Regulations & HealthQuestion 118 of 120
You are two hours from your delivery when you realize you are struggling to stay awake and have drifted within your lane. What does the regulation require?
a.Continue if you can open a window and drink coffee
b.Continue but reduce speed by 10 mph
c.Continue because you still have driving hours available
d.Stop driving, because a driver whose alertness is impaired by fatigue or illness may not operate a commercial vehicle
Explanation
The rule prohibits operating while ability or alertness is impaired by fatigue, illness, or any other cause, regardless of hours remaining. Caffeine, fresh air, and lower speed do not restore alertness, and available hours never authorize driving while impaired.
