Ontario to limit truck speed

McGuinty Government Makes Speed Limiters Mandatory In Ontario

Ministry of Transportation

The Ontario legislature today passed a bill mandating speed limiter use on most large trucks to cap speeds at 105 kilometres per hour to reduce pollution and improve road safety.

A speed limiter is an electronic device that caps the top speed of a vehicle. Speed limiters are proven to lower maintenance costs and improve fuel economy.

In Ontario, transportation accounts for more than 30 per cent of the province's total greenhouse gas emissions. As part of Ontario's plan to fight climate change, speed limiters will help reduce greenhouse gas emissions.

The use of speed limiters could be implemented as early as fall 2008, followed by a six to 12 month education period.

Quick Facts

  • Mandatory speed limiters in Ontario will reduce greenhouse gas emissions by as much as 280,000 tonnes - that's like taking 2,700 tractor-trailers off the roads every year. It will also save about 100 million litres of diesel fuel per year.
  • Speed limiters are mandatory for all trucks manufactured after 1995 with an electronic engine operating in Ontario, regardless of where they come from.
  • Most trucks built in the last decade come equipped with speed limiter technology.

“Speed limiters slow down trucks, help keep our roads safe and reduce greenhouse gas emissions. This is another step forward in our plan to build a cleaner, greener and stronger province.”

Jim Bradley

Minister of Transportation

“The mandatory activation of speed limiters is an effective way for the trucking industry to further contribute to safer highways and to reduce greenhouse gas emissions. The fuel savings from speed limiters will also help to moderate the increases in operating costs from escalating diesel fuel prices. This is the right thing to do.”
