Where to connect the battery breakaway cable?

FlaDon,

No arguement, but there is a difference in the CFRs from CMVs to nonCMV braking requirements. For non-CMVs, the requirements are mostly left up to the individual states because the ICC could not regulate IntRAstate regulations. There is often cross-talk between CMV and non requirements, so it's important to read the whole section to understand if the regulations apply to both CMV and non vehicle types.

When the regulations say "lock", in terms of break-away, they mean simply that the brakes must fully apply, not that the tire must skid. That's all I was tyring to convey.

True. But the manufacturer can never tell when built or used if it will be commercial or non-comm use. If you put the "meets DOT requirements " on it, it better meet the Fed rules or they could be taken to court by some business owner. And I agree with you on the brakes locking, it isn't meant to be to skid the wheels. You lose control of a skidding wheel while one that is still turning is controllable. A skidding trailer can jackknife. Ask all the semi drivers that have had their trailer brakes lock on a wet road. It doesn't take long for the trailer to go sideways. That's why the Feds wrote it as applied instead of locked.

If it meets the Fed rule, the states are pretty much stuck as to what the max they can enforce is on anyone from outside that state. Intrstate drivers is a whole different can of worms
