Why must you lower your speed in poor driving conditions?

Lowering your speed in poor driving conditions is essential to ensure safety, regardless of the posted speed limit. Poor conditions, such as rain, snow, fog, or ice, can reduce visibility and traction, making it more difficult to control the vehicle or react to hazards. By decreasing your speed, you increase your ability to respond effectively to unforeseen challenges on the road, such as other vehicles, pedestrians, or obstacles.

The posted speed limits are generally set for optimal conditions and do not account for adverse weather or road surfaces. Therefore, driving slower than the posted limit during these times is a critical safety practice to help prevent accidents and maintain control of the vehicle. This proactive approach prioritizes safety over merely following regulations or trying to maintain efficiency, emphasizing the importance of adapting driving behavior to actual roadway conditions.
