Making abrupt lane changes in inclement weather is not recommended because it can destabilize the vehicle and create dangerous situations. Poor traction during rain, snow, or ice can make it hard to control the vehicle when sudden movements are made. Abrupt changes can lead to loss of control, skidding, or collisions, especially if the road surface is slick. In adverse conditions, maintaining smooth and gradual movements is crucial for safety. In contrast, slowing down helps to adapt to reduced visibility and traction. Maintaining a safe following distance allows for adequate reaction time in case the vehicle in front suddenly stops or skids. Using headlights in heavy rain is essential for visibility, ensuring that both the driver and other road users can see each other clearly. These practices enhance safety, while making abrupt lane changes increases risk.
