Reindeers in Norway are getting help with road safety - by wearing bright reflective collars and antler tags.
The country wants to make it easier for drivers to spot Santa's helpers on the roads and cut the number of accidents.
It's reckoned 200,000 reindeers live in Norway, but around 500 of them are killed each year on the roads.
Reflective tape and reflective spray has been used to help reindeers before, but they didn't work well. It's hoped this new project will be the answer!
