Bring those rulings, your licence, and any proof that you might have that you were carrying a fare with you at the time.
I'm sure you know this, but the exemption allowing cabbies to drive without a seatbelt is because of robberies. Thieves would grab the seat belt to pin the cabbie in the seat while threatening them with a weapon. Sheesh... even I knew that.
Anyway, on the day of trial, check in with the Prosecutor and explain that you were a cab driver carrying a fare. Present the regulations at that time. In the highly unlikely event that the Prosecutor insists on a trial, when it's your turn to ask questions:
You: "Constable, when you stopped the defendant (me), was he driving a cab at the time?"
Officer: "Yes."
You: "Was the defendant carrying a fare at the time?"
Officer: "Yes."
You: "Did the defendant point this out to you?"
Officer: "Yes."
You: "Did the cab driver have a valid taxi licence?"
Officer: "Uhh....."
You: "Are you familiar with regulation 613, which covers seat belt exemptions?"
Officer: "Yes, I am."
You: "Really? I have it here... please read the following paragraph..."
After he does that, tell the court you would like to make a motion of non-suit, and the case should be tossed.
