Which of the following is a sign of drowsy driving?

Frequent yawning is a strong indicator of drowsiness and is recognized as a physiological response that signals the body’s need for rest. Yawning occurs when the brain is not receiving enough oxygen or when someone is feeling fatigued, making it a clear and common symptom of drowsy driving. Being tired can severely impair judgment, reaction times, and overall driving ability, making it critical to recognize signs like yawning that suggest a driver should take a break or find an alternate way to rest before continuing to drive.

Listening to loud music or driving with the windows open may be strategies some people employ to stay awake, but they do not inherently indicate drowsiness. Having a passenger awake could promote alertness, but it alone does not signify that the driver is experiencing drowsiness. Thus, frequent yawning stands out as a direct and unmistakable sign that a driver may be falling asleep at the wheel.
