An analysis of over 4500 accidents by the AAA foundation for traffic safety in Washington has found that even mild drowsiness can result in a 30% increase in the risk of a road traffic accident and the possibility of a prosecution for dangerous driving.

Drivers who lose one or two hours of sleep the night before driving  risk being involved in a road traffic accident and, it is claimed that moderate sleep deprivation causes dangerous driving just as much as being drunk, because reaction times get longer.

It is thought that at least half of the cases of causing death by dangerous driving involve the fault of tired drivers.

Motorists should take extreme care to avoid whilst driving overtired. Should they be involved in a road traffic accident they could very well face a prosecution for dangerous driving or, in the worst case scenario, a prosecution for causing death by dangerous driving.
