I don’t know if it’s just some of my local officers and troopers but I very commonly will see LE vehicle just changed lanes without using any signal. It’s not even when they are going lights and sirens to a call it’s when they’re driving normal speed just changing lanes. That’s not to say they can’t be going to a call with no lights and siren more that it’s a little weird to watch somebody cross four lanes of traffic and not use their signal once. Or just not put on a turn signal when they’re turning out a light.
Maybe there’s a reason for it but I always found it weird how some do and a lot don’t. Are there any practical reasons I’m missing for why they wouldn’t use a turn signal when just driving in traffic or at a light?
