Which of the following should a driver do in adverse weather conditions?

In adverse weather conditions, it is crucial for a driver to increase their following distance. This practice allows for more reaction time in case the vehicle in front suddenly stops or skids, which is more likely to occur in poor weather conditions like rain, snow, or fog. By increasing the space between vehicles, drivers can better manage their stopping distance and have a clearer view of the road ahead, thereby enhancing overall safety.

Maintaining a normal speed or speeding up might contribute to a loss of control due to slippery conditions, while using high beams can impair visibility in fog or heavy rain, since the light may reflect off the precipitation and create glare. Increasing following distance stands out as the safest and most effective action a driver can take to mitigate risks associated with adverse weather.
