When spaced and arranged strategically, road humps can effectively manage traffic flow and prevent traffic jams. They maintain road safety and vehicular order. Also, the speed hump installation procedure is easy. If you have a rubber or plastic speed hump, you can install it on your own.

A speed hump can make people follow the rules related to speed limits. So there is no need to make traffic police officers monitor vehicles for the same purpose because the tool alone can do that. Due to this reason, road humps are often called “the sleeping policemen.”


Cons of a speed hump

A speed hump makes emergency vehicles like an ambulance or fire truck slow down like other vehicles. It causes emergency-response delays. What’s more, it can prevent the normal flow of snowwater and affect drainage negatively.

Road humps also get hidden under snow during winters. As a result, drivers do not see them and drive over them at high speed, leading to surprise and inconvenience.

They damage vehicles’ internal parts and tires when they accidentally drive over them at high acceleration. However, experts believe that if people take necessary precautions, they can avoid these disadvantages.

There are three main materials of road humps that manufacturers use. These materials are rubber, recycled plastic, and concrete. Concrete road humps are very hard and inflexible. They neither compress like rubber nor absorb the impact like plastic. Due to this, they damage vehicles when they drive over them at high speed.

In contrast, rubber and plastic are not as hard as concrete, so they cause only a little damage to motor-vehicle tires. If you are concerned about your vehicle’s health, you should select a rubber speed hump for your parking lot or neighbourhood.
