What should you be cautious of during the first half-hour of rain?

During the first half-hour of rain, the primary concern for drivers is that the roads can become particularly slippery due to a mix of water and oil. In dry conditions, roads accumulate oil and other substances. When it starts to rain, the initial water will mix with these materials, creating a slick surface that significantly reduces traction. This can lead to an increased risk of skidding or losing control of the vehicle.

It's essential for drivers to be especially cautious during this period, as their vehicle may not respond as predictably as it would on a completely dry road. Adjusting driving behavior, such as reducing speed and increasing following distances, is crucial to maintaining safety under these conditions. Keeping an eye out for changes in road handling can help prevent accidents during this vulnerable time.
