Business drivers are most at risk from driver fatigue, says the AA, which is calling for employers to be more aware of the dangers that their staff face on the road, writes David Duffy.

Responding to the launch of a Government campaign to increase awareness of the dangers of driving while tired, Andrew Howard, AA head of road safety, said: "Business motorists are under pressure to meet deadlines and appointments, which means that they often drive too far, for too long.

"As a result, they, not holiday drivers, are those who are mostly likely to suffer from fatigue.

"Company cultures need to change. People must realise that no meeting, deadline or bonus is worth risking a life for.

"They should set more realistic schedules, and be encouraged to stay overnight on long trips."

The AA says that all drivers should note the dangers of not taking regular breaks.

It urges motorists to:

* Avoid driving for more than two hours at a time without stopping

* Stop for at least 15 minutes when they take a break

* Stop somewhere safe, like a motorway service area. Never use the hard shoulder as a resting place: it is for emergency use only

* During the break, take a short nap or drink two cups of strong coffee. Fresh air, exercise or turning up the radio may help for a short time, but are not as effective

* Avoid heavy meals or alcohol before setting off

* Make sure they are fit to drive. Don't undertake a long journey (longer than an hour) if you feel tired;

* Try to avoid undertaking long journeys between midnight and 6am, when natural alertness is at a minimum; and

* Keep the car well ventilated.
