Driving when tired

The No.1 cause of fatal accidents

on European roads, claiming more lives than speeding or alcohol.

fatal or serious accidents are caused by driver fatigue

Contrary to popular belief, it is impossible to fight sleep when driving. Stop. Revive. Survive.

StopSleep to fight low vigilance and driver fatigue

StopSleep The objective :
Reducing the number of accidents caused by driver fatigue and reduced concentration

A recent scientific study in France found that more than 800 deaths a year could be prevented with StopSleep.

However StopSleep is not a product designed to keep you awake when you are too tired to drive. If you are aware that you are too tired, you pull over and take a break. You have a cup of coffee and maybe a short nap. The problem is not necessarily about falling asleep at the wheel, the problem is that the more tired you get the harder it is to remain alert and vigilant at the wheel and to concentrate fully on driving your vehicle safely.

Unfortunately the effects of driver fatigue and accidents caused by a loss of concentration contribute to a huge percentage of accidents on Europe's roads. Most reports put the figure above 20%, higher than the number of accidents caused by alcohol or excessive speed. Whilst we know we should stop when we are too tired, we are potentially at most risk during the period leading up to taking that break, when driver fatigue has set-in and our concentration is starting to drop. These drops in concentration can be very subtle, so subtle they are imperceptible to a human being. And a drop in concentration and awareness, in modern vehicles, that are quieter and more comfortable than ever, cocooning us from our surroundings, makes it easier for us to move quickly from just a loss of awareness and concentration to 'micro-sleep' and an even greater chance of having an accident.

A recent scientific study conducted in France, showed that on a journey from Paris to Lyon, the test driver had unconsciously accumulated 6 minutes of sleep, with each period of 'micro-sleep' ranging from 1 second to a massive 6 seconds, without him having any idea it had happened. The driver felt sure he had successfully kept himself awake for the entire journey. So, although you might think you are always in complete control, it is entirely possible that even though you are doing your best to remain awake and alert, you are subconsciously, regularly, losing your concentration and awareness and slipping in to the highly dangerous state of 'micro-sleep'. Whilst you may claim you have not physically fallen asleep at the wheel, can you really claim you have remained 100% alert and in the 'present' for the entire journey ?

That is why we have designed StopSleep. Yes, StopSleep will alert you when it recognises that you are too tired to drive safely, but more importantly StopSleep will alert you as soon as it notices that you are starting to lose your concentration. StopSleep will alert at the first signs of a drop in awareness, activating even before you reach the dangerous state of 'micro-sleep' ensuring you always remain alert and safe at the wheel.

User recommendations

StopSleep has been designed to alert in case of drowsiness and drops in concentration and awareness. StopSleep should not be used as substitute for driving with due care and attention. The user is responsible for paying full attention to road conditions and under no circumstances should StopSleep be used to attempt to keep the user awake when feeling over-tired or too tired to drive safely. When driving always take regular breaksand always take a break at the first signs of fatigue or a drop in concentration. If StopSleep alerts, stop driving immediately.

Scientific recommendations.

Further to our study, as soon as StopSleep alerts, we recommend that driver's should immediately assess their current level of fatigue and concentration. If they recognise that they are starting to feel drowsy and their awareness has decreased they should take the most appropriate action immediately: stop driving
