Ultimate guide to speed bumps

Looking to purchase speed bumps? Or simply want to brush up on your knowledge using our helpful FAQs? Our detailed guide to speed bumps has you covered.

What is a speed bump?

Speed bumps are a traffic calming measure used to slow down the speed of vehicles. These are often used in residential or busy pedestrian areas, such as around schools. They can also be for worksites, or wherever traffic calming measures are required.

Speed bumps FAQs

Why do we have speed bumps?

Speed bumps, as well as other traffic calming measures such as speed cameras and speed control signs, are designed to slow down traffic – improving safety for drivers, pedestrians, passengers and other vehicles on the road.

How tall are speed bumps?

The average height of a speed bump is around 6.5 to 7.5cm, which is recommended by the government. However, in 1999, the Department for Transport set that speed bumps must be a minimum height of 2.5cm and maximum height of 10cm. This then means that drivers must slow down to a speed of around 5mph to navigate a speed bump without damage.

Who invented speed bumps?

Physicist, Arthur Holly Compton, invented ‘traffic control bumps’ in 1953, which are now known as speed bumps. He initially invented these to stop cars speeding when they drove past his university. However, traffic calming first appeared around 1906 in New Jersey, USA – when the average speed of an automobile reached 30mph.

How far apart should speed bumps be placed?

It’s recommended that speed bumps should be placed between 20 metres and 150 metres apart, however, the average spacing is normally around 70 metres apart. It should be noted that the spacing between speed bumps will influence the average speeds of the roads.

What’s the difference between speed bumps and speed humps?

Speed bumps are usually made of plastic or rubber, and are clearly marked with paint so drivers can spot them easily. They are usually as high as 10cm, and are typically used in parking lots, residential areas and private roads – as the height of the speed bump requires a significant reduction in speed.

Speed humps, on the other hand, are the large bumps which span the entire width of the road. Typically covered in tarmac, they appear to be more of a feature of the road. Although their maximum height is the same as speed bumps, typically, they’re not this tall – meaning speed reduction wouldn’t be quite as much as speed bumps.

Applying for speed bumps

Often, people wonder how to get speed bumps installed on their street in the UK. Applying for speed bumps is a process which will involve:

  • Organising your campaign
  • Determining whether speed humps are appropriate for your street
  • Communicating with your local council with your case of why your street should have speed humps
  • Getting your local council to act

For more information, visit your local council’s government website.

Guide to trench covers

Used most often in streetworks and to enable pedestrian access, trench covers are a safe solution to main accessibility – whether that’s on a pavement or on the road. But, which safety trench cover should you choose? And what are the different types of plastic trench covers?

What is a trench cover?

A trench cover is intended to cover bores, trenches and apertures. Plastic trench covers are typically used during construction, maintenance and repair works, and are suitable for a variety of uses – ranging from pedestrian and residential use, to driveway and construction. Safety trench covers are designed for maintaining accessibility to an area that has developed a trench or a bore, while keeping pedestrians and vehicles crossing over the trench as safe as possible.

  • LowPro 11/11 – anti-slide pedestrian board suitable for 1.6 tonnes vehicle over a 700mm trench.
  • 12/8 Safe Cover – anti-slide pedestrian board suitable for 2 tonnes vehicles over a 700mm trench.
  • 16/12 Safe Cover – driveway board suitable for 2 tonnes vehicles over a 900mm trench.

Which safety trench cover do I need?

When deciding which plastic trench cover you need, firstly, you must identify the size of your trench:

  • Up to 700mm
  • Up to 900mm
  • Up to 1200mm

Next, you will need to determine what kind of traffic will cross over the trench:

  • Pedestrians and light vehicles which might park on the kerb
  • Vehicles up to 3.5 tonnes
  • Vehicles on a carriageway, which can be up to 44 tonnes

Once you’ve determined these elements, you will then be able to identify what type of trench cover or road plate you need. That’s where our handy guide on trench covers comes in. Learn which type of temporary trench cover or road trench cover plate you need now.
