GRAIN VALLEY, Mo. — Truck speed limiter enforcement has been underway in Ontario and Quebec for about six weeks, but don’t tell the U.S.-based Owner-Operator Independent Drivers Association to get used to it. 

According to the group’s official publication, Landline, OOIDA is still suiting up, legally speaking, for a fight.

OOIDA Director of Regulatory Affairs Rick Craig, speaking on the group’s satellite radio program, said the "battle to try to get this overturned in Ontario and Quebec is certainly not over by a long shot."

OOIDA and some its independent members have for years threatened to challenge the law, which requires all trucks operating in each province to set speed governors at 105 km/h. 

With the rule already in place, Craig conceded that the association is considering legal action as its next step. While it’s difficult to peg OOIDA’s chances, he said he has contacted a handful of law firms for their opinion.

He also confirmed that OOIDA hasn’t ruled out challenging mandatory limiters on the premise that the rule could be a violation of the North American Free Trade Agreement.

Hard enforcement kicked in on July 1. At the time, todaystrucking.com revealed that only a limited number of weigh scales had the appropriate ecm readers to check for speed limiter compliance. How many were in operation across the province, MTO staff wouldn’t reveal.

We also learned that the readers have the ability to check only a limited number of engine settings, even though several more parameters must be properly set in order to ensure trucks are physically limited to 105 km/h (click here for more on that).
