What Are the Hazards of Taking a Turn at Speeds Exceeding 30?
1 Answers
The hazards of taking a turn at speeds exceeding 30 are introduced as follows: 1. Increased reaction distance: When a motor vehicle is traveling at 60 kilometers per hour, it generally takes about 0.7 to 1.0 seconds for an average person to react from realizing the danger to applying the brakes, with a reaction distance of approximately 17 meters (idle distance). When traveling at 120 kilometers per hour, the reaction distance increases to about 39 meters (idle distance), doubling the distance. As speed increases, the vehicle's braking performance decreases, the friction coefficient drops, and the braking distance extends, making it difficult to stop the vehicle promptly when needed. Additionally, higher speeds increase vehicle vibration and jolting, affecting safe driving. 2. Increased vehicle wear: High-speed operation intensifies the vehicle's working load and stress, accelerating the wear and damage of mechanical components. This is particularly detrimental to the wheels, causing not only jumping and dragging wear but also raising the friction temperature, which can lead to rapid tire aging and deformation, increasing the risk of tire blowouts.
