The superintendent of the state police says Gov. Jon S. Corzine's SUV was traveling at approximately 91 mph seconds before it crashed into a guardrail on the Garden State Parkway, critically injuring the governor last week.

The speed limit along that stretch of the parkway in Galloway Township is 65 mph.

The state trooper-driven SUV carrying the governor from Atlantic City to Princeton Thursday evening was traveling in the left lane with its emergency lights flashing when another vehicle tried to get out of its way. Instead, it set off a chain reaction that resulted in an accident leaving the governor with life-threatening injuries.

The state police released the first official account of the ongoing investigation Tuesday.
