One thing to note is that here in Maine we have yield rather than merge signs for the onramp:. I don't remember what other states have, its been a few years since I've been out of state.
One of the younger family members is a state Police officer and loves nothing more than to start writing tickets for those drivers who block two lanes to prevent people from moving.
What most don't think about is how much farther back and how many other ramps are effected when we don't use both lanes to the merge point.
Lately I have noticed many signs telling drivers to "USE BOTH LANES TO MERGE POINT" Wonder what that's about?
Yet what about people who decide to pass after that merge point? I see that more often than early merging. On a similar note- just about 2 years ago I headed out after work to look at an attachment I saw on Craigslist. I was on the interstate, about 1/4 way into a 300 mile round trip ride, when I came up behind 2 beer vendor trucks riding side by side at 45 mph. (Speed limit was 75)
At first I thought one was trying to pass the other; but as time went on and traffic piled up behind them I realized they were just playing games. I got on the CB and warned them that I had records their truck numbers and planned to file a complaint; but doubt they had radios.
One pickup driver got so PO'ed that he passed them in the BD lane; not really acceptable in this state. I followed them about 8 miles before we got to 1 lane bridge construction, so they were forced to split up. Once it went back to two lanes the traffic erupted going past them so they were unable to block it again.
I followed through on my threat, and wrote a letter to the company telling the exact place, time, and truck numbers, also mentioning the pickup passing in the BD lane; I got a reply but doubt very much that the drivers even heard about it. If I'd had a dash cam I would have been tempted to go to the SP barracks and show it to them.
