That fender-bender Carlos Santana got into Friday night was no fender-bender -- it was a pretty big crash.

Las Vegas cops were apparently downplaying the seriousness of the accident. But TMZ has obtained a photo of the wreck, and Carlos's car was totaled. The front end is completely crumpled in, and the airbags deployed. In addition, a witness tells the site that he hit not one but two parked cars before his vehicle came to a halt.

One part of the story that was accurate -- it happened because Carlos fell asleep behind the wheel.
