What should a driver do if there are hazardous conditions, such as ice, snow, or fog?

Answer: B — educe speed and increase distance from other vehicles

Drivers should always reduce speed and increase distance from other vehicles when facing hazardous conditions such as ice, snow, or fog. This is because these conditions decrease visibility and reduce traction, making it more dangerous to drive at normal speeds and follow other vehicles closely. It is important to adjust driving behavior to match the current weather and road conditions, rather than trying to reach a destination faster. Decreasing the use of headlights and ignoring the conditions altogether can also increase the risk of accidents and should be avoided.
