The yellow median on the street means traffic is two-way. When it’s white, traffic is one-way. It’s one of many standards written in land transportation manuals and taught in driving schools.
In Philippine roads, however, white or yellow lines divide two-way highways. Motorists just know the lines divide the roads; it’s up to you to figure out if traffic is one-way or two-way.
Many drivers don’t know or don’t care about medians, signs, or traffic lights. “STOP” is a suggestion. “YIELD” is whatever. A red light may mean green; green means no need to brake.
No wonder driving is dangerous in the Philippines.
