Fail! This is how you should NOT exit a car wash…

CCTV footage from Montana in the United States shows a minivan driver making rather a dramatic exit from a car wash.

The video shows what looks to be a second-generation Toyota Sienna pulling out of the car wash.

But rather than successfully negotiating the tight turn, the Toyota driver heads clear off an embankment, flipping the vehicle onto its roof and flattening a fire hydrant in the process.

Well, at least the underside of the minivan had a good wash, too…
