What should a driver do if they feel tired while driving?

When a driver feels tired while driving, taking a break or switching drivers if possible is the best course of action. Fatigue can significantly impair a driver's reaction time, concentration, and decision-making abilities, similar to the effects of alcohol. It is crucial for safety to manage fatigue proactively.

Taking a break allows the driver to rest and regain alertness, reducing the risks associated with drowsy driving. If another licensed driver is available to take over, switching drivers is highly effective as it directly addresses the problem of fatigue by allowing the original driver time to rest and recuperate.

While other options, such as drinking caffeine or opening the windows for fresh air, might provide a temporary boost or increase alertness, these methods are not substitutes for rest. They may delay the inevitable onset of fatigue but do not eliminate the underlying issue of tiredness. Continuing to drive while tired is dangerous and increases the likelihood of accidents.
