Speed bumps and speed humps are both traffic calming devices, but they serve different purposes. This guide explains the differences and helps you choose correctly.
The Key Difference
Speed bumps are short, abrupt — 25–100mm high and 300–600mm long. They force vehicles to 5–10 mph. Designed for car parks and private roads.
Speed humps are longer, gentler — 75mm high and 3.5–4 metres long. They reduce speed to 15–25 mph. Used on public roads and school zones.
| Feature | Speed Bump | Speed Hump |
|---|---|---|
| Height | 25–100mm | 75mm |
| Length | 300–600mm | 3.5–4m |
| Target Speed | 5–10 mph | 15–25 mph |
| Location | Car parks, private | Public roads |
| Installation | Bolt-down modular | Asphalt construction |
When to Use Speed Bumps
- Car parks — supermarkets, retail, offices, hospitals
- Warehouse yards — where pedestrians mix with vehicles
- Private estate roads — residential, holiday parks
- School grounds — drop-off zones
Modular rubber speed bumps bolt down to tarmac or concrete, need no planning permission on private land, and install in under an hour.
Materials and Durability
Rubber: Made from recycled rubber, UV-resistant, built-in reflective strips. Lifespan 5–10 years.
Plastic/PVC: Lightweight, cheaper, less durable. For light-traffic areas.
Installation Guide
- Clean the surface thoroughly
- Mark position with chalk lines
- Lay out end caps and mid-sections
- Drill through pre-marked holes
- Insert expansion anchors and bolt down
Two people with a drill: 30–45 minutes per bump.
Legal Requirements
Private land: No planning permission needed. Must meet health and safety obligations.
Public roads: Requires local authority approval under Highways Act 1980 and Road Humps Regulations 1999.
