Thank you for the post Simon
The definition is for Heavy Vehicle , not Heavy trucks.
"heavy vehicle" means a vehicle, including a bus but not including a school bus, as defined
under the Highway Traffic Act, with a gross vehicle weight of 3,000 kilograms (3 tonnes)
or greater
Here is my point - I was cited braking this sign under Ontario Highway Traffic. Act
Truck Sign
33. A No Heavy Trucks sign shall,
(a) be not less than 60 centimetres in width and not less than 60 centimetres in height; and
(b) bear the markings and have the dimensions as prescribed and illustrated in the following Figure:
could not paste the picture here
If there is no definition for Heavy Trucks I could argue that I was not heavy at the time ,the truck was empty.(It sounds obvious that a tractor trailar is a heavy truck ,on the other hend empty is lighter than a straight truck for example )Could this be a legitimate point if there is no definition ?It sounds very simplistic
Here is the definition from Vaughan BY-LAW NUMBER 284-94
(g) "heavy truck" means a commercial motor vehicle having a weight when unloaded,
of three tonnes or more, or when loaded, of five tonnes or more, but does not
include a passenger vehicle, an ambulance or any vehicle of a police or fire
department;
Here is the one from THE CORPORATION OF THE CITY OF SAULT STE. MARIE
BY-LAW 2008-139
"'Heavy Truck' means a public vehicle that is properly registered to operate on a
highway in the Province of Ontario having a gross vehicle weight as licensed
pursuant to the Highway Traffic Act in excess of 13 tonnes or exceeding 12.5
metres (12.5m) in length but does not include an ambulance, a hearse, a fire
apparatus, a police vehicle or a motorbus."
They are all different .
