Feeling drowsy while driving a commercial vehicle is a serious issue that can lead to unsafe conditions for both the driver and others on the road. Taking a break and resting is the most responsible and effective action to take in this situation.

Rest breaks allow the driver to recover from fatigue, which is critical for maintaining focus, reaction time, and overall safe driving practices. Fatigue can impair judgment and slow down response times, making it more difficult to respond to unexpected situations on the road. By resting, you give your mind and body a chance to recharge, reducing the risk of an accident caused by drowsiness.

While changing the radio station, drinking coffee, or opening a window might provide temporary distractions or boosts in alertness, these actions do not address the root cause of drowsiness. They may not effectively combat fatigue and can lead to dangerous situations if not addressed properly. Prioritizing rest ensures that drivers remain alert, attentive, and safe while operating heavy vehicles.
