Intersection and Nighttime Factors

Crashes at intersections frequently involve issues of right-of-way, visibility, and timing. Left-turn collisions are a well-documented hazard for motorcyclists, often stemming from drivers misjudging a motorcycle’s speed or failing to detect the smaller visual profile of a bike. The early morning hour introduces added variables such as:

- Reduced visibility and glare from artificial lighting
- Potential fatigue among motorists
- Roadway conditions, including dew, oil buildup, or limited sightlines
- Signal phase and timing, including protected versus permissive left-turn cycles
