5mph Speed Roundel

Clear 5mph Speed Limit Control for Your Car Park in One Durable Marking

A 5mph Speed Roundel gives drivers an immediate, highly visible reminder of the 5mph speed limit in car parks, private roads, warehouses and other off-highway areas where vehicles and pedestrians share the same space.

key features: Designed as a durable thermoplastic road marking, this tri-colour speed roundel helps improve site safety, support smoother traffic flow and reduce confusion around speed limits without relying on upright signage alone. It is especially effective when used with car park directional arrows to create a clear, easy-to-follow traffic management layout.

In the UK, 5mph speed roundels are exclusively used on private property and off-highway areas. They are advisory rather than enforceable under public traffic laws, but they are valuable for landowners and facility managers who have a duty of care to manage workplace traffic safely under the Health and Safety at Work etc. Act 1974.

Why You’ll Love It

• Enhanced Safety – Clear 5mph speed communication helps reduce accident risk in high-risk zones where pedestrians, cars, delivery vehicles and workplace traffic operate close together.

• Time-Saving Installation – The pre-cut thermoplastic design supports easy application and can be applied quickly using a gas torch, helping installation teams cover large areas efficiently.

• Long-Lasting Durability – Thermoplastic markings are known for durability and longevity, making them suitable for car parks, parking bays, road line markings and private access routes.

• Professional Appearance – The consistent tri-colour design in red, white and black mirrors familiar road marking layouts, giving your site a neat, credible and easily recognisable finish.

• Versatile Size Options – Available from 600mm x 600mm up to 7600mm x 1500mm, including elongated formats that improve legibility for approaching drivers.

• Speed Variations - This speed roundel comes in various different speed limits including 5mph, 10mph ,20mph, 30mph,40mph, 50mph and 60mph 

Physical calming methods, such as speed bumps, are commonly installed alongside 5mph roundels because drivers tend to naturally accelerate due to the low speed limit. Traffic engineering guidelines recommend installing heavy-duty speed bumps spaced tightly between 20 and 150 meters apart to control 5mph speeds on private roads.

What Makes It Different

Most speed markings are hand-painted, stencil-based or basic white markings that can fade quickly and lack impact. This 5mph Speed Roundel is built for stronger visibility, cleaner installation and longer service life.

• Pre-Cut Precision – Factory-cut roundels help ensure the correct size and shape, supporting consistency and compliance with road safety standards for private sites.

• Tri-Colour Design – The red, white and black combination provides strong contrast, helping motorists recognise the 5mph speed limit quickly in car parks and other shared traffic areas.

• Thermoplastic Material – Thermoplastic road markings last longer than paint-based alternatives and often include reflective components to enhance visibility and safety in all weather conditions.

• Perfect Integration – The 5mph option works perfectly with car park directional arrows, pedestrian crossings, parking bay markings and other traffic control features.

For credibility, 5mph signs and ground roundels in parking lots should mirror standard road designs. If implementing 5mph signage, it should conform to Diagram 670 standards with a circular design featuring a red border, white background and black numbers. For nighttime visibility, physical signs or ground roundels should also feature ISO 7010 compliance or BS EN 12899-1 reflective laminates where appropriate.

How It Works

1. Step 1 – Surface Preparation
   Clean and prepare the target installation area by removing loose debris, dirt, oil and surface contamination. The 5mph speed roundel is suitable for asphalt and concrete car park surfaces, with correct preparation helping the thermoplastic material bond properly.

2. Step 2 – Heat Application
   Position the pre-formed marking, then apply heat with a gas torch to activate the thermoplastic adhesive properties. These markings can be applied quickly using a gas torch, allowing efficient installation across car parks, warehouses and industrial estates.

3. Step 3 – Instant Results
   Once bonded, the site has a permanent 5mph speed marking ready for traffic use. The tri-colour design gives drivers a clear visual cue, while reflective materials can improve visibility in rain, sun and varied lighting conditions.

5mph roundels marked on the road surface should be elongated vertically to ensure they are legible to approaching drivers. Larger sizes, including formats up to 7600mm x 1500mm, are useful where drivers need more time to identify the speed roundel from a distance.

Important legal note: the lowest enforceable national speed limit on public roads in the UK is 20mph, making a 5mph limit unenforceable on public highways. The Traffic Signs Regulations and General Directions (TSRGD) do not permit the use of 5mph roundels as enforceable terminal or repeater signs on public highways, and local councils cannot enact a Traffic Regulation Order (TRO) for a 5mph limit on public roads.

For private land, 5mph zones are treated as advisory or contractual. Ignoring a 5mph speed limit could lead to civil liability or breach of property rules if an accident occurs. 5mph signage on private property can form a contract with drivers if explicitly mentioned on entry signs managed under a code of practice, such as by the British Parking Association (BPA). For commercial parking lots, warehouses and industrial estates, 5mph signage is governed by the Health and Safety Executive (HSE).

If speed bumps are used alongside this speed roundel, UK Highways Regulations under the Highways (Road Humps) Regulations 1999 state that speed bumps for enforcement should have a maximum height between 25mm and 100mm and a maximum gradient of 1:10. Guidelines suggest pairing 5mph signs with physical measures because drivers frequently ignore them due to their lack of statutory legal backing.

Who It’s For

Ideal for:

• Car park operators and facility managers

• Shopping centre and retail complex owners

• Industrial site and warehouse facility managers

• Educational institution car park administrators

• Private road and gated site managers

• Commercial parking lots where pedestrians and vehicles share the same space

• Sites using car park directional arrows for clearer traffic flow

5mph speed limit roundels are effective tools for conveying speed limits to motorists, particularly in areas like car parks. They are primarily used in high-risk zones where vehicles and pedestrians share the same space, including entrances, exits, crossings, loading areas, drop-off points and internal access roads.

If you want a professional, durable and highly visible 5mph speed control marking for a private site, this speed roundel fits your needs. For the strongest result, use it as part of a wider traffic management plan with upright 5mph signage, car park directional arrows and physical calming methods where appropriate.

Frequently Asked Questions

How long do 5mph speed roundels last?
They are built with thermoplastic material for long-term performance, with typical durability of around 3–5 years under normal traffic conditions. Service life depends on traffic volume, surface condition, weather exposure and installation quality.

Can I install these myself?
Professional installation is recommended because the product uses heat-applied thermoplastic technology. Correct surface preparation, heating and bonding are essential for proper adhesion and long-lasting results.

Do they work with existing car park markings?
Yes. The 5mph option is especially suited to layouts that already include car park directional arrows, bay markings, pedestrian routes and entry signage. It helps reinforce the speed limits motorists should follow as they move through the site.

What sizes are most popular?
Smaller sizes such as 600mm x 600mm and 1200mm x 1200mm are useful for compact car parks, internal routes and lower-traffic areas. Larger elongated options, up to 7600mm x 1500mm, are better for entrances, longer approaches and areas where the marking must be legible from farther away.

Are they visible in all weather?
The tri-colour red, white and black design provides strong daytime contrast, while thermoplastic materials used for road markings often include reflective components to enhance visibility and safety in all weather conditions.

Are 5mph roundels legally enforceable?
No. 5mph speed roundels and signs in the UK are advisory on private property and cannot be legally enforced under public traffic laws. On private land, however, clear entry terms and site rules may create contractual obligations, and ignoring them could matter if an accident occurs.
