State by State RV and Towing Laws

If you’re traveling between states, make sure you learn the towing laws of both states as laws can be quite different from one state to another. However, most states have very fluid towing laws and the laws are not enforced too stringently. There are a few general rules pertaining to trailers that carry higher weights that require breakaway switches that automatically engage in case the trailer disengages from the car. Other than that, there aren’t many laws absolutely set in stone because most laws are aimed only at truckers who drive large big rigs.
