Ford was pulled over because his windows were tinted so much that officers couldn't see in. After approaching the car and speaking with Ford, however, officers allegedly smelled alcohol on his breath.
The 25-year-old receiver subsequently failed a field sobriety test and was placed under arrest.
The case was turned over to the Alamada County District Attorney's Office, which decided Thursday not to pursue charges.
"The District Attorney's Office has declined to file charges against Jacoby Ford," a DA spokeswoman said, according to the Contra Costa Times.
Ford had a decent rookie season in 2010 -- 25 catches, 470 yards, two scores -- but has been scarcely effective since. He missed all of 2012 with a left foot injury.
