It’s no surprise that 22% of people have had their cars damaged because of speed bumps. Launched in 1983 to slow drivers down, now there are 29,000 speed bumps in the UK! We’ve had lots of discussions with drivers about speed bumps and most of them having nothing good to say about them – (not surprisingly). Drivers made the following comments which we have summarised below.

  • Speed – when you see a speed bump you reduce your speed for a few seconds and then actually speed up quickly, more than you would if you were just driving along the road. So speed bumps don’t work!
  • Car damage – they cause damage to our cars. The damage ranged from issues with the suspension to damage to bodywork.
  • Environment – they are bad for the environment as drivers to speed up and slow down, this could have an impact on air quality.
  • Signs – there should be clearer signs to warn drivers there is a speed bump.

Types of Speed Bumps

There are actually four different types of speed bumps: a speed bump, a speed hump, a speed cushion, and a speed table.

Speed Bumps

Speed Bumps are abruptly raised areas in the road, they are rounded and are usually from 2 to 6 inches high and can be 6 inches to up to 3 ft long. They are designed so drivers to go over them at five miles per hour or less. For this reason, they are usually found in private roads, parking lots and residential streets as drivers would already be driving at a low speed. If drivers go over speed bumps at a higher speed this would cause damage to their vehicles. So maybe it’s not the speed bumps that are causing damage to the vehicle as we mentioned above, but rather the speed that drivers are going over the bumps!

Speed Humps

Speed humps are more rounded, raised areas placed across the roadway. They are usually 3 to 4 inches high and 10 to 14 feet long. They actually create a gentle rocking motion to vehicles would usually slow down to 15-20 mph over the speed humps. If they are spaced out along the road then you can go over them at 25 to 30 mph safely.

Speed Cushions

Speed cushions are several small speed humps that go across the width of the road with spaces between them. They are generally placed in a series across a roadway resembling a split speed hump. They are designed to force cars to slow down as they ride with one or both wheels on the humps.

Speed Tables

Speed tables are flat-topped speed humps often constructed with brick or other textured materials on the flat section. Speed tables are typically long enough for the entire wheelbase of a passenger car to rest on the flat section. They are good for locations where low speeds are desired but a somewhat smooth ride is needed for larger vehicles.

Speed Bumps Regulations

There are speed bump regulations which are very specific, we will just summarise the interesting parts here!

  • Location – there are specific regulations to do with where speed bumps can be located. Such as they shouldn’t be near a railway level crossing. They can’t be positioned within 25m of bridges or tunnels.
  • Dimensions – there are specific dimensions that are permitted. Height should be between 25mm and 100mm. The minimum length should be 900mm.Whether drivers like speed bumps or not, they are not going anywhere. It would be too costly to remove them. Residents usually like them as drivers are forced to slow down. The best thing to do when you see a sign for a speed bump is to slow down to prevent any damage to your vehicle!If you need recovery for your vehicle call 01184 492443 our 24-hour breakdown and recovery will be happy to assist you.
