David Arquette was just involved in a head-on collision and he's injured ... TMZ has learned.

A witness tells TMZ...David was behind a car that suddenly stopped. David then swerved to the left to avoid hitting the car and went into oncoming traffic. David slammed into a car going the opposite direction.

David was driving a silver Cadillac.

We're told David was on his way to Burbank airport to board a private jet which was going to Las Vegas, for the grand opening of Sugar Factory -- a candy store at the Paris Hotel. He was supposed to attend a party hosted by Kim Kardashian.

UPDATE: He's being taken away by ambulance right now.

seriously, then he swerves into oncoming traffic?

anyway, accidents suck whether you cause them or not. I am carless today because some woman ran a red light and the insurance is taking forever.

I am beginning to hate driving

I refuse to drive into NYC anymore. It's worse than it's ever been.

You always have to keep a safe distance in case the car in front jams on the brakes for whatever reason.

OH NO I LOVE HIM

Dunno why, but that made me laugh out loud.

I do hope your boo recovers quickly, though.

Because you know exactly how I meant "love" and even though you're a classy voice of reason around here, you have an evil side to you. It's showin.

I too hope he recovers quickly.

And I do mean love beyond just I do enjoy his quirkiness overall.
