He said you only had to use them when changing directions.....Duhhh!!!
Right, changing directions, not changing lanes. I recall this because I was telling the Michigan Trooper about Troy Michigan cops, weaving thru traffic, putting the public at risk, to do “click it or ticket”. While chasing the drivers down, they were not using their turn signals. The word from the State Police was clear, no turn signal needed (legally speaking) when changing lanes, only direction.
