The Truth About Speed Bumps: Risks and Precautions

Speed bumps are a common sight on many roads, particularly in residential areas and school zones. While they are designed to reduce speeding and improve safety, these bumps can have detrimental effects on your car if not approached with caution. In this article, we will explore the potential risks associated with speed bumps and share essential precautions to keep your vehicle in good condition.

Understanding the Risks

Speed bumps, also known as speed humps, are raised sections of road that force drivers to slow down. While many people see them as a necessary safety measure, they can indeed be harmful to your car if not navigated properly. The shape and placement of speed bumps are key factors in determining the impact they have on your vehicle.

Damages Caused by Speed Bumps

The shape of the bump can significantly affect the damage it causes. Smoothly shaped bumps generally require drivers to reduce their speed to a minimum, which helps minimize wear and tear. However, square-shaped bumps can be particularly problematic, regardless of speed. Continuous contact with these bumps can lead to various issues, including damage to the suspension, tires, and wheels.

Personal Experiences and Warnings

Take, for example, the story of a colleague who worked on a campus with speed bumps on the right side, leaving a flat section of road for bicycles. After a few years, the left side suspension began to wear out, and even his mother's car fell victim to similar issues. While these repairs were not excessively expensive, the potential for severe damage, such as a broken suspension or unattached wheel, highlights the seriousness of the issue.

Causes for Suspension Damage

The introduction of speed bumps has led to an increase in suspension damage. According to a local garage, it was almost unheard of for front springs to break until the installation of speed bumps. Now, this is becoming a common repair, emphasizing the importance of proper driving techniques.

Speed and Safety Considerations

For small cars with low suspension, speed bumps can be particularly dangerous. If your vehicle does not have a good under tray fitted, the oil sump can be damaged by constant impact. Additionally, it is crucial to respect the speed limit. When entering or leaving a neighborhood, you should slow down and consider the speed of the camera signals that might be hidden. Failure to do so can lead to costly repairs and potential safety hazards.

City-Specific Speed Bumps

Some cities have implemented speed bumps to address specific safety concerns. For instance, in the area where the author lives, the speed bumps are designed for a speed limit of 25 mph. However, drivers who do not observe the speed limit and cross the bump at higher speeds, like 25 mph when it should be at 10 mph, are putting their cars at risk. An incident involving a colleague who hit a poorly marked bump at 25 mph caused a spring to break under the front of the car, resulting in a repair bill of $800, including towing and replacement.

Conclusion

While speed bumps are an essential tool for enhancing road safety, particularly in residential and school areas, they can pose significant risks to your vehicle if not approached with the right mindset. Slow down, stay aware of your surroundings, and follow speed limits to minimize the impact of these road features on your car.
