Concur States make up their own requirements.

If I recall rightly, in Victoria 10 years ago, I had to simply have a seat belt warning light illuminate for a period of time at ignition on.

Had no relation as to whether it was a warning to the driver, passenger or both. And had no cancellation process is a belt was connected.

It was simply a timed warning light circa 15-20 seconds I think.

If you can, interpret the regs. and get an engineer's advice.
