When are collisions involving drowsiness most likely to occur?

Collisions involving drowsiness are notably more likely to occur during the early morning and late afternoon. In the early morning, typically between 12 a.m. and 6 a.m., many drivers may be experiencing significant fatigue, particularly if they were awake late or did not get adequate sleep. This time frame aligns with natural circadian rhythms, where most individuals feel a dip in alertness.

In addition, late afternoon can also be prone to drowsiness as it approaches the end of a typical workday. Drivers who may have not taken breaks or have been on the road for extended periods can experience a decrease in focus and increased fatigue. This combination of factors contributes to a higher likelihood of collisions during these specific times compared to the other options listed.
