He may be red-nosed, but Rudolph was declared fit to pull a sleigh when he was checked by police taking part in a Christmas drink drive campaign.
Officers were stopping motorists in Holcot last Thursday when they pulled over a car pulling a trailer.
To their surprise, the trailer was carrying a number of reindeer.
PC John Hutchings duly checked the animals to make sure they were safe to pull Santa’s sleigh on their big night on Monday.
Chief Inspector Dave Lawson said: “We want everyone who uses our roads to be safe and that includes reindeer!
“Since the beginning of December, 63 people have been arrested as part of this year’s drink drive campaign and officers will be out throughout the Christmas period to continue the operation.
“We don’t want to ruin anyone’s Christmas but I have to emphasise that it is the motorists’ responsibility to make sure they are not over the limit when they get behind the wheel. Our message is clear – if you are driving don’t drink alcohol.
“Now is the time to get organised and decide who is going to be your nominated driver or who is going to pick you up if you are planning to have a drink.”
Northamptonshire Police have asked the Telegraph to point out that no reindeer were actually breath tested as part of the campaign.
