All of the following are effective countermeasures of fatigue ue except a) Preparing for regular breaks when driving long distances b) Keeping good posture Allowing fresh air into the car d) Allowing your eyes to lose focus

The correct answer is d) Allowing your eyes to lose focus.<br /><br />Fatigue while driving can be dangerous and lead to accidents. To counteract fatigue, it is important to take certain precautions. Preparing for regular breaks when driving long distances (option a) is an effective countermeasure as it allows the driver to rest and rejuvenate. Keeping good posture (option b) can also help reduce fatigue as it promotes proper blood flow and reduces strain on the body. Allowing fresh air into the car (option c) can also help alleviate fatigue as it provides a refreshing environment for the driver.<br /><br />However, allowing your eyes to lose focus (option d) is not an effective countermeasure of fatigue. It is important to keep your eyes focused on the road and maintain concentration while driving to ensure safety.
