Stan, I have to agree with Bill. It’s not a silly rule. Here among the Oregon Coast Range are several state highways that follow rivers and are thus very curvy in sections. The Highway Dept. puts slow-vehicle lanes or pull-offs wherever possible, and I try to use them. The curves are usually posted to yellow cautious speeds, which in my personal practice are ideal for our coaches.
The problem is that most cars can negotiate them at much faster speeds, and many get perturbed to the point of making ill-advised passing attempts. Thus the coast highway head-on accident reporting I hear almost daily on the news here. When 4-5 cars necessarily back up behind me, if not before, I try to utilize the next available pullover, often raising the copilot’s anxiety level in the process. Because there are many out there who aren’t so charitable and focus only on their own progress rather than the public’s overall safety, such laws are necessary. I appreciate the legislator that long-ago brought the rule to fruition in Oregon.
Now whether everyone in a slow vehicle, huge truck or 5th wheel, heeds the law is another story, unfortunately.
