Lindsay Lohan has managed to escape serious jail time for her past transgressions, and her guardian angel is still apparently pretty busy -- LiLo is in the hospital after a nasty car accident on Friday.

TMZ reports Lohan was behind the wheel on California's Pacific Coast Highway when her black Porsche collided with an 18-wheeler. The wreck totaled her pricey ride and she, and her assistant who was with her at the time, are at a local hospital where doctors are "performing tests."

Lohan was apparently alert enough to tell eyewitnesses that the crash wasn't her fault.

No word yet on how or if any injuries she might have sustained will affect the shooting schedule for 'Liz & Dick,' the Elizabeth Taylor biopic she's currently filming with 'True Blood' star Grant Bowler.
