What environmental factor is particularly crucial for drivers to consider during dusk and dawn?

During dusk and dawn, wildlife activity peaks are particularly crucial for drivers to consider due to the heightened likelihood of animals being active and crossing roads during these times. Animals such as deer, for example, are more likely to be on the move in search of food and can often be unexpected hazards on the road.

At these times, visibility is often reduced, making it more challenging for drivers to spot wildlife before it's too late. Additionally, the behavior of many species makes them more active during twilight hours, increasing the risk of collisions. By being aware of this peak activity, drivers can adopt more cautious driving habits, such as reducing speed and remaining vigilant, especially in areas known for wildlife crossings.

Other environmental factors like traffic patterns, weather conditions, and road surface quality are typically important to consider but may not have the same level of direct impact on driver safety specifically during dusk and dawn as the potential for wildlife encounters does.
