The Rolling Road Block

a rolling road block is when multiple police cars drive side by side blocking all lanes of traffic. they do this for various reason. most often i hear about it being used to stop a suspect in i high speed pursuit, but i have also heard about it being used by construction crews during various maintenance operations on a highway.

yesterday morning while driving southbound on 35E on my way to work i came upon a rolling road block created by two tractor trailers and one box truck. this is an event that i run across more often then i would like to. i can't help but wonder if they are aware of the fact that they are hindering the flow of traffic. yesterday while the pile of cars behind the rolling road block grew i started to wonder if maybe they do this for fun sometimes. i think they all get on the cb radio and plan it. i don't believe this was the case yesterday since it was caused by two tractor trailers and a delivery truck, but i can't help but wonder about other times. basically this unnecessary road block bothers me. am i the only one to notice this out there?
