Fleet managers should take a zero-tolerance approach to tackle drink and drug-driving, says new guidance from Global Fleet Champions campaign.

The latest guidance explores how fleet managers can promote safe and sensible decision-making within their workforce.

It argues that fleet managers have a legal, moral and social responsibility to ensure their drivers remain alcohol and drug-free at the wheel.

Sarah Plumb, senior fleet officer at road safety charity Brake, said: 'Ensuring the safety of your fleet goes further than vehicle maintenance; the person behind the wheel also needs to be fit for the road.

'A good road safety strategy should establish clear standards of behaviour and should promote a zero-tolerance approach to driving under the influence of any drugs or alcohol. This guidance is a valuable resource for anyone who manages people who drive for work.'
