Lohan's Ride Smashes into a Giant Door

Hours after she finished up her alcohol education class yesterday, Lindsay Lohan was already getting smashed at a Hollywood bar ... but this time it wasn't her fault.

Linds was being driven out of Sky Bar when once again, she fell victim to her bad car-ma -- her driver crashed into one of the bar's impossible-to-miss, 30-foot tall, mahogany doors.

Nobody was hurt and Lohan eventually rolled out ... but pay attention to the beginning of the video -- the "boom" is pretty damn hard to miss.
