Compare the GVW of the trailer with the towing capacity of the tow vehicle.

The tongue is the part which connects to the tow vehicle's hitch.
Well, that's going to depend on the Gross Vehicle Weight Ratings of the power unit and of the trailer. If it was a tractor-trailer with a trailer that short, then it wouldn't be able to gross 80k - in order to do that, the bridge between the drive tandems on the power unit and the tandems on the trailer must be at least 35 feet - a length greater than the trailer you described. You'd need some specifics about the tow vehicle and the trailer in order for this question to be answered accurately. We only know a trailer length - we don't know the GVWR of the trailer, and nothing about the tow unit, which could be anything from a Class 1 truck (0 - 6000 lbs. GVWR) up to a Class 8 truck (GVWR in excess of 33,000 lbs).
The flasher relay in the tow vehicle needs to be replaced with a heavy duty one.
If it's a commercial use vehicle and the Gross Vehicle Weight Rating of the tow vehicle and of the trailer combine to make a Gross Combination Weight Rating in excess of 26,000 lbs., then yes, a CDL is required.

A 2005 Chevy Cavalier can tow a small utility trailer. A tow hitch has to be purchased and installed on the vehicle before towing the utility trailer.
The tongue is the part which connects to the tow vehicle's hitch.
Probably, the original flasher in the tow vehicle is not designed to carry the load of the extra lights on the trailer.
You can tow some kind of trailer with all most any vehicle,but you need to check your owners manual or with a mechanic or the dealership to find out the maximum weight you should tow.
It is something you can install on to your vehicle to connect a trailer and tow large items such as boats, campers, and even other vehicles (if your vehicle is strong enough).
Not if you can clearly see the lights on the tow vehicle; problem is most cops do not know this and will give you a ticket.
Straight truck is a single vehicle; i.e., there isn't a trailer in tow.
If it has an engine and you can drive it, yes. If not (ie you have to tow it) then no, it is a trailer.
(in the US) If the car and trailer are properly equipped - and the tow vehicle is not over-loaded - and the car, boat, and trailer are properly licensed and registered I believe it is legal anwhere.
