What is the responsibility of the driver when driving in bad weather?

When driving in bad weather, the primary responsibility of the driver is to adjust their speed and increase their following distance to maintain safety. Bad weather conditions, such as rain, snow, or fog, can significantly reduce visibility and traction on the road. By decreasing speed, drivers can have more time to react to unforeseen obstacles or changes in traffic, while extending the distance between their vehicle and the one in front allows for a longer reaction time in case of sudden stops or hazards.

The other options presented relate to unsafe practices during adverse weather conditions. Using high beam headlights can actually hinder visibility in fog or heavy rain, as it can cause glare. Maintaining normal speed and following distance without considering the weather conditions can lead to dangerous situations, as it may not allow for adequate responses. Driving on the shoulder is often not safe or legal, and it does not guarantee better traction, especially if the shoulder is also slippery. Thus, adjusting speed and increasing following distance is crucial for ensuring the safety of the driver and other road users in inclement weather.
