  1. A
    Drinking high-caffeine energy drinks or strong coffee

    Rolling down the driver's side window to let in cold, fresh air

  4. D
    Increasing the volume of the cab radio and chewing gum

Answer

Pulling over in a safe, designated parking area to sleep is the only effective solution to overcome driver fatigue.
Adequate sleep is the only real and permanent cure for fatigue. When a driver shows signs of drowsiness, the only safe and compliant action is to find a secure parking location and rest.

Step-by-Step Solution

1
Identify the driver's symptoms
The driver exhibits clear physiological signs of acute drowsiness and impaired motor control.
Recognizing early warning signs of fatigue is essential to avoiding critical driving errors and crashes.
2
Evaluate potential countermeasures against official safety principles
Temporary alertness 'tricks' do not address the brain's biological need for sleep.
CDL regulations and medical science establish that sleep is the sole remedy for sleep debt.
3
Select the correct corrective action
The vehicle must be safely parked so the driver can obtain restorative sleep.
This removes the immediate crash hazard and restores safe driving performance.
