An insurance company is calling for the drink-drive limit to be reduced to zero after research showed that a single pint of beer or glass of wine can affect a driver’s performance.

Studies have shown that two- thirds of motorists believe they would be perfectly able to drive after one or two drinks but Privilege Insurance says research demonstrates that just one drink can reduce reaction times, cause loss of concentration, spatial awareness and blurred vision.

Kate Syred, commercial director at Privilege, said: ‘Our research indicated that a significant proportion of motorists continue to drive under the influence of alcohol on a regular basis.

‘This is extremely worrying as even a small amount of alcohol can impair a driver’s judgement and has been shown to increase the risk of accidents.

‘We are calling for the complete eradication of drink-driving and urge motorist to avoid drinking altogether if they know they are going to be driving.’
