All Speed Bumps


Speed bumps and speed humps have the same meaning and are used throughout the UK to slow traffic down. Our selection at Pittman has options to slow traffic to approximately 5mph, 10mph or 15mph. Please choose from our selection to slow down cars or HGVs on any street or property. Our speed humps offer super-quick installation, and sections are easy to replace when needed.

Talk to our experts on  020 3773 5397 or sales@pittmantraffic.co.uk to help you whether you need a sleeping policeman, a speed cushion to reduce speeds in urban areas or a speed ramp to slow cars and HGVs.

Speed bumps help reduce the speed of cars, trucks, and vans on roads, significantly reducing traffic accidents. However, driving over the bumps too fast will result in a hard, uncomfortable drive. Generally speed humps are made from concrete, asphalt, plastic or metal.

How to choose the right speed bump

To choose the proper speed bump, you need to consider:

  • The kind of vehicles will be travelling over the speed bump? Will it need to cater to trucks, buses, or cars? Do emergency vehicles use the road regularly, and can they pass over the bump with little or no restriction to their speed? Different vehicles have different requirements, so make sure you know which vehicles are on the road.


  • What is the ideal speed for traffic in the area? The height and width of the bump will have a significant difference in the impact to speed. For example, a 30mm speed hump generally allows vehicles to pass over the ramp at 15mph in comfort. In contrast, a 75mm ramp will reduce vehicle speeds dramatically and should only be used where there is a significant risk to pedestrians.


  • What type of road surface is the speed bump being installed on? The road surface may affect the fixings you will use for your road bump. Concrete and asphalt roads may need different fixings, while some suppliers (including Pittman) use universal fixtures to suit the majority of road surfaces.

Types of Speed Humps

Speed Bumps
Immediate bump used to slow vehicle or HGV traffic. Ranges from 30mm to 75mm high. It causes a quick bump to encourage drivers to slow down. Driving over a speed bump too fast will result in an uncomfortable drive for drivers. Severe speeding may also damage the car.

Speed Cushions
A less severe bump is used to slow vehicles to a reasonable speed but keeps traffic flowing. They are generally installed with gaps in between to allow larger emergency vehicle axles to get around the cushions without hindering response times, typically used in urban settings.

Speed Tables
Speed tables are the largest traffic calming option from front to back. The "table" style layout provides an excellent traffic calming option for cities or towns. The design offers a gentle bump that encourages drivers to slow down to reasonable speeds. However, the speed table will allow general traffic to flow, only slowing vehicles on approach to pedestrian crossings. The speed table is also often used as a pedestrian crossing for public spaces.

Kerb Ramps
Kerb ramps are installed against kerbs to provide easier access for cars. Kerb ramps are commonly installed where the kerbs are too high for vehicles to access. The ramps can be used permanently or temporarily as needed.

Rumble Strips
Rumble strips are shorter humps that provide physical and audible warnings for drivers to slow down. While they are less physically imposing on drivers, they are an excellent means to remind drivers to slow down on the approach to the pedestrian crossings, junctions or entrances. When the drivers feel and hear the plastic safety rumble strip, they will be encouraged to slow their cars considerably. Install the rumble strips before regular speed humps to reduce speeds before they reach the area.

For a quick guide on choosing the right speed bump see a few choices here: 

  • JSP Ridgeback Speed Bump Kit 50mm – slows traffic to approximately 10mph, ideal for cars and light vehicle use
  • JSP Ridgeback Speed Bump Kit 75mm – slows traffic to approximately 5mph, ideal for cars and HGVs. Use where there is an immediate danger to pedestrians.
  • XPT Berlin Speed Cushion – Slows traffic to approximately 20mph, suitable for cars and HGVs. Ideal for towns and cities where traffic needs to flow. Allows emergency vehicles to pass through largely unhindered due to the shape and profile.

  • XPT-Modular System Speed Table – slows traffic to approximately 20mph, gradual bump instead of a sharp, immediate bump. Allows city traffic to maintain a steady flow and doesn’t slow vehicles to a near-stop. Speed tables are often used to form a pedestrian crossing.

What are the advantages of modular rubber speed bumps?

There are many advantages to installing modular rubber speed bumps:

  • Precise moulding of sections provides a uniform height and design of the bump
  • More cost-effective in terms of labour and materials
  • Easier installation than concrete or tarmac options
  • Easier to replace sections if they become damaged or worn
  • Less disruptive to the area during installation – can be used immediately
  • Better visibility than most concrete or tarmac versions
  • Manufactured from recycled material

How are speed bumps installed?

To install speed bumps, you will need precise measurements of the area and the bump suited. The modular sections allow for fast installation on site. 

To install, mark the area for each section (using the pre-drilled holes) and drill the required depth for the fixing. Next, insert the needed piece (end-cap or mid-section) and tighten it. Once installed, the speed bumps can be used immediately. Ensure all works are completed following safety guidelines.

What is the lifespan of rubber speed ramps?

When installed correctly, rubber speed ramps can last for many years. However, their lifespan depends on the installation and the type & volume of traffic on the road. Call the team at Pittman to help choose the best speed bump for the job.

Rubber can maintain better shape than concrete over time. Modular sections are also easily replaced if they become worn or damaged. If installing multiple speed bumps, it is advised that the layout includes at least one vehicle’s length between them.

How fast can you drive over a speed bump?

The height and width of the speed bump will determine how fast you can drive over it. A 50mm bump will slow vehicles to around 10mph. A higher 75mm hump will cause drivers to slow to around 5mph. A speed cushion can offer an easier, more gradual bump – they generally slow traffic to 15-20 mph. These kinds of bumps are better suited to city and town environments. 

Is it illegal to avoid speed bumps?
Speed bumps should not be avoided. Drivers should not swerve or enter into other lanes to avoid the bump. In order to deal with the speed bump drivers should slow to the appropriate traffic speed. The spaces at the centre or sides of the speed humps are for drainage and help to keep the surface clear of standing water or snow.

What is the difference between speed bumps and speed humps?

Speed bumps are generally more severe and provide an immediate bump, where speed humps are less severe at lower speeds.

Speed Bumps:

  • Instant bump designed to slow traffic down instantly
  • Effective for controlling speeds at low traffic volumes
  • Shorter from front to back
  • Not ideal for emergency vehicles and coaches
  • Common in car parks and private car parking premises
  • Slows traffic to approximately 5-10mph

Speed Humps:

  • Gradual bumps that are designed to slow traffic to a considerable speed
  • Effective for controlling speeds at high traffic volumes
  • Longer from front to back
  • Ideal for emergency vehicles and coaches
  • Common on public roads
  • Slows traffic to approximately 15-20mph.


What is a sleeping policeman?

A sleeping policeman is a common name for a road bump or speed hump within the UK. As the bump helps to control traffic speed, it is compared to a policeman's job. The 'sleeping' part relates to the bump lying across the road. 
Other names for sleeping policeman are speed ramps, speed humps, judder bars, and lying-down policemen.

What is traffic calming?

Traffic calming is a popular term for speed control. Traffic calming refers to the reduction of vehicle speed. Speed bumps, speed humps, and speed cushions are all considered key traffic calming and speed control devices.

Traffic calming is a common term used among government bodies and councils. Traffic calming aims to decrease vehicle speeds to reduce the risk of traffic accidents. Calming involves vehicles, cyclists and pedestrians. 

Speed bump sign requirements

Use speed bump signs with all speed bump setups. The signs indicate that bumps are in place and should slow down accordingly. These signs may also be combined with speed signs or road markings to make the message very clear to drivers.

Typical signs will include a speed hump symbol and text. For example, the text may read "ramps ahead" or "speed bumps ahead". The standard UK design for a speed hump sign is a triangular format with a black bump symbol, white background and red outline.

Any speed bump signage should be installed where drivers will easily see it. Standard installation includes mounting to nearby sign poles. Wall-mounted signs could also be used depending on the area.
