The Fight Club star was riding through busy Los Angeles traffic on his motorcycle when he lost control while attempting to manoeuvre between cars, reports TMZ.com.
He is said to have accidentally clipped a parked vehicle with his handlebars, and toppled to the ground after swerving to avoid hitting another car stopped at a red light.
Pitt's mangled motorbike wouldn't start after the incident, and a tow-truck took the star and his machine home.
