Drivers must be especially careful when passing during which condition?

Drivers must be particularly cautious during twilight hours due to the unique lighting conditions that can create challenges for visibility. During this time, the transition between day and night can result in vehicles and pedestrians being less visible, which can hinder the driver's ability to judge distances and the speed of oncoming traffic effectively. This reduced visibility can lead to miscalculations in space and timing when attempting to pass another vehicle.

In comparison, while rainy weather, foggy conditions, and snowy roads also present significant hazards that require careful driving, twilight hours encompass a range of both visual and perceptual challenges that can be particularly deceptive. Additionally, the approaching darkness can create contrasts in lighting that affect how objects are perceived. Proper caution is essential during twilight to avoid accidents and ensure safe driving when passing other vehicles.
