What is the only effective and safe solution when a driver experiences early symptoms of fatigue (heavy eyelids, yawning, drifting between lanes) while driving?

1. Turn the radio to maximum volume and open the windows
2. Stop in a safe, designated parking area, stretch, and take a 20-30 minute sleep nap or switch drivers
3. Drive faster to reach the final destination earlier
4. Drink multiple cans of sugary soda while continuing to drive
