Driver fatigue remains one of the most influential factors of vehicle crashes to this day

After prolonged periods of continuous driving, drivers experience mental and physical functional disorder. Lack of a proper sleep prior to driving can lead to fatigue in even short periods of driving. Fatigue affects a drivers attention, feeling, perception, judgement, decision making and reaction times.

Fatigue Warning Signs

Warning signs of fatigue are able to be easily detected by a driver through early signs and physical warning signs. Teaching drivers which behaviours or patterns may indicate that they are experiencing fatigue will allow them to identify when fatigue may be affecting their judgement.The symptoms of fatigue can be categorised into two sections; early warning signs, and physical warning signs.

The Ixonn DS Technology facial recognition system is able to detect physical symptoms of driver fatigue through analysis of facial features and use this information to alert the driver and headquarters. Ixonn DS Technology also monitors early warning signs that present in the form of the vehicles movements, such as inconsistent and sporadic speeding and slowing of the vehicle and hard breaking. By monitoring the drivers physical signs and reaction times, Ixonn DS Technology is able to effectively identify driver fatigue and counteract its effects.

Early warning signs include:

  • Wandering Thoughts
  • Missing a Gear
  • Breaking Late
  • Unintentionally Slowing or Speeding

Physical warning signs include

  • Yawning
  • Increased blinking frequency
  • Memory loss
  • Heavy Head


Driving tired can cause a person to drift in and out of sleep without realising. This is called a micro-sleep and usually lasts 3-5 seconds. Micro-sleep has been found to be the main cause of fatigue-related crashes.

A micro-sleep for 5 seconds at 110/km/h means the vehicle has traveled 152m without a driver in control

20% of fatal road accidents involve driver fatigue

A Driver who has been awake for 17 hours faces the same risk of crash as someone with a BAC of 0.05g/100ml

If a driver falls asleep for 4 seconds at a speed of 100km/h the car will have gone 111meters without a driver in control

Motorists who drive tired remain the second biggest killer on NSW roads

Crashes due to fatigue are twice as likely to be fatal

The risk of fatigue incidents for a truck driving between midnight and 6am triples

85% of heavy vehicle crashes involving fatigue occur within the first four hours of the journey

Shifts over 12 hours increase drowsiness events by 2x
