What must drivers be especially careful of during twilight hours?

During twilight hours, visibility is significantly reduced, making it more challenging for drivers to see their surroundings. One major concern during this time is the presence of vehicles coming from the opposite direction that may not have their lights on. This is particularly critical because many drivers may forget or neglect to turn on their headlights, especially as it transitions from daylight to darkness. Without the illumination from headlights, these vehicles become difficult to perceive, increasing the risk of collisions.

This time of day often catches drivers off guard due to changing light conditions, which can lead to misjudgments about the presence and speed of oncoming traffic. Being vigilant about vehicles without lights is essential for safety. Drivers must maintain awareness and be prepared to respond appropriately if they notice such vehicles to avoid accidents.

While factors like increased pedestrian activity and cross traffic are typically heightened during twilight, the particular risk posed by vehicles without lights directly influences the immediate need for cautious driving in terms of visibility and reaction time.
