Toronto Star. The Ontario government is making it mandatory for all large commercial vehicles to use speed limiters, according to Transportation Minister Donna Cansfield.
The speed will be capped at 105 kph (65 mph)—5 kph above most speed limits to give truckers an opportunity to pass slower moving vehicles.
In November 2005, Ontario trucking companies met at an annual general meeting and adopted a policy that called on the government to require all trucks that drive into, out of and within Ontario to use speed limiters.
The Ontario Trucking Association says all trucks built in the last decade are already equipped with speed limiting technology and they estimate that speed limiters will save a typical tractor trailer 10,500 litres of diesel fuel every year.
They also expect speed limiters to reduce the number of severe accidents involving large commercial trucks.
