Occasionally when you’re driving, you’ll make a mistake and perhaps need to adjust and it can create some awkward situations. Like today, my dad ended up in the wrong lane to go straight instead of turn at a light. He had to cut in line to make sure we could go the right way. It’d be nice if we could communicate “sorry, I screwed up. Excuse me. I just need to slip in there.”
Right now all we have for inter car communication is the horn, which has kind of an aggressive implication to it. This is for trying to de-escalate potential road rage.
You need 2 seconds between every vehicle, and to be able to fully see the vehicle in front of you. When changing lane, you need to fully see the vehicle in your side mirror, center mirror if it’s a truck.
Come on people, that’s all in the paper exam for your licence.
I believe OP is talking about cutting into a line of stopped vehicles, which is not against the law, but also considered rude (if you had a chance to cut in earlier but you didn’t)
