What environmental factor can contribute to driver inattention?

Heavy rain is a significant environmental factor that can contribute to driver inattention for several reasons. When it rains heavily, visibility can become severely reduced due to water splashing, fogging of windows, and the difficulty of seeing road signs and other vehicles clearly. This decreased visibility demands more focus from the driver and can lead to increased distraction or hesitation. The wet road surface can also create a risk of hydroplaning, which may distract the driver and lead to further inattention as they react to the driving conditions. Additionally, the sound of heavy rain can drown out important auditory cues like horns or sirens, making it harder for drivers to stay aware of their surroundings.

Clear weather typically allows for better visibility and less distraction from environmental conditions, while bright sunlight can lead to glare issues but does not necessarily draw attention away from driving as much as heavy rain. Low light conditions, such as driving at night, can also pose challenges, but they primarily affect visibility rather than inducing distraction in the same way that heavy rain can.
