Tiger Woods Search Warrant Based on Possible Evidence of Reckless Driving

The L.A. County Sheriff got a search warrant to seize the black box in the vehicle Tiger Woods crashed ... because a judge believed there was probable cause to believe a crime may have been committed, and law enforcement sources say the possible offense is misdemeanor reckless driving.

Multiple law enforcement sources tell TMZ ... the search warrant prepared by the Sheriff's Dept. outlined details of the crash that left Tiger badly injured. Some of the items go to the heart of the warrant -- establishing probable cause -- the fact there were no skid marks, the objects struck by the SUV before it came to rest, the fact it was a single-vehicle crash, Tiger's horrendous injuries as well as damage to the vehicle and apparent excessive speed.

Our sources say the words "reckless driving" are not mentioned in the warrant. In fact, our sources say no specific crime is listed in the warrant. Nevertheless, a judge is prohibited from signing a search warrant unless there's probable cause of a crime. That's the essence of the 4th Amendment to the Constitution.

Our law enforcement sources say one of 2 things occurred ... either a member of the Sheriff's Dept. went into the judge's chambers to discuss the warrant -- something that is frequently done -- and mentioned reckless driving, or the judge simply looked at the documents and determined there was probable cause of possible reckless driving. Nevertheless, our law enforcement sources say examining the black box for possible reckless driving was the object of the search warrant.
