What is the function of speed limits on roads?

The function of speed limits on roads is primarily to set a maximum speed and improve safety. Speed limits are established based on various factors including road type, traffic conditions, and surrounding environments, which help to regulate the flow of traffic. By setting these maximum speeds, they aim to reduce the likelihood of accidents, allow for safer stopping distances, and generally promote a safer driving environment for all road users.

Higher speeds can lead to increased reaction times and reduce the driver's control over the vehicle. Speed limits therefore play a crucial role in ensuring that drivers maintain a pace that is manageable and safe for the given conditions. This is essential not only for drivers but also for pedestrians, cyclists, and other key road users, thereby enhancing overall safety on the roadways.
