What’s the purpose of road humps?
Is it speed hump or road hump?

There’s often confusion between “speed bumps” and “road humps,” but they have some subtle differences:


  • Speed bump: Technically, a speed bump is a specific type of traffic calming device with a steeper incline and shorter length compared to a road hump. They’re designed to slow vehicles down to very low speeds (2-5 mph) and are often used in private driveways or parking lots.
  • Road hump: This is a broader term encompassing various traffic calming devices with gentle inclines and longer lengths (typically 10-15 feet). They aim to slow traffic to moderate speeds (10-15 mph) and are commonly found on residential streets, school zones, and near crosswalks.


Both bumps and humps aim to improve road safety by:

  • Reducing vehicle speeds: This protects pedestrians, cyclists, and children who are more vulnerable to traffic accidents.
  • Calming traffic: They encourage slower, more predictable driving, making streets safer and more pleasant for everyone.

Which term to use:

In everyday language, “road hump” is more commonly used than “speed bump” since most traffic calming devices on public roads fall under the “hump” category. However, if you’re referring to a very specific device with a steep incline, “speed bump” might be more accurate.

Remember, the main point is that both terms generally refer to raised features on roads designed to slow down traffic and improve safety.

Road humps are also commonly known by various names, including speed humps, speed bumps, traffic calming devices, or simply road bumps. The terminology may vary depending on regional preferences or specific regulations.

The terms “bumps” and “humps” are often used interchangeably, but some distinctions may exist based on local conventions. In general, a “speed bump” is typically shorter and broader, causing a more sudden and pronounced jolt when a vehicle passes over it. On the other hand, a “speed hump” is usually longer and flatter, designed to slow down vehicles more gradually.

The primary purpose of road humps is to control and reduce vehicle speeds in specific areas, such as residential zones, school zones, or areas with high pedestrian traffic. They are a form of traffic calming measure implemented to enhance safety by discouraging speeding and promoting a slower, more controlled flow of traffic. Road humps contribute to creating safer environments for pedestrians and residents, reducing the risk of accidents and promoting a more comfortable living space.

The terms “speed hump” and “road hump” are often used interchangeably. Different regions or countries may have preferences for one term over the other, but both generally refer to the same type of traffic calming device.
