A study comparing sleep deprivation and alcohol on driving performance found that 24 hours of wakefulness impairs drivers more than being slightly above the legal alcohol limit. Sleep deprivation leads to slower reaction times, reduced lane control, and microsleeps. Coffee, often used as a fatigue countermeasure, failed to improve driving performance, and drivers tend to underestimate their level of impairment. This highlights the significant dangers of driving while sleep deprived, especially for shift workers.
