What time frame is advised to avoid driving due to drowsy driving risks?

The recommended time frame to avoid driving due to drowsy driving risks is from 10 p.m. to 6 a.m. This period is particularly crucial as it aligns with the body's natural circadian rhythms, which promote sleepiness during the night hours. Many individuals experience significant fatigue and a tendency to fall asleep during these times, which can greatly impair driving abilities.

Driving during late-night hours often coincides with decreased alertness and slower reaction times, making it more likely for drivers to encounter dangerous situations on the road. Thus, it is essential for drivers to recognize these high-risk hours and prioritize rest to ensure their safety and that of other road users.

The other choices suggest times where drowsiness may not be as pronounced or are less universally recognized for their risks related to drowsy driving. However, the window from 10 p.m. to 6 a.m. is consistently highlighted in safety materials as a particularly hazardous period for fatigue-related incidents.
