A Connecticut truck driver has been fined $500 and had his license revoked over a crash that killed a police officer on New York's Long Island Expressway.

John Kaley, of New Britain, Conn., pleaded guilty Thursday to a misdemeanor charge of reckless driving stemming from the February 2011 crash that killed Nassau County Police Officer Michael Califano.

The plea came after a prosecutor said it was unlikely she could win a conviction for criminally negligent homicide.

Prosecutor Maureen McCormick says Kaley's flatbed truck slammed into a cruiser with its lights flashing after Califano stopped a motorist in Old Westbury. Witnesses said the truck had weaved through traffic for two miles.

McCormick says prosecutors would have found it difficult to prove allegations Kaley had fallen asleep.
