“....creating a rolling roadblock so nobody gets around them.”
I’ve encountered that BS from time to time from 18-wheelers and easily remedied that by going around them at an on ramp. Prolly illegal but so is intentionally impeding traffic with a rolling roadblock.
It’s great when one 18-wheeler decides to pass another 18-wheeler on a long uphill.
Gotta wonder why they even bother.
18-wheelers do that thing where they are on cruise control and want to pass another truck so they do it without speeding up, which can amount to a 10 or 15-mile roadblock because of their 1 or 2-mile difference in speed.
