- Reduced visibility at night causes approximately 50% of all road accidents
- Nearly 1 in 5 crashes happens on dark roads without street lighting
- Drivers have a 3.4 times higher chance of crashing when they are fatigue or drowsy at night

- Older drivers are more at risk at night due to declining vision, accounting for 70% of nighttime crash fatalities among seniors
- Traffic volume drops by about 60% at night, but the fatal crash rate per mile is 3 times higher
- Approximately 33% of distracted driving crashes occur at night
- The average duration of night shift work is around 8 hours, with increased risk of fatigue-related crashes

Did you know that despite only 25% of driving occurring at night, over 50% of traffic fatalities happen then, making nighttime driving three times more dangerous than daytime?
Driver Behavior and Decision-Making
- Drivers have a 3.4 times higher chance of crashing when they are fatigue or drowsy at night
- Headlights improve visibility range by up to 150 meters, but many drivers underutilize them at night
- Driving under the influence of alcohol at night increases crash risk by 7 times
- Use of high-beam headlights can reduce the chance of a crash by 30% on rural roads, but only about 20% of drivers use them appropriately
- 60% of drivers admit to occasionally driving at night when feeling drowsy, despite knowing the risks
- Most car headlights have a range of about 100-150 meters, but many drivers neglect to switch to high beams to maximize visibility
- More than 45% of nighttime crashes involve tailgating or aggressive driving behaviors, often exacerbated by poor visibility

- Nearly 20% of all nighttime crashes involve other vehicle occupants, mostly juveniles and young adults
- The secondary crash risk is highest within the first 15 seconds after the initial accident, especially at night
- Motorcycles are involved in about 25% of all fatal crashes at night, though they account for only 3% of all registered vehicles
- Nighttime pedestrian fatalities make up roughly 70% of all pedestrian deaths, indicating higher vulnerability after dark
- Sleep deprivation contributes to approximately 15% of all accidents during night driving
- About 40% of fatal crashes happen on rural roads at night, with fewer streetlights and higher speeds

- Use of alcohol reduces night vision ability by up to 50%, significantly impairing driving capability
- Drivers aged 65 and older are involved in 15% of traffic fatalities at night, pointing to age-related vision and driving issues
- The average car travels around 200 miles during night trips, but the crash rate per mile is disproportionately high
- Nearly 60% of drivers admit to having difficulty judging the distance of other vehicles at night, increasing crash risk
