Tiredness in traffic – risks & reducing tiredness

Tiredness is an indication that your body needs to recuperate in order for all your senses to function optimally.

It is forbidden and punishable to drive if you are incapable of driving the vehicle in a safe manner. Your reaction time after a sleepless night is comparable to that of a drunk person.

• Sleep deprivation.
• Alcohol, drugs and certain medications.
• Monotony:
  • Wide, long and straight uninterrupted roads.
  • Engine noise.
  • Noise from the tyres.

Tiredness glossary

• Microsleeping: When you nod off and wake up almost immediately with a jerk of the head. Microsleeping lasts for a very short period of time, often less than a second.
• Sleep apnoea: Breathing problems that disrupt your sleep at night. The lack of sleep resulting from this issue leads to a significantly higher risk of tiredness-related traffic accidents.
• Nap: Light and short sleep (15–30 minutes).
