Driving while drowsy is one of the greatest dangers behind the wheel. It has been estimated that this risk factor accounts, directly or indirectly, for between 15 and 30% of traffic accidents. Moreover, crashes caused by drowsiness tend to be particularly serious. The most important rules to avoid having an accident due to drowsiness or fatigue are: - If we feel tired or drowsy while driving, the most advisable thing is to stop and rest in a suitable place and sleep for about 20 to 30 minutes. - Rest for 20 to 30 minutes every 2 hours or every 200 kilometres at most. - Always be alert to the signs and symptoms of drowsiness or fatigue.
