Gov. Jon Corzine?s SUV was traveling at 91 mph just before it crashed last week on the Garden State Parkway, according to an official police account released Tuesday.

The SUV, driven by a state trooper, was 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, police say.

State Police Superintendent Rick Fuentes says in a non-emergency situation, the governor?s drivers are supposed to obey the speed limit when possible. Fuentes adds those drivers are given tremendous discretion and it is unclear if the state trooper driving Corzine did anything wrong.

The SUV crashed into a guardrail on the parkway and left the governor critically injured.

Corzine was headed from Atlantic City to a meeting between fired shock jock Don Imus and members of the Rutgers women?s basketball team in Princeton last Thursday.

The speed limit along that stretch of the Garden State Parkway in Galloway Township is 65 mph.

The state police Motor Vehicle Accident Review Board will investigate the crash. The board investigates all accidents that involve a state trooper.
