The star boxer failed to show up in Broward County court once again Wednesday ... and the judge issued a warrant for his arrest immediately afterward.

Remember, this ain't the first time Broner's had this problem ... he's been arrested TWICE already for this same issue -- including just last month -- all stemming from a Dec. 2017 speeding incident.

So, where was Broner instead of court Wednesday? Dude has been in Los Angeles -- in fact, he went to the Lakers game on Thursday night. Hey, priorities right?

Cops arrested the 29-year-old for having no driver's license, speeding, no registration or proof of insurance on Dec. 7, 2017 ... but nobody's been able to get him to show in court since.

If/when he ever appears for the traffic offense ... don't be surprised if the judge throws the book at him for blowing off the case so many times in the past year.
