ROAD safety charity IAM is urging motorists against getting behind the wheel after trying to guess how much alcohol they have consumed.
Chief examiner Peter Rodger said: “This time of year brings with it brandy pudding, mulled wine and Christmas parties. If you’re heading out for a few drinks, make sure you have planned your journey home before you set off.
“Don’t try to calculate whether or not you have consumed enough to tip you over the drink-drive limit.
“Drinks poured at home are usually larger than pub measures - don’t underestimate how much you’ve had.
“If you drive to a party and drink more than you expected to, don’t risk it. Book yourself a taxi.”
