Lindsay Lohan Crash -- Truck Driver Claims Her People Tried to Bribe Him

The guy driving the giant truck that got rear ended by Lindsay Lohan Friday tells TMZ ... LiLo was trying to flee the scene and when he tried to stop her ... her people tried to buy his silence.

Lindsay was driving on the PCH yesterday when she collided with a semi-truck driven by James (we're leaving out his last name). Lohan was trailed by a Cadillac Escalade (which James refers to as a limousine) ... driven by someone connected with her Lifetime movie.

James tells TMZ after the accident, he called 911 as Lindsay and her male assistant got out of the Porsche and into the Escalade. James says the assistant picked up a pink bag, "filled it up with something" and then put clothes on top of it.

James claims the driver of the Escalade was trying to keep him away from the SUV. James says he wanted to exchange info with Lindsay (whom he did not recognize) but it was apparent to him she was about to flee the scene.

James says the Escalade driver offered him money, saying they could "go to the bank" and withdraw some cash.

James says the Escalade driver and Lindsay's assistant put on a full court press: "Him and the guy took me across the street and told me this was some kind of famous person and they didn't want to be in the media. But I'd already called 911 because they were trying to get away from the scene. But they packed a bag and then the limousine driver told me, 'Don't mention the bag to the cops.'"

Steve Honig, Lindsay's rep, tells TMZ, "Lindsay is cooperating fully with law enforcement. She has answered all their questions and provided them with everything they have asked for."
