An ACCIDENT on the bridge Garver

In San Fierro, Garver bridge (in the second city, on grey road bridge) was an ACCIDENT. The driver lost control, crashed into a fence, flew out of the windshield and, by some miracle, manage to seize the bumper and hang on it. Passing by the bikers already called an ambulance and the police, it remains only to figure out how to save him.
Everything that exists in a script, you can see in the screenshots.
