Editing Vehicle size class (section)

===Canada===
Cars are divided into six classes based on interior volume, as shown in the table below. These classes are not defined in Canadian regulations, but by the ''Fuel Consumption Guide'' published by [[Natural Resources Canada]]. An interior volume index is calculated from the combined passenger and trunk or cargo space. Pickup trucks, special purpose vehicles and vans are segmented in their own respective classes.  As most Canadian cars share designs with American cars, Canada's classifications closely mirror those of the United States.

* Cannot start from a dead stop using only the engine
* Cannot exceed a speed of 40&nbsp;km/h on a level paved surface
