Before driving a car with a trailer, it must be hitched to the ball hitch of the car. Each time, attach a safety cable that is attached to each car trailer or caravan. When connecting the trailer to the car, remember to attach the cable to a separate holder and not directly behind the tow ball. This method of attaching a car trailer will prevent the cable from clearing away from the towing car in the event of unhitching of the trailer while driving. Then make sure that the car trailer is correctly attached to the towing vehicle's tow hook (usually a passenger car or van). The ball head holder should be in a horizontal position. The lever lock pawl should be in the "locked" position. Perform a manual attempt to detach the drawbar from the towing hook to check that the trailer hitch ball is properly fitted. In the next step of attaching the trailer to the passenger car, connect the trailer's plug with the ball hitch socket. When disconnecting, do not pull directly on the cord. Finally, remember to always raise the support wheel attached to the drawbar of the trailer before every journey with a car or trailer on the road.
Before driving with a car trailer, check wheel bolts for tightness and tighten them with a torque wrench, if necessary. It is important to tighten the wheel bolts every 500 kilometers. When driving with a car trailer, the coating of hubs and rims will wear and the screws may loose. For this reason, you should not forget to tighten them.
Checking the lights in the car trailer before towing
Every time before towing a car trailer make sure that the lighting functions properly. Of course, all lights are checked by connecting the plug to the tow hook socket. Errors in the functioning of lighting in a car trailer can be checked using a suitable device or a second vehicle.
Possible sources of lack of lighting in the car trailer are: the plug has not been properly connected to the socket; the trailer lighting plug is dirty or tarnished; the plug cable is corroded or torn out; damaged bulbs; contacts in lighting are corroded as a result of moisture.
Lack of lighting in the car trailer can also be caused by defects in the towing car: defect of the socket to the lighting plug; for some cars, the electrical installation is constructed in such a way that the fuse blows - it is recommended to install a more powerful fuse; a detailed description of the electrical installation of all car trailers can be found on the attached wiring diagram and it contains all the elements making up the electrical installation in the trailers (nominally Neptun car trailers).
Questions and answers (FAQ) about car trailers
Can I register a car trailer of my own production?
Generally yes. You can register your own car trailer. However, for one piece it is completely unprofitable. Normalization of regulations in the European Union has led to the fact that the cost of legalizing a trailer design, obtaining approval and inspection costs for placing a trailer in service for one piece is so high that it is unprofitable for a private person. If you want to buy a trailer for your own needs, the best solution would be to buy it in any car shop, where the trailer already has all the documents and is ready for registration!

One of the structural elements of every car trailer that is exposed to standard wear is a ball hitch. Here, too, you should remember to regularly clean the ball hitch to keep it functioning as long as possible.

In the case of zinc coating defects, chips, pitting, degrease, clean, dry and apply 2 or 3 layers of cold galvanizing agent (e.g. aerosol zinc). All metal elements of the car trailer are protected by a layer of zinc. The goal is corrosion protection. Because zinc reacts for a long time with oxygen in the air, some surfaces darken. This is the result of oxidative processes and at the same time it is not a defect. The protective layer is not resistant to acids, salts and some chemical agents.
