Arapahoe County Sheriff Grayson Robinson confirmed to 7NEWS that the troubled star was cited last week for driving without a license and speeding near his home.
The deputy's emphatic notation on the summons says it all: "MUST APPEAR IN COURT."
The 24-year-old Miller was cited at 8:30 a.m. on Sept. 5 for driving 38 mph in a 25 mph zone at 7100 S. Richfield St. in Foxfield, an Arapahoe County suburb.
Robinson said Miller was with his father, who was then allowed to drive his son where ever they were headed.
In a section of the ticket noting the driver's "Attitude" with check boxes ranging from "Good" to "Very Poor," the deputy gave Miller a "Fair."
That's not bad given the hot water the All-Pro player had gotten himself into.
Miller is currently serving a six-game suspension for violating the NFL's drug use policy.
As the NFL was weighing Miller's suspension, he was arrested Aug. 11 at a Centennial gun store when he tried to buy a gun. A background check flagged Miller for having an outstanding arrest warrant for failing to appear in court on an October traffic ticket.
In the October traffic stop, Miller was also ticketed just blocks from his home -- also for driving without a valid license, along with careless driving and no proof of insurance.
Denver Broncos head coach John Fox was disappointed to again be fielding questions about Miller's legal troubles after practice Wednesday.
"Obviously, it's something that we're not happy about," Fox told reporters. "Everybody here has an individual responsibility, not only to themselves, but this organization and this football team. Obviously, it's something we're not pleased about, I'll leave it at that."
Asked if the new traffic violation could impact Miller's NFL suspension, Fox replied: "You'd have to ask the commissioner that. That’s not my lane."
Now, Miller has a mandatory court appearance scheduled for Oct. 28 for both the new traffic violation and the October offense.
