Between 3,000 and 5,000 accidents involve reindeer each year, incidents which are "much deadlier for the reindeer than for drivers."
"Reindeer graze free in nature and are quite often hit by cars," Anne Ollila, head of the Reindeer Herders' Association, told Mashable. "We want to find solutions to avoid this."
Finland's Reindeer Herders' Association is currently testing two reflective sprays on 20 of the animals: a more permanent spray for antlers and a washable one for fur.
The spray will glow when a car's headlights shine on it.
"The spray is being tried on their fur, but it is maybe more effective on their antlers because the reflection can be seen in every direction," Ollila told Finnish broadcaster YLE.
