How can you tell that you are getting tired while you are driving?

You answered correctly. Signs of fatigue while driving include heavy eyelids and frequent yawning. These are common physical symptoms that your body gives when you are tired and your concentration starts to fail. Recognizing these signs is important because driving while tired significantly increases the risk of accidents. Quicker reaction time is not a sign of tiredness; in fact, being tired usually slows your reactions. Always take a break or switch drivers if you notice symptoms like heavy eyelids or yawning to stay safe on the road.
