Sinusoidal – This type of speed bump is very similar to a round top hump the only difference is the incline towards the hump isn’t as steep. This hump was originally developed so that cyclists can travel over them more comfortably.
Speed tables/flat top/raised junction – These are a longer and flatter version of a speed bump. When travelling over this type of speed bump, it elevates the whole vehicle at once. This type of traffic calming measure is usually used on crossings. A speed table helps slow traffic down but doesn’t impact the flow of traffic.
Do speed bumps work?
Many studies have shown that speed bumps can reduce accidents by around 44%, they deter excessive speeding which then results in fewer accidents.
Certain speed deterrents work better than others and it is seen that speed humps do not slow motor vehicle traffic as much as speed tables, however, they are more effective than speed cushions.
How should you drive over speed bumps?
The first thing to take into consideration is the speed of your approach. Drop your speed down to at least 10mph if not lower before going over a speed bump. Depending on the height of the bump you may want to reduce your speed further.
The best way to go over a speed bump is to take it slow! Try to avoid braking when you are going over the bump. The straighter your vehicle is while going over the speed bump, the better to avoid scraping the underside of your car.
Do speed bumps damage my car?
Similarly to when potholes damage your vehicle, going over a speed bump too fast can cause damage to your vehicle. The main issues caused by speed bumps are suspension and tyre issues .
Cars that sit lower to the ground could also experience damage to the bottom of the car. This could affect the exhaust so ensure you are driving at an appropriate speed over the speed bump.
Constantly driving over speed bumps at high speed can eventually take its toll on your vehicle. It can cause rattles and squeaks, loosening, and even dropping parts.
