Which of the following is a recommended action when driving in heavy rain?

When driving in heavy rain, reducing speed and increasing following distance is crucial for safety. Rain can significantly decrease visibility and traction on the roadway, which makes it more challenging to control your vehicle. By reducing your speed, you give yourself more time to react to sudden hazards or changing road conditions, allowing for safer maneuvering.

Increasing the following distance is equally important, as wet roads can lead to longer stopping distances. This extra space helps prevent accidents by ensuring that you have ample room to stop if the vehicle in front of you brakes suddenly or if you encounter aquaplaning.

Driving at the speed limit in adverse weather doesn’t account for the change in driving conditions, and using high beam headlights can create glare in wet conditions, reducing visibility rather than enhancing it. Positioning the vehicle only in the middle of the lane does not address the varying conditions and doesn't provide enough flexibility to navigate safely around obstacles or other vehicles.
