"...Motorists should use horns only in emergency situations or face a P500 fine..."

I'm not sure what to think of this. I find those who excessively honk their horns very annoying. But in my opinion, there are some drivers who are just begging for a good honking :D Or maybe I just got used to Philippine driving. Dunno how it is in other countries regarding this issue.

I like the news about the lighting devices though.
