I had ver heard of microsleep until I watched an accident investiagtion documentary on TV last week. It claims that many accidents on the road are created from microsleeps which only occur for a few seconds, but enough time to create an accident. Apparently you may not even be aware that you have been asleep and in fact could have already suffered several microsleeps whilst driving.

Of course this tends to occur when you have been deprived of sleep, something most of us can suffer from on a daily basis. But the fact you are not even aware you have been falling asleep at the wheel is very worrying as it is very easy to deny that you have a problem and should not be at the wheel of that vehicle.

Long boring drives can also increase the likelyhood and especially at times when you would normally be asleep say at night.
Not sure if the energy drinks can stop this, but the safest thing to do, is not to drive if you are very tired.

We talk here of what happens when you breakdown, and breakdown cover but nothing is more important than your safety and your passengers and pedestrians around you, this could be a killer. Make sure you do not breakdown and only drive when you are alert and have full reactions.
