Calgary speed limit translation


A public service, for those unfamiliar with the speed limit formula used in our city. The basic rule is:

  • left lane: as fast as possible (general rule of thumb is speed limit + 50%)
  • middle lane: speed limit + 25% or so (unless someone is in the left lane, then left lane formula applies)
  • right lane: speed limit + 10% or so, unless someone is in either lane to the left, when left lane formula applies.

You are also encouraged to go as fast as needed in order to pass anyone smaller or less expensive than you. This is especially important in playground and school zones.
