What is the main reason to slow down when driving on slippery roads?

Slowing down on slippery roads is essential primarily to reduce the stopping distance. When road surfaces are slick due to rain, ice, or snow, traction between the tires and the road is significantly compromised. This reduction in friction means that a vehicle requires a longer distance to come to a complete stop compared to driving on dry pavement. By decreasing speed, drivers can better control their vehicles, react to unexpected obstacles, and ensure they have adequate distance to stop safely without skidding.

Though enjoying the scenery, allowing for faster merging, and preventing overheating the brakes might come to mind in different contexts, they do not directly address the key safety concern of maintaining control and stopping efficiently on slippery surfaces. Prioritizing reduced speed is a crucial strategy for ensuring safety under these hazardous driving conditions.
