If driving in adverse weather conditions, what should you do?

Answer: B — Reduce speed and increase following distance

Reducing speed and increasing following distance is crucial when driving in adverse weather conditions such as rain, snow, fog, or ice. Adverse weather can significantly affect vehicle handling and stopping distances. By slowing down, drivers have more time to react to unexpected situations, such as a sudden stop from the vehicle ahead or changes in road traction. Increasing the following distance allows more room to stop safely if necessary; this is particularly important because braking distances can be longer on slippery surfaces. This strategy enhances both the driver's safety and the safety of other road users. The other options do not prioritize safety effectively under adverse conditions, as they advocate for behaviors that could lead to increased risk of accidents.
