Interesting piece from James Deakin:

1) Turning Hazard lights on when driving in the rain

You wouldn’t pull the fire alarm unless there was a fire, so why use the hazards when you’re not a hazard? You may think that you’re making yourself more visible, but now there’s nothing distinguishing you from a car that has actually stalled and become a ‘hazard’ on the road that people need to avoid or that emergency crews can identify. That’s why they invented fog lamps, daytime running lamps and headlights/taillights. Use them accordingly. Please. I beg you.

2) Hogging the overtaking lane because I’m on the speed limit naman

Nobody voted you to be the human speed limiter so stop feeling that it is your duty to hold everyone up. The overtaking lane is there for––wait for it––overtaking. So hogging it when you have no intention to overtake is like standing in the only urinal of a crowded public bathroom when you’re not ready to go.

3) Blocking the intersection.

This is one of those things that if it has to even be explained, then you will never understand. And you must never be allowed to drive. Or reproduce.

4) Flashing your lights to tell someone you’re going to either not stop or when you want to turn in front of incoming traffic.

Strange phenomenon this. Many Pinoy drivers feel that when they are about to do something illegal, a quick flash of the lights automatically decriminalizes it. In other words, “I know I am about to turn into oncoming traffic and you’ll have to jam your brakes to avoid me, but I flashed you to tell you I’d do that. So that makes it ok.”

Sometimes they use the hazard for this as well, like when they want to counterflow or park illegally and wait for their passengers and will actually get angry with you if you tell them off because “naka hazard naman ako!” (I flashed you/had my hazard lights on) If that was true, they would have called it the immunity light and Napoles, Revilla, Jinggoy and Johnny would have had all their meetings using it and not be where they are today.

5) Contradicting the traffic lights.

Ok, this is more about the enforcers than the motorists, but it affects us greatly, sometimes fatally. A deputized traffic officer is authorized to override a traffic light, but they must switch it to flashing yellow so that the motorists, who are training their eyes above the intersection, know to approach with caution.
O, yung mga nag-aaway sa paggamit ng hazard light sa ulan, dito kayo magsagutan para di OT sa ibang thread
