How should I pass another Cyclist on a bike lane or on a shared road? 

The same traffic rules apply. If you are a cyclist, check behind you to make sure no vehicles are on the left lane. Use your hand signals to let other vehicles know your intentions. When passing the other cyclist, you can use an audible signal such as a bell or voice signal to let the other cyclist know you are "Passing". This avoids surprises. If you are a motorist you will be traveling on a separate lane. Remember to be aware of bicyclists traveling on the bike lane, especially when making a right turn. Signal to let all vehicles know your intentions. Be aware that bicyclists may travel outside of the bike lane if necessary.

On a shared road? If you are a bicyclist, the same traffic rules hold true for passing bicycles or other vehicles on a shared road. If you are a motorist remember that the bicycle is a vehicle too and has the right to occupy the full lane under certain conditions. You must pass on the left lane following the normal traffic rules.

Shared roads are not striped. A bicyclist and motorist can travel on the same lane. The striped lane separates a motorist lane and a bicyclist lane. In both cases, a bicyclist can take the full traffic lane if road hazards or concerns warrant it: debris or busy driveways are an example (PowerPoint File - 205K file size).
