Final answer:
In poor weather conditions such as rain, snow, or fog, use low beam headlights instead of high beams to prevent glare and enhance visibility. Exercise caution as weather conditions can affect road surface traction and vehicle control.
Step-by-step explanation:
When driving through poor weather conditions such as rain, snow, or fog, you should not use your high beam headlights. The high beams can reflect off the precipitation and cause a glare, reducing visibility even further. Instead, it is advised to use low beam headlights or fog lights if your vehicle is equipped with them. This helps to illuminate the road directly in front of your vehicle without causing reflection that can impair your vision or the vision of oncoming drivers.
Additionally, in certain weather situations like light rain, oil and gasoline on the road surface can make the road slippery, leading to reduced vehicle control. Heavy rain might wash away some contaminants, but it also increases the risk of hydroplaning where your vehicle could skid uncontrollably on water buildup. Therefore, maintaining appropriate speed and using the correct lighting can greatly improve safety.
