Always pull completely off the roadway, onto the shoulder or a safe area, and turn on hazard flashers to warn other drivers.
Question 3: What is the main danger of driving when fatigued?
- Slowed reaction time and risk of falling asleep at the wheel (Correct answer)
- Reduced fuel efficiency

Correct answer: Slowed reaction time and risk of falling asleep at the wheel
Fatigue slows reaction time and can cause microsleeps at the wheel, making it as dangerous as drunk driving.
Question 4: When driving on a two-lane road and a vehicle ahead of you is turning left, you should:
- Slow down and prepare to pass on the right when safe (Correct answer)
- Sound your horn and pass on the left immediately
- Tailgate to encourage the driver to speed up
- Stop completely and wait until the turn is complete
Correct answer: Slow down and prepare to pass on the right when safe
Slow down and, when the shoulder or additional lane allows, carefully pass on the right only after ensuring it is safe to do so.
Question 5: What should you do when driving through a large puddle of water?
- Slow down, drive through slowly, then test brakes gently (Correct answer)
- Accelerate to pass through quickly
- Drive through at normal speed to minimize exposure
- Stop before the puddle and wait for it to drain
Correct answer: Slow down, drive through slowly, then test brakes gently
Drive through standing water slowly to avoid hydroplaning, then lightly tap your brakes to dry them out afterward.
Question 6: What is the purpose of rumble strips on Tennessee highways?
- To alert drowsy or distracted drivers that they are leaving the travel lane (Correct answer)
- To reduce vehicle speed in construction zones
- To provide better traction in wet conditions
- To mark the boundary between the road and the median
Correct answer: To alert drowsy or distracted drivers that they are leaving the travel lane
Rumble strips create a loud vibration when driven over, alerting drivers who are drifting out of their lane due to distraction or fatigue.
