Any Ban on National Highways or any other road should have prohibited road signs to inform the driver according to the Vienna Convention on Road Signs and Signals.
The Philippines is a Contracting party to the Vienna Convention on Road Signs and Signals. The Vienna Convention on Road Signs and Signals was ratified by Presidential Decree No. 207 (1973), thus adopting and making the convention “part of the law of the land.”
So if you get stopped and are told you are prohibited from that road, ask them where is the road sign that prohibits you from using that road. If there is no road sign then they can’t expect you to know you were prohibited and they themselves are not following the law.
If they say there was a sign a few intersections back this is not good enough as the clearly states that the signs should be repeated at each intersection or the prohibition no longer applies.
The road signs should also be reflective or illuminated.
I am sure there is no LGU that would knowingly fine you without following the law themselves. It is up to us to inform them that any Ban on National Highways or any other road requires them to put up reflective prohibited signs at every intersection.
