height restriction sign and a maximum height sign?

There is generally no practical difference between the terms. Both are commonly used to describe signs displaying the maximum vehicle height permitted at an entrance or restricted-access area.

You'll often see these signs used with height restriction barriers and at car parks, loading areas, warehouses and other locations with restricted vehicle clearance.

What Does RA1 Reflective Mean?

RA1 is a retroreflective material designed to reflect light back towards its source. When illuminated by vehicle headlights, the reflective face helps make the height restriction sign more visible in low-light conditions.

This makes RA1 reflective material well suited to height restriction signage positioned at car park entrances, commercial premises and other vehicle access points.

Where Are Height Restriction Signs Used?

Maximum height restriction signs are used wherever drivers need clear warning of restricted vehicle clearance before entering an area.

Common applications include:

  • Car park entrances
  • Height restriction barriers
  • Multi-storey and covered car parks
  • Loading bays and service yards
  • Warehouses and industrial premises
  • Commercial sites
  • Private roads and access points
  • Low-clearance entrances and structures

For the best visibility, the sign should be positioned where approaching drivers have sufficient opportunity to see the displayed height restriction before reaching the restricted area.
