Which of the following about speed management is correct?

Speed management is a crucial aspect of safe driving, particularly for commercial drivers. The correct choice emphasizes that when driving on wet roads, it is advisable to reduce speed significantly, typically by about one-third. This reduction is important because wet surfaces can reduce tire traction, increasing the risk of skidding and loss of control. By slowing down, drivers give themselves more time to react to potential hazards and maintain better control of the vehicle.

Maintaining the same speed in all conditions can lead to dangerous situations, as different weather and roadway conditions present unique challenges that require adjustments in driving behavior. Increasing speed on slippery roads can drastically increase the risk of accidents, as it can exacerbate the effects of reduced tire traction. Similarly, assuming that speed reduction is not necessary for packed snow overlooks the need for cautious driving in such conditions, as snowy surfaces can significantly affect vehicle handling and stopping distances. Thus, the emphasis on reducing speed on wet roads is crucial for enhancing safety and maintaining control in varying driving conditions.
