雨雪天气路面湿滑 安全行车技巧要了解

Core Viewpoint - The article emphasizes the importance of safe driving practices during winter weather conditions, particularly in rain and snow, highlighting the risks associated with low road traction and the need for caution while driving [1][2][4]. Group 1: Driving Conditions and Risks - Icy and snowy road surfaces have low traction coefficients, leading to longer braking distances and increased risks of accidents such as rear-end collisions and skidding [2][4]. - The traction coefficient for dry asphalt is approximately 0.8, while it drops to around 0.2 for compacted snow and 0.1 for icy surfaces, indicating that braking distances can be over four times longer on icy roads compared to dry roads [4]. Group 2: Safety Driving Tips - Drivers should utilize features like TCS (Traction Control System) and ESP (Electronic Stability Program) to enhance vehicle stability on icy roads [6]. - It is crucial not to rely solely on ABS (Anti-lock Braking System) for emergency braking, as it does not shorten braking distances [8]. Group 3: Misconceptions about Intelligent Driving - There are common misconceptions regarding the use of "smart driving" features in winter conditions, as drivers may not fully understand the limitations of automated driving technologies [10][11]. - Maintaining the cleanliness of vehicle sensors is essential for the effective operation of intelligent driving systems, especially in snowy or icy conditions [13]. Group 4: Specific Weather Conditions - The phenomenon known as "ice crust" can form after snowfall, creating extremely slippery conditions that significantly increase the risk of vehicle loss of control [14][15]. - Drivers should be vigilant for signs of "ice crust" on the road, such as a deepening color or reflective sheen, and adjust their driving accordingly [17][19]. Group 5: Recommendations for Freezing Rain - In freezing rain conditions, it is advisable to minimize driving and to be aware of road conditions, particularly on bridges and elevated structures where ice is more likely to form [22][24]. - Drivers should prepare for potential hazards by reducing speed and avoiding sudden maneuvers, especially in areas prone to ice accumulation [24][26].
