Foodies have been warned not to scoff too much Christmas pudding, tiramisu and sherry trifle over the Christmas holidays in case the boozy treats put them over the drink drive limit.
Just two slices of the brandy-soaked festive pudding could put drivers over the limit, while two portions of the Italian dessert and three portions of the sherry trifle could have the same effect.
Ten per cent more people were caught drink driving in the run up to Christmas last year than the year before, with 48,800 positive tests on Britain's roads, a freedom of information request has revealed.

Cranberry and port sauce, which can contain up to four glasses of the Portuguese drink, should not be taken in excess of four portions for drivers the research carried out by a car sales company also warned.
Christmas lovers were also advised to avoid more than five portions of Christmas pudding, six glasses of eggnog and seven slabs of brandy butter if they are planning to drive.
Boozy chocolates filled with alcohol such as Bailey's or cherry liquor, should also not be consumed in excess - with drivers warned they should not scoff more than 30.
A limit of 20 mince pies on Christmas day was also set, as scoffing any more could put a driver over the limit.
For those considering a more extravagant Christmas dinner, peppercorn sauce and chicken marsala were also placed on the warning list.
