Pull over for coffee and a short nap when you feel drowsy driving
Added
If you drive for rideshare or long shifts, plan for 7 to 9 hours of sleep and watch for warning signs like drifting from your lane or forgetting the last few miles. When they show up, CDC says to pull over somewhere safe, have a cup of coffee and take a 15-30 minute nap; the effect is temporary, and only sleep fixes fatigue.
The result
Result: CDC NIOSH: after 17 hours awake, impairment is equivalent to a blood alcohol content of .05, and after 24 hours it is equivalent to .10.
