A video posted to Facebook shows a traffic court judge in the United States chasing a driver through a busy intersection.
The video shows the judge stopping the car, hitting it, and then speeding away.
The driver’s face is obscured, but he can be seen on the dash camera recording.
The judge can be heard saying “Get your ass out of here!” in the background.
The court’s website says it is a “free traffic court service for drivers in the state of Texas.”
The officer is identified by the headline “The Traffic Judge”.
It’s unclear whether the video was recorded at the court, a video camera, or both.
It’s not clear who recorded the incident.
A spokesperson for the Texas Department of Public Safety said the officer involved was responding to a report of a vehicle involved in an accident and stopped the vehicle after the driver refused to exit the vehicle.
The officer was placed on administrative leave, which is standard procedure, and was later removed from the court.

The motorist then runs away.
He’s wearing a protective vest, a backpack, and a helmet, according to witnesses.
Police later found a black Toyota Corolla in the suspect’s driveway.
A police report said the car had “traffic violations” and was impounded.
Officers later found two knives in the car.
A search of the car revealed no weapons, but it did contain “a variety of drugs including marijuana, cocaine, methamphetamine, Oxycontin, Oxycodone, and marijuana”, according to the police report.
In Texas, police can use a “flash bang” on a person if they believe that the person is a flight risk.
Other states use similar tactics, but are not widely used, according.
At least 15 states and the District of Columbia have passed laws requiring police to use flash bangs to immobilise or stop suspects in traffic stops, according the American Civil Liberties Union.
Authorities are also required to have body-worn cameras in their vehicles.
