Wheelbase and Governed Trucks

Second question first.

Ontario and Quebec are the only provinces that have speed limiter laws. Trucks are required to have a "hard" limiter (cannot be adjusted by driver) set to a maximum of 105 kilometres per hour (65.25 mph).

Officially, the maximum legal wheelbase for tandem-drive tractors for TAC-compliant vehicles (comply with vehicles standards set by the Transportation Association of Canada and outlined in the Commercial Transport Regulations) is 6.2 metres (244 inches). This can be exceeded in most (all?) jurisdictions by permit. For example, in BC you can permit a longer wheelbase tractor (to accommodate Americans running up to Alaska) so long as you don't exceed the maximum length (23 m / 75.5 ft), but it negates any other permit so no over length, over width, over weight, etc.

BC SPECIALIZED VEHICLE SIZE AND WEIGHT GUIDELINES AND PERMITS

5.3.7.A. Long Wheelbase Truck Tractors Exceeding 6.2 m
Restrictions:

Non-TAC combinations (e.g. container trailers with added axles such as jeeps and
boosters, two vehicle combinations including logging truck/pole trailer or long
wheelbase truck tractors) are restricted to 23 m overall length.

Some jurisdictions may allow long wheelbase tractors without a permit so long as you don't exceed the maximum length. There has also been some discussion in various jurisdictions regarding changing this regulation, but I admit I am not entirely up-to-speed on this as it has been a non-issue as none of my trucks ever exceeded 6.2 m. It is best to check with each provincial authority as applicable.

 

And the first time you roll by a scale in Ontario, they will likely throw the 'puter on you to make sure you have the governor set where it is supposed to be. Although I still see plenty of trucks doing 110 and beyond.

 

Hmm... I've had mine checked twice in the past year and I live here.

 

I believe it is $250 in ON and $350 in QC.

 

I wouldn't know, I haven't been in a truck that can break 102 in a decade! LOL!!

 

Most highway trucks up here are 244" or less. No matter the tractor wheelbase, your max length cannot typically exceed 75 feet. Ontario and Quebec are the only provinces with a speed limiter law on the books, and it must be set to 105 km/h or lower (65mph). In those two provinces, it's not that big a deal, since the speed limit is 62 mph (100 km/h), but to those of us who live in provinces with higher speed limits (like 110 km/h in New Brunswick) it seems pretty stupid. I don't drive that fast anyway, but it seems dumb that just because I run in Ontario and Quebec, I can't drive the legal speed limit in my home province, or the prairie provinces without having my speed limiter reprogrammed.
