Driving down a residential street and suddenly hitting a bump that slows your vehicle to a crawl can be an annoying experience. Those bumps, or speed humps, have become increasingly popular in cities around the world as a way of slowing drivers down and making roads safer. But are they really worth the trouble?

In this article, we’ll explore the pros and cons of speed humps and try to answer whether they are a useful tool for regulating traffic or just another pain for motorists. We’ll look at what speed humps are, how they work, their advantages and disadvantages, their legal status, and more.

By the end of this article, you will have a better understanding of the benefits and drawbacks of speed humps so you can make an informed decision about whether they are worth the trouble.

What are Speed Humps?

Speed humps (or speed bumps as they are sometimes called) are raised surfaces placed across roads, parking lots, or driveways. The purpose of a speed hump is to reduce the speed of vehicles passing over them and make those areas safer for pedestrians. They are generally composed of asphalt or concrete and may be paired with a speed limit sign. Speed humps tend to be 12-15 inches tall, 3-4 feet wide, and about 15-25 feet long. They are usually spaced about 100 feet apart so that vehicles must slow down as they approach each one.

Speed humps can also be accompanied by traffic calming devices such as chicanes, islands, and roundabouts. These devices help direct traffic on narrow roads while discouraging speeding by forcing drivers to slow down and maneuver around the obstacles. As an added bonus, they provide visual aesthetic benefits as well: they beautify the area while reducing vehicle noise levels due to their solid construction. Additionally, speed humps have been found to reduce driver distraction since they eliminate the need for drivers to frequently adjust their speed when navigating narrow roads.

Finally, speed humps provide additional safety benefits for cyclists and pedestrians. By slowing down vehicles in residential areas, there is less likelihood of accidents occurring due to reckless driving. Although cyclists must take extra care when crossing speed humps due to the height difference between them and regular roads, these bumps can still provide increased safety in areas where pedestrians frequently cross paths with cars.

Advantages and Disadvantages of Speed Humps

Speed humps, also known as speed bumps, are raised features on roads designed to slow down traffic. They are used in residential neighborhoods and near schools, parks and other areas where people may be present. While they are frequently seen in many communities around the world, there is much debate over their effectiveness and whether they truly make an area safer or simply cause unnecessary vehicle damage. In order to weigh the pros and cons of speed humps, it is important to understand how they work and their various advantages and disadvantages.


One of the primary advantages of speed humps is that they can be used to slow down traffic in areas where pedestrians, cyclists or schoolchildren are present. By decreasing the speed of vehicles traveling through these zones, the risk of accidents is greatly reduced which makes it safer for everyone using the roads. In addition to this, speed humps also help reduce noise levels due to decreased traffic speeds which can make living in a neighborhood more comfortable for those living close by.


Unfortunately, speed humps also have some drawbacks that need to be considered before installing them on local roads. For example, if a vehicle is moving too fast when approaching a speed hump, there is potential for bottom-out damage which can lead to expensive repairs. This can be particularly problematic as it might discourage people from driving through that area altogether leading to increased congestion elsewhere on the roads. In addition to this, some research has suggested that drivers may become complacent when passing over well-known speed humps meaning they do not always take necessary caution when passing them by.

In conclusion, while speed bumps offer some benefits in terms of slowing down vehicles in certain areas and reducing noise levels; it is important to consider the potential drawbacks such as bottom-out damage and driver complacency before installing them on local roads.

Advantages of Speed Humps

Speed humps are a popular traffic calming measure that have been used for decades to regulate vehicle speeds and improve safety on residential roads and in parking lots. Speed humps come with many advantages, including:

1. Reduced Speeds: Speed humps are effective at reducing speeds to the posted speed limit or lower, creating a safer environment for drivers, pedestrians, and cyclists alike. Drivers will often slow down if they see a speed hump ahead of them, reducing their overall speed over the entire stretch of road.

2. Enhanced Visibility: Speed humps also serve to make drivers more aware of their surroundings. By forcing them to slow down slightly, it gives them more time to observe the road and its conditions before continuing on. This enhanced visibility can help prevent accidents, since drivers are more likely to spot potential hazards sooner when traveling at slower speeds.

3. Improved Pedestrian Safety: Slower speeds also help protect pedestrians from getting hit by vehicles speeding through intersections and crosswalks. Drivers are more likely to stop or yield for pedestrians when traveling at reduced speeds, since they have more time to react and process what is going on around them.

4. Cost-Effectiveness: One of the main advantages of speed humps is their cost-effectiveness compared to other traffic control measures, such as road widening projects or additional signage. Speed humps require minimal maintenance and can be installed quickly and cheaply on existing roads or in parking lots.

Disadvantages of Speed Humps

Speed humps are an effective way to reduce speed and increase safety on roads, but they also bring a number of disadvantages.

One of the primary concerns about speed humps is their impact on vehicle suspension and other components. Driving over speed humps can cause serious wear and tear on cars, including broken axles or suspension failure, particularly in smaller vehicles. In some cases, sharp turns required after crossing a speed hump can also be difficult for larger vehicles to maneuver.

Not only are speed humps expensive to install, but they can also be costly to maintain over time. The cost of repair and replacement due to damage incurred by drivers and snow plows can add up quickly. In addition, many drivers do not respond positively to the installation of speed humps; it inhibits their ability to drive at a desired speed and can also cause additional noise pollution due to increased braking and acceleration.

Finally, speed humps are not suitable for all roads or even all sections of one road; they should only be installed in areas with low volumes of traffic or where the posted speed limit needs to be strictly enforced. As such, they tend not to have much effect on speeding in large cities where high volumes of traffic make implementing these measures difficult.


When it comes to speed humps, the debate between those who think they are effective and those who don’t often centers on their practicality. On the one hand, speed humps can be viewed as an effective way to reduce vehicle speeds, making them safer for pedestrians and cyclists in residential neighborhoods. They can also provide a psychological deterrent that could reduce reckless driving. On the other hand, they can be expensive to install and maintain and may not be appropriate for every type of road. Additionally, there is some evidence that speed humps can cause the engines of vehicles to labor while going over them, reducing fuel efficiency and potentially causing damage.

In conclusion, when deciding whether speed humps are worth the trouble or not, it is important to consider local traffic conditions and the type of road being targeted for installation. Speed humps may have their pros and cons but depending on the situation, they could still be an effective solution for reducing speeding in residential areas.
