Fresh, clean air for an enjoyable driving experience! Strange things happen in the dead of night. A car leaves a dark and lonely highway at full speed, and slams into an unforgiving tree. On a busy freeway, a car, or worse still, a freight truck, drifts from its lane for no obvious reason and smashes into an oncoming vehicle, with devastating results. More than likely, these crashes were caused by fatigue: drivers either falling asleep at the wheel or so exhausted they made serious - often fatal - driving errors. Fatigue is thought to be one of the biggest killers on roads. 'Loss of concentration' can also be a contributing factor. Slower reaction times, reduced vigilance and poor information processing. It doesn't have to be this way. GST Included
