Who polices Union
Union is the smallest town in Connecticut by population. It has no municipal police department and no resident trooper. Coverage comes from Connecticut State Police Troop C, and nearly every arrest in Union is an Interstate 84 stop.
In practice this means almost nobody arrested in Union is from Union. If you were pulled over on the interstate somewhere between Massachusetts and the rest of Connecticut and the paperwork says Union, that is why. The town line is where the stop happened, and it decides which court hears the case.
Where your case goes
Union cases are prosecuted at Rockville Superior Court, GA 19, in the Rockville section of Vernon, a good distance down the interstate from where the stop happened. The court page covers parking, the docket, and where to check in.
If troopers released you, the date is on your paperwork. If you were held, you go to court the next business day. If you were passing through from out of state, the date is still real, and ignoring it turns a traffic case into a warrant.
After the arrest
Almost every Union arrest starts on the interstate, and how it ends depends on the bond. Released on a written promise to appear or after posting, you leave with a date. Unable to post, you are held until court the next business day, when a judge reviews it. The bond and bail page covers the options, including what a bondsman actually costs, and the arrest page covers booking.
If you were passing through, the temptation is to treat the paperwork as someone else problem once you are home. Do not. A missed date becomes a warrant and a separate charge, and it follows you across state lines.
Say nothing about the stop in the meantime, on any recorded line or to anyone who was in the car. A family violence arrest, rarer here but not unheard of, goes to court the next business day with a protective order issued at that appearance. The arraignment page and the what to expect page cover what follows.
Common charges in Union
Union arrests are overwhelmingly highway cases, which puts DUI and drug possession at the front of what GA 19 sees from the town, frequently arising from the same stop. Larceny and shoplifting, assault, and domestic violence and family violence appear far less often simply because there are fewer residents. For a first offense a diversionary program ending in dismissal is often available, including to someone who lives out of state.
