What should you do if driving conditions suddenly change, such as rain?

When driving conditions suddenly change, such as during rain, it is crucial to slow down and increase your following distance. Rain can lead to slippery roads, which reduces traction and increases stopping distances. By slowing down, you provide yourself with a greater margin for error, allowing more time to react to unforeseen circumstances, such as sudden stops by other vehicles or obstacles on the road.

Additionally, increasing your following distance is essential in wet conditions because it allows for a longer reaction time and helps prevent rear-end collisions. If the vehicle in front of you brakes suddenly, a greater distance gives you more time to respond appropriately without the risk of skidding or losing control of your vehicle.

In contrast, the other approaches can be dangerous. Ignoring the changing conditions would leave you vulnerable to losing control. Turning on high beams in rain is not advisable, as it can cause glare and reflection, impairing visibility. Maintaining the same speed does not account for decreased traction or the need for longer stopping distances, making it a risky decision while driving in adverse weather.
