These tests by a German automobile association show that driving with a Christmas tree on top of your car can be pretty dangerous.
Who knew that carting home your Christmas tree could be so dangerous?
In this video, testers from a German automobile club find out what happens when a car with a tree strapped to its roof has to stop suddenly.
It isn’t pretty.
The group advises people to secure trees tightly from more than one direction - with straps that ratchet closed.
Putting the tree inside the car is also dangerous, the group says, because it can block the driver’s field of vision.
