Bumps are a common feature on Kenyan roads, mostly used to control the speed of motorists.
However, as you use major roads and highways, you may have seen different types of bumps with various variations, including size and shape.
Here are four types of bumps and the role they play.
Speed bumps
These are the most common types of bumps found on Kenyan roads. They are usually the tallest in terms of height.
Most of them usually range from 10 to 20 centimetres high.
Commonly found near shopping centres and areas where there is a lot of human activity.
They can also be placed next to hotspots where overspeeding has been cited as the major cause of accidents.
Speed tables
These bumps are flat at the top and longer in terms of width, mostly located next to junctions.
They are mostly found on highways where heavy vehicles such as trucks and emergency vehicles are frequent.
These bumps allow the vehicle to manoeuvre without causing any disruption to the vehicle.
They also enable the car to reduce its speed and, at the same time, move with ease. They can also act as zebra crossing spots.
Speed humps
These bumps are longer in terms of length and smaller in height as compared to normal speed bumps.
On the other hand, they resemble table bumps but are curvy at the top.
Speed humps are mostly found on roads in residential areas.
Rumble strips
They are patterns of groves placed on a section of a road, causing a vibration or rumbling effect when a motorist drives on them,
Commonly used to warn motorists of merging lanes. They can also be used to alert drivers to be aware of speed bumps.
In some instances, they force drivers to reduce their speeds, especially when approaching toll stations.
