> I'm not usually one of the slow drivers and I do get annoyed at the slow drivers when I can't pass them but I will still keep my distance and avoid trolling them with horns, lights or otherwise. The road is for everyone and some will be slower than me and some will be faster.
It's certainly their right to drive slowly, but in Washington state it is not their right to delay others:
> Slow-moving vehicle to pull off roadway.
> On a two-lane highway where passing is unsafe because of traffic in the opposite direction or other conditions, a slow moving vehicle, behind which five or more vehicles are formed in a line, shall turn off the roadway wherever sufficient area for a safe turn-out exists, in order to permit the vehicles following to proceed. As used in this section a slow moving vehicle is one which is proceeding at a rate of speed less than the normal flow of traffic at the particular time and place.
