Irritating pinoy drivers' Ugali

[Radical!]

This laws doesn't apply in the Philippines but, Here's what we use here in Washington State. (RCW - Revised Code of Washington)

RCW 46.61.100
Keep right except when passing,
(1) Upon all roadways of sufficient width a vehicle shall be driven upon the right half of the roadway, except as follows:

(a) When overtaking and passing another vehicle proceeding in the same direction under the rules governing such movement.

(2) Upon all roadways having two or more lanes for traffic moving in the same direction, all vehicles shall be driven in the right-hand lane then available for traffic, except (a) when overtaking and passing another vehicle proceeding in the same direction, (b) when traveling at a speed greater than the traffic flow, (c) when moving left to allow traffic to merge, or (d) when preparing for a left turn at an intersection.
(3) This article is for trailer trucks (I think it doesn't concern us)
(4) It is a traffic infraction to drive continuously in the left lane of a multilane roadway when it impedes the flow of other traffic.

Here is the amendments for that rules:
Legislative intent -- 1986 c 93: "It is the intent of the legislature, in this 1985 [1986] amendment of RCW 46.61.100, that the left-hand lane on any state highway with two or more lanes in the same direction be used primarily as a passing lane." [1986 c 93 § 1.]
