he forgot to mention that the left lane is the slow lane, and overtaking lane is the inner lane (unless occupied by a parked tricycle, jeepney, taxi, pedestrian or shanty) and the opposite lane, even if there is a vehicle on the opposite lane. Pwede naman kasi tumigil yung oncoming vehicle habang nag oovertake ka.

Also, that jeepneys can stop in the left lane to unload passengers. And in a 2 lane road going in the same direction, the white broken lines separating the 2 lanes acts as a guide for the driver to follow by putting the car in between the broken lines.
