Traffic jams can be caused by a lot of things. If you're driving especially in the northern regions of the Midwest, you can add moose to the possibilities as a new driver video proves.
This just in. Moose are not native to Missouri. However, that doesn't mean that one of these big beasts has never come by for a visit. Back in 1977, a huge moose did indeed make his way into northeast Missouri and it was apparently quite a surprise.
