At twilight, our eyes experience a rapid adaptation from bright daylight to dim light, a process known as the photopic to mesopic transition. This temporary reduction in visual acuity can make it harder to detect lane markings, signage, or other vehicles.
To top it off, sun glare during late-afternoon commutes can make it even harder to see the road, increasing the likelihood of misjudging distances or failing to recognize “Do Not Enter” or “Wrong Way” signs.
Modern traffic patterns and ongoing construction projects throughout Hampton Roads have created an intricate network of interchanges that can challenge even experienced drivers. In high-traffic areas, particularly along I-64, I-264, and I-464, drivers often face a quick succession of exits, merges, and lane shifts.
When visibility is limited by dusk or darkness, it becomes easier to misread signage or accidentally enter the wrong ramp.
Virginia’s older interchanges, particularly in Norfolk and Chesapeake, often feature closely spaced entrance and exit ramps, which can contribute to driver confusion and error, especially after dark when visual cues are reduced.
Limited signage, complex ramp geometry, and the need for rapid lane changes further increase the risk of accidents in these areas.
Early sunsets align with the body’s natural circadian dip in alertness, typically occurring between 2:00–4:00 AM and 2:00–4:00 PM. This physiological low can impair reaction time, decision-making, and situational awareness.
Couple these factors with rush hour traffic, public transport, and school buses, and you’re looking at a particularly hazardous evening commute.
Additionally, drivers may experience cumulative fatigue from the workday or engage in social activities involving alcohol, both of which further increase the risk of disorientation and wrong-way driving.
