I remember getting caught for swerving when I was in my teenage years on Ortigas. The enforcer said that I cut into the next lane and that was defined as swerving. As I was a new driver, I was nervous (that was my first apprehension) and didn't argue.

These days as we drive anywhere around Manila, so many motorcycles weave in and out of traffic. Heck, even pedicabs, tricycles and sometimes horse-drawn carriages would jump lanes and cut you off. Does the swerving rule apply to them as well or is this just reserved for vehicles that have at least 4 wheels?
