I think the most important thing would be enforcement. Is 75K enough? Not near enough for most brokers as it was pointed out. The one nice thing about a broker having it is that someone has confirmed that, at the time of acquiring the bond, they were good to cover the risk for $75K. It's a low bar but one that has to be overcome.
My wish?
That Canada has the same requirement.
That carriers demand each and every broker have it.
That the FMCSA take enforcement on Canadians who broker without it.
That the FMCSA solidify the wording so that every piece of freight that is negotiated to be hauled by someone other than the original entity who negotiated it from the Beneficial Freight Owner(BFO) considers the freight to be brokered. (ie get rid of the interlining).
The rule was put in place to protect carriers, ensure payment, and shield BFO's from a carrier coming back on the BFO for payment (much like our Bill of Lading Act). In the market today, where freight is hard to come by, carriers are lowering their standards to get freight. Sometimes it's so low that there isn't a chance in hell the carrier was getting paid even before the freight was picked up. This website is proof that most carriers don't even look at the address of someone brokering freight. They get into a 'business relationship' with an email address and that's it. I'm all for making it harder to get into this business. Right now all it takes is a gmail address and a laptop to make up some crappy load confirmation sheet.
The tide will turn - it always does. When it does good carriers will request or demand that the broker have a bond or the freight doesn't move leaving the brokers who don't have the capabilities to get a bond in the dust.
Back to the OP. Pentagon had a bond and some people who understood how it works was able to get their money after a bit of work. It's not the worst thing in the world.
