What should you never do when driving in heavy rain?

Using high beams while driving in heavy rain should be avoided because the intense light can reflect off the rain droplets, creating glare that impairs your visibility. This glare can make it much harder to see the road, other vehicles, and any potential hazards. In heavy rain, visibility is already reduced, so utilizing low beams is more effective. Low beams provide better illumination of the road immediately in front of you without creating excessive glare. Additionally, the use of high beams can be disruptive to other drivers on the road, further complicating driving conditions for everyone involved.

The other options are safer practices for driving in heavy rain. For instance, using normal headlights helps improve visibility without adding glare, slowing down and increasing following distance allows for greater reaction time, and keeping windows closed ensures that water doesn’t enter the vehicle.
