How does the adhesion of motor vehicles change with speed when driving on wet roads?
1 Answers
When driving on wet roads, the adhesion of motor vehicles decreases sharply as speed increases. Here are some precautions for driving in rainy weather: 1. Reduce speed: Regardless of road width or surface conditions, slow down when driving in the rain, always pay attention to the distance between vehicles ahead and behind, and be mentally prepared to take various emergency measures. Visibility is low in rainy weather, and the field of vision is poor. The emergency performance of vehicles, such as braking distance, will also be reduced, so it is necessary to slow down in advance, leaving sufficient time and space to handle situations to ensure safety. 2. Maintain distance: When driving in the rain, visibility is obstructed, so it is important to maintain a safe distance between vehicles, constantly observe the distance between vehicles ahead and behind, and increase the safety distance. Especially stay away from large vehicles, as they can block your view; moreover, large vehicles may pass through waterlogged areas that smaller vehicles cannot, and they are prone to splashing water waves, which can interfere with the driving of smaller vehicles. 3. Use fog lights when driving in the rain: Make full use of fog lights to enhance driving safety in rainy weather. If necessary, turn on the hazard warning lights so that vehicles behind can always be aware of the situation ahead. 4. Do not restart after stalling: In heavy rain or stormy weather, some road sections may become severely waterlogged in a very short time. If you have to drive through water, use a low gear and pass at a constant speed. If the vehicle stalls while moving, do not attempt to restart it. Blindly restarting may cause the engine to be scrapped. After the vehicle stalls, contact a professional repair shop promptly. Only after the maintenance personnel have inspected the vehicle on-site and confirmed that there are no problems can the vehicle be restarted.
