On what type of roads do drowsy driving crashes typically occur?

Drowsy driving crashes typically occur on rural roads and highways primarily due to the characteristics of these types of roads. Rural roads often have less traffic, allowing for higher speeds, which can lead to more severe crashes when a drowsy driver loses control. These roads may also lack the frequent stopping points or distractions typically found in urban areas, which can allow a driver to stay behind the wheel longer than they should without taking necessary breaks. Highways pose a similar risk due to their long stretches of uninterrupted driving, where fatigue can build up over time without the driver realizing it. The combination of speed and length of travel on these roads significantly increases the potential for serious accidents involving drowsy drivers.
