I believe all tow vehicles exceeding a certain weigh are required to have a braking systems in place. These range from vacuum, surge or electric among others. In addition, there is usually a break away cable that engages the tow vehicle brakes if it should separate while being towed.
For good reason. I was just towing my brand new Cargo Mate enclosed trailer when it jumped off the hitch ball on the highway. I wouldn't even want to know what would have happened without safety chains or a breakaway cable (which didn't activate since the chains held it). Turns out the coupler is either bad or out of adjustment. Scared the bejesus out of me. I have been towing for over 30 years and never had something like that happen.
