Fleet drivers are particularly susceptible to the dangers of driving while tired.

UK-based GEM Motoring Assist is urging drivers to be wise to the dangers of fatigue on journeys. The risks are particularly high among those who drive for their work, says GEM, as they are likely to be at the wheel for long periods, or with tight deadlines to meet in the course of a day.

“Exhausted drivers pose a significant safety threat, to themselves, to their passengers and to others who share the same road space,” said GEM road safety officer Neil Worth. “Fatigue is a major contributory factor in around 20% of road crashes, particularly in the early hours of the morning. However, on long, monotonous stretches of [highways] it’s likely that a much greater proportion of collisions will be fatigue-related.

“Collisions occur when an exhausted driver fails to respond quickly and safely if a dangerous situation arises. These collisions are typically around 50% more likely to result in death or serious injury, as the driver is unable to take avoiding action to reduce severity of an impact.”

Statistics show that those most at risk from a fatigue-related collision include young male drivers, shift workers, truck drivers and fleet vehicle drivers. Around 85% of drivers who cause fatigue-related crashes are male, and more than one third of these are aged under 30.
