Conrad Hilton Car Accident -- Avoids Serious Injury in Terrible Crash

Conrad Hilton, the younger brother of Paris Hilton, was involved in a major car crash over the weekend ... but TMZ has learned he emerged without any major injuries.

According to the California Highway Patrol, Hilton was driving in Palm Springs Saturday afternoon when he clipped the back of another car while trying to change lanes. CHP says his car then hit the rear of a tractor trailer before coming to a rest on the side of the road.

Police say paramedics had to use the ol' jaws of life to free Hilton from his car. As bad as that sounds, ours sources say Hilton suffered a fracture in his hand, a few cuts and bruises, but no major injuries.

According to the CHP, drugs and alcohol were not a factor, but Hilton was observed to be speeding before the crash. Police say before the crash, another driver called 911 to report Hilton's reckless driving and an officer tried to pull Hilton over, but lost sight of him.

This isn't Hilton's first major crash. Back in 2011, he smashed his car into a parked car while speeding down a residential street in Brentwood.
