The typical clearance height for a car park height-restriction barrier in the UK is usually between 2.0 metres and 2.2 metres, depending on the site layout and the types of vehicles the car park is intended to accommodate.
Common standards:
- 2.0m – 2.1m
Most common range for public car parks, allowing access for standard cars, SUVs, and small vans while restricting taller vehicles - 2.1m (industry standard)
Widely used as a balanced height — suitable for everyday vehicles but effective at preventing entry of HGVs, large vans, motorhomes, and caravans - 2.2m+
Sometimes used where slightly larger vehicles need access, such as service vehicles or higher-roof vans
When different heights are used:
- Lower heights (under 2.0m) – Rare, typically only used in very restricted or specialist environments
- Higher clearances (2.4m and above) – Used in commercial or mixed-use sites where larger authorised vehicles need regular access
Important considerations:
- The displayed height must match the actual clearance (measured to the underside of the beam)
- Always allow for surface variations, gradients, and vehicle movement
- Clear, reflective signage (e.g. RA1/RA2 height signs) should be installed to warn drivers in advance
