Vehicle and pedestrian safety in the UK is ensured by propping speed bumps and speed cushions. There are specific rules for the use of this equipment as applied by every state.

Whether in parks or industrial areas, speed bumps are utilized in all traffic lanes and areas. The main purpose of installing speed bumps is to fend off traffic mishaps and discomfort, and to secure the safety of pedestrians.

All high traffic areas in the UK have to make use of Speed Bumps, and there are particular rules and regulations for this, along with their installation. Speed limits have to be maintained.

Below are salient details about the speed bump regulations as required by the Department of Transportation in the UK.

Why Are Speed Bumps Regulations In The UK Important?

Speed Bump Regulations in the UK

Pedestrians have to be safe as they pass through high-risk roads, and speed bumps have been effective pertaining to this, as revealed by UK traffic controls. When you install speed bumps, they are quite productive in calming traffic.

Speed bumps have been aggressively designed to be highly effective in decelerating the average speed of vehicles while on the road, pavement, crosswalk or roadway.

Regardless of their design and specifications, however, the UK government has mandated that road bumps installed on the road should be made of rubber or plastic so that they do not damage the local area as they change the speed limits of vehicles.

The placement and location of speed bumps is highly crucial. Speed bumps are important in distinctly crowded areas together with speed breakers. This equipment reduces the speed of vehicles by 2 to 5 mph.

In what areas are speed bumps installed according to regulations?

  • Ramps
  • Car parks
  • Entrance areas
  • Private driveways

    Mandated Regulations About Speed Bumps In The UK

    There are a number of rules, guidelines and regulations when it comes to the DIY installation of speed brakes, among other traffic calming and control devices and measures in the UK. Such directives are assigned by the state government and the federal highway administration.

    Then again, the regulations are much more different regarding the laying out of speed bumps in private roads than highways.

    It is through the Department of Transport that the UK government regulates the use and installation of speed bumps in highways and common road paths.

    For the most part, it is the England and Wales Highway Regulations of 1999 that governs the optimal utilization of speed bumps on private roads.

    There are numerous clauses and sub-clauses for the reduction of traffic flow indicated in these regulations. Nevertheless, its basic idea is to avoid installing speed bumps on slow zones and private roads.

    How Should Speed Bumps Be Used On Private Property?

    Rules and regulations imposed by the local council are to be followed in relation to the installation of any traffic related initiatives on the private land. This is the advice of government authorities in the United Kingdom.

    Temporary courses of actions installed on private lands should be easy to remove when necessary, including the city streets.

    The Highways (Road Bumps) Regulations 1999 also governs the imposition of regulations for the installation of speed bumps. Part of this mandate is the restriction of improperly using and installing speed bumps.

    Speed Bump Specifications and Requirements

    Local authorities are required to follow the important requirements and traffic laws at the time of putting the rubber speed bumps in place:

    • Speed bumps should be fitted on roads that have a speed limit of a maximum of 30 mph.
    • Speed bumps are to be affixed for an area to have a 20 mph speed limit and where there are street lights and low traffic.
    • Areas that are well-lighted with the vigorous speed of vehicles are especially the main areas where speed bumps and humps should be installed.
    • The installation of the elevated section of speed bumps with a 20 mph speed limit should accord with the pertinent regulations implemented by the highway authority.
    • It has to be ensured that the necessary signage is available from the highway authorities while 20 mph speed bumps are installed.
    • So that traffic mishaps and accidents can be prevented on private roads, severe speed bumps with 10 mph speed limit should be installed.
    • Dimensions should be accurately observed while the speed bumps are laid out.
    • Road markings and construction signs should be in place during a speed hump installation.

      The Fundamental Regulations For Speed Bumps In The UK

      The Highways (Road Humps) Regulations 1999 have issued traffic laws and regulations citing that all guides for the installation and utilization of speed breakers on UK roads have to follow the rules of England and Wales.

      This law has been imposed for the predominant reason of preventing the improper usage of speed bumps.

      What's the Difference Between Speed Bumps and Speed Humps?

      While both "speed bumps" and "speed humps" aim to regulate traffic flow, they achieve this in slightly different ways. Speed bumps are typically shorter in length but possess a steeper incline. This abrupt rise forces drivers to slow down significantly, often to a near crawl, to avoid bottoming out their vehicles. They're ideal for areas with very low-speed limits, such as private car parks or school zones.

      Speed humps, on the other hand, are gentler inclines that stretch over a longer distance. This allows drivers to maintain a slightly higher speed (around 10-15 mph) while still encouraging them to slow down. Their smoother profile makes them suitable for traffic calming measures in residential areas or on roads with moderate speed limits.

      How Often Do Speed Bumps Need to be Spaced Out?

      The optimal spacing between speed bumps in the UK depends on several factors, including the desired traffic speed reduction and the type of road. However, there are some general guidelines to follow.

      For speed bumps in areas with very low-speed limits (around five mph), a spacing of 20 to 150 meters is typically recommended. The average spacing is generally about 70 meters; this close spacing ensures a significant reduction in speed and discourages any attempts to speed between the bumps. 

      The exact spacing of speed bumps or humps or other speed cushions should be determined by a qualified traffic engineer who can consider all the specific factors at play. 

      How High Should Speed Bumps Be?

      Speed bump height in the UK is strictly regulated to ensure both effectiveness in traffic calming and safety for vehicles. According to Highways Regulations, speed bumps must be within a specific range: no lower than 25 millimetres (1 inch) and no higher than 100 millimetres (4 inches). 

      This height restriction serves a dual purpose. Speed bumps that are too low might not sufficiently deter drivers, while excessively high ones could damage vehicles with low ground clearance or create a hazard for emergency service vehicles.

      It's important to remember that speed bump height isn't the only factor influencing their effectiveness. The surrounding signage, road markings, and the total length of the speed bump also play a role in traffic control.

      Am I Allowed to Install Speed Bumps?

      While speed bumps can be a valuable tool for traffic calming, their installation isn't always straightforward. There are regulations in place to ensure they are used appropriately and don't create unnecessary hazards, especially for emergency vehicles.

      Generally, in the UK, you cannot install speed bumps on public roads without permission from your local highway authority. This process typically involves submitting a formal request and demonstrating a need for traffic calming measures. 

      However, you might be able to install speed bumps on private property, such as a driveway or car park. Even in these cases, it's advisable to check with your local council for any restrictions or specific requirements that might apply. 

      Consulting a professional for guidance on the regulations and appropriate installation procedures is highly recommended.

      Consult Pertinent Authorities In The Area

      the UK, the chief office of the police of the local council has to first be consulted. Consultants that need to be conferred with include the local fire brigade and the ambulance services.

      These local area authorities should be consulted for the important reason of preventing the propped up speed bumps along with street signs from obstructing the local routes of service vehicles. Additional considerations are the intelligent transportation systems and highway signs.

      There are salient sections of these regulations.

      • Legal organizations that use the roads should be contacted so that they will know the warning signs.
      • Among these legal organizations are traders, buses, maintenance services and waste collection groups.
      • Speed humps should be set-up on private roads in local areas along with railroad crossing areas.
      • Residents in the work zone should be consulted, especially if they use the road together with the local organizations.


        These are the laws and regulations issued by authorities for speed bumps in the UK.

        Some of these laws accord with traffic signs and the use of lighting together with the speed bumps. The government thus imposes these laws in connection with the laying out of speed bumps on the road.

        Commercial and domestic speed bumps should be appropriately checked so that traffic all around the UK will be controlled.
