Anything, and I mean anything is possible on a Russian highway, so we've come to expect the unexpected from our dash cam loving friends.

We can only imagine what caused this boat to come rocketing by someone's car on the side of the road. Faulty tie downs, operator error, trailer hitch security, perhaps? It's really anyone's guess.

Whoever posted the video wryly asked," Is overtaking on the right in a boat prohibited?"
