Road safety campaigners are calling for firms to take a tougher line with workers who get behind the wheel while under the influence of alcohol or drugs.
The call by charity Brake for a zero-tolerance approach comes after a new survey found that only 44% of the companies which have staff who drive a vehicle for business purposes would sack a worker who had been caught drink driving.
More than half admitted that they never test their workers for drugs or alcohol while proportions of only 50% and 47% said they educate their drivers about the deadly dangers of drink-driving and drug-driving.
Almost two-thirds (62%) of the employers polled by Brake and the Licence Bureau did say disciplinary action would be taken against staff found to have illegal drugs or alcohol in their system - but less than a third (30%) said it was a sackable offence.
Brake says it wants to see firms adopt tougher policies in a bid to make sure employees are sober and alert when they drive a vehicle for work. It also wants employers to ensure their drivers have adequate eyesight and are not over-tired or stressed before taking to the road.
