For people learning to drive, there are many skills that must be acquired. In addition to navigating different hazards and managing distractions, new drivers must also learn to drive safely in conditions where visibility is poor, such as night. But the crash rate is still too high.
A study sponsored by the Department of Infrastructure and Regional Development found that young or inexperienced drivers were more likely to be slower at anticipating hazards at night. In addition, novice drivers were also found to be more at risk of experiencing acute sleepiness when they were behind the wheel both at night or in the early hours of the morning.
As such, a number of states have regulations in place to limit the amount of unsupervised nighttime driving for learners.
