you are correct but there are other reasons for using it....Flashing can indicate the intention to overtake or pass another driver, or to signal a driver who has just overtaken that he or she can now return to the original lane. Flashing can request or insist that a leading driver speed up or change lanes to get out of the way of a faster following driver.
I like to use it on highways at night when there is very little traffic....I have had a vehicle or two over the years drift into my lane as they are passing..inattentive drivers don't always realize there is someone coming up and around them....this alerts them that you are coming up beside them...its a safety feature. And yes it is also to help guide truckers with long loads of when they have cleared the vehicle in front of them.
Both are intended as a courtesy gesture.
Right or wrong, here's how I do it:
-trucker passes me on the left, courtesy flash to him when he's clear to come back in my lane. Results in a "thank you" blinker from the big truck quite often
-I come up on a left lane camper that could, but is not making significant progress in his "pass", I flash this unit constantly. GTFO of my way you cocksplat!
-I do not "flash to pass" as an alert to me initiating a pass on 2 or 4 lane roads.
