“In Ca. all cars must have seat belts regardless of age.”
First off, I acknowledge the original poster’s question involved seat belt requirements in Canada, and therefore apologize for drifting off-topic. Second, I also apologize – in advance - for the length of this response.
However, I thought the above statement (regarding seat belt laws in California) interesting, inasmuch as I just finished installed seat belts in the rumble seat of my coupe in response to my daughter and son-in-law’s repeated requests to include our grandsons in the next parade our club participated in. I had long resisted these requests, not because I didn’t want to further the younger generation’s interest in and enjoyment of Model A’s, but out of pure fear of something happening to my children’s children while doing so, a fear exacerbated by the 'rambuctioness' of 10- and 6-year old boys whose unbridled “Hey, watch this!” approach to life seems singularly unsuited to trips in a Model A rumble seat, restrained or not.
Furthermore, the age of our youngest grandson raises the question of the use of child restraint seats.
Here are the relevant sections of – for those in California (and for those who might want to visit California in their Model A) – the California Vehicle Code (with some abbreviation for clarity):
Section 27315(f) – Mandatory Seat Belt Law: An owner of a motor vehicle…operated on a highway shall maintain safety belts in good working order for the use of the occupants of the vehicle...This subdivision, however, does not require installation or maintenance of safety belts if it is not required by the laws of the United States applicable to the vehicle at the time of its initial sale.
Section 27360 – Child Passenger Restraint System, Requirements for Children 8 Years of Age or Younger: Except as provided in Section 27363, a parent, legal guardian, or driver shall not transport on a highway in a motor vehicle…a child or ward who is under eight years of age, without properly securing that child in a rear seat in an appropriate child passenger restraint system...[This] subsection does not apply to a driver if the parent or legal guardian of the child is also present in the motor vehicle and is not the driver.”
Section 27363 – Exemptions: (a) The court may exempt from the requirements of this article any class of child by age, weight, or size if it is determined that the use of a child passenger restraint system would be impractical by reason of physical unfitness, medical condition, or size.
(b) In case of a life-threatening emergency, or when a child is being transported in an authorized emergency vehicle, if there is no child passenger restraint system available, a child may be transported without the use of that system, but the child shall be secured by a seatbelt.
(c) A child weighing more than 40 pounds may be transported in the backseat of a vehicle while wearing only a lap safety belt when the backseat of the vehicle is not equipped with a combination lap and shoulder safety belt.
(d) [A] child or ward under eight years of age who is four feet nine inches in height or taller may be properly restrained by a safety belt…rather than by a child passenger restraint system.
(e) [A] child or ward under eight years of age may ride properly secured in an appropriate child passenger restraint system meeting applicable federal motor vehicle safety standards in the front seat of a motor vehicle under any of the following circumstances: (1) There is no rear seat; (2) The rear seats are side-facing jump seats; (3) The rear seats are rear-facing seats; (4) The child passenger restraint system cannot be installed properly in the rear seat; (5) All rear seats are already occupied by children seven years of age or under; (6) Medical reasons necessitate that the child or ward not ride in the rear seat.
(f) Notwithstanding subdivision (e), a child shall not be transported in a rear-facing child passenger restraint system in the front seat of a motor vehicle that is equipped with an active frontal passenger airbag.
Sorry for the long – and somewhat off-topic – post.
