What is a speed hump's effect on overtaking?

A speed hump serves several important purposes related to road safety and traffic management. Its primary function is to slow down vehicles, which creates a safer environment for pedestrians and reduces the likelihood of accidents. When it comes to overtaking, speed humps fundamentally change the dynamics of how vehicles can maneuver in those areas.

As vehicles approach a speed hump, they must reduce their speed significantly to navigate it safely, which makes overtaking impractical or unsafe. The design of speed humps means that drivers are generally required to slow down and maintain a level of caution, making it difficult to safely pass another vehicle. Additionally, the presence of a speed hump may impede visibility and create conditions where overtaking could lead to dangerous situations.

Thus, the presence of a speed hump effectively prohibits overtaking in the immediate vicinity, reinforcing safe driving behaviors and reducing the risk of collisions.
