You don't need to wear a seat belt if you're:
a licensed taxi driver who is 'plying for hire' or carrying passengers
The logic behind this please?
Edit
The seatbelt exemption for taxi drivers, which was last reviewed in 1993, is in place because of concerns that wearing a belt would make them more vulnerable to assault or robbery.
Sheriff Way said it was not certain that Mr McCabe's life would have been saved if he had been wearing a seatbelt, but added he could see no reason why taxi drivers should be exempt from the law.
He said: "The risk to the health and safety of both drivers and passengers which these regulations engender is, in my judgment, wholly disproportionate to the perceived risks to drivers of physical abuse and the like from passengers.
"In my judgment the exemption fosters an attitude of mind amongst taxi drivers that it is their professional 'right' to be exempt and acceptance of this blinds them to their own health and safety."
Sheriff Way said specially designed taxis all now had fully isolated taxi cabs to reduce the risk of assault or robbery and that private hire vehicles could be adapted in such a way.
