While I can't read the yellow font you've used, I'm not surprised the OPP don't believe you since you're using the
Newfoundland Highway Traffic Act.
If you want to try something a little closer to home, go with the Ontario Highway Traffic Act. And yes, you're correct in that you're exempt. Ontario HTA exemptions, under section 106, are as follows:
Quote:
Subsections (2) and (3) do not apply to a person,
(a) who is driving a motor vehicle in reverse;
(b) who holds a certificate signed by a legally qualified medical practitioner certifying that the person is,
(i) for the period stated in the certificate, unable for medical reasons to wear a seat belt assembly, or
(ii) because of the person’s size, build or other physical characteristic, unable to wear a seat belt assembly; or
(c) who is actually engaged in work which requires him or her to alight from and re-enter the motor vehicle at frequent intervals and the motor vehicle does not travel at a speed exceeding 40 kilometres per hour.
