Which of the following is an important action to take when driving in bad weather?

Reducing speed is essential when driving in bad weather due to several reasons. Adverse weather conditions, such as rain, snow, ice, or fog, significantly decrease visibility and the traction between your vehicle and the road. By lowering your speed, you give yourself more time to react to unforeseen circumstances, such as sudden stops of other vehicles or obstacles on the road. Additionally, a reduced speed can help maintain better control of the vehicle, which is crucial when the road conditions are slick or slippery.

In contrast, using high beams can create glare and reduce visibility in conditions like fog or heavy rain. Following closely behind another vehicle can lead to dangerous situations, especially if the lead vehicle stops suddenly, leaving little room to react. Ignoring weather conditions altogether disregards the significant impact they can have on driving safety and vehicle handling, leading to potentially hazardous situations for both the driver and others on the road.
