Under which conditions is it considered dangerous to drive?

Driving during conditions such as rain, fog, snow, or ice is considered dangerous because these weather elements significantly reduce visibility and traction on the road. Rain can create slippery surfaces, while fog drastically cuts down on how far ahead a driver can see. Snow and ice can make roads very treacherous, leading to longer stopping distances and increased chances of losing control of the vehicle. These conditions require heightened awareness, slower speeds, and often, the use of specialized tires or equipment to help maintain control while driving.

In contrast, sunny weather generally provides good visibility and road conditions, morning hours are typically safe with clear driving conditions, and using headlights is a standard practice to enhance visibility, especially during low-light conditions, rather than being dangerous. Thus, the correct response highlights the specific adverse weather conditions that pose significant risks to drivers and other road users.
