**Drowsiness** is a state of tiredness and sleepiness that can severely affect the ability to drive. It is not necessary to fall completely asleep for an accident to occur; the symptoms of drowsiness can appear before falling completely asleep.
- **Causes of drowsiness**: Sleeping fewer hours than usual or sleeping poorly, even if many hours are slept, are common causes of drowsiness. Changing sleep hours can also lead to this state.
- **Symptoms of drowsiness**: Include difficulty keeping the head upright, blurred vision, frequent yawning, loss of concentration, and being easily distracted. These symptoms indicate that it is dangerous to continue driving.
Therefore, if you have slept little or poorly, it is more likely to experience drowsiness at the wheel, which increases the risk of accidents.
