Anyone checked clearance with a rangefinder?

That little round mirror works well on your truck, but it's worthless if you've got an oversize, wide and tall load on your trailer... like I often do... lol

 

Wherever I go, if there are people behind me and I'm driving at the speed limit or below, you can bet that they are working hard at finding a way around me. They work even harder at it when I'm stopped in the middle of the road. If there's a clear path around me, you can bet that there are no cars behind my stopped truck.

I don't allow that. I always park in such a manner that I cannot be blocked by anyone else. If someone blocks me, then it would have to have been a deliberate act that could not have been prevented. Always think ahead.

Would be interesting to see how accurate they are. I was driving in upstate New York today, and I saw a NYDOT truck under an overpass, and the employee was measuring the clearance at the fog line with a measuring stick. I'd think that if the range finders were anywhere near close to being accurate that they'd be using one instead. Much less work.
