It all depends on the type of highway and the speed limit signs.
Alberta maintains the fastest speed limit in the provinces; on the Queen Elizabeth II Highway (Highway 2) between Calgary and Edmonton posted limits are 110km/h however the defacto limit by most drivers is typically in excess of 130km/h. The Trans-Canada Highway (Highway 1) between Calgary, Alberta and the Saskatchewan border is also posted at 110km/h with actual speeds mirroring those on Highway 2 to which it is linked.
The speed limit for vehicles merging onto the highway from an on ramp is typically the same as the posted speed limit for that section of the highway.

The off-ramp speed limit on the highway is typically 25-35 mph.

As we know that the duty of highway patrol is to check that someone is not breaking the speed rule at highway. So they are more interested in to know that what is the instantaneous speed of your car because instantaneous speed tell about the speed of a car at any instant. They have no concern with average speed of your car.
