You’re driving behind someone who suddenly slams on the brakes and makes a quick right turn — without signaling. You narrowly avoid hitting them. Minutes later, you forget to signal before switching lanes and think, “It’s no big deal, people should be paying attention.”

Should you feel responsible for signaling, even if others don’t?

You’re in the far right lane and see an opening to turn left into a parking lot across two lanes of traffic. It would mean cutting across without warning and technically breaking traffic laws. You're in a hurry, and making the legal left turn would take 5 extra minutes. 

Is it okay to break the rules if it saves time and “no one gets hurt”? 

You're in a school zone. A driver leaves their blinker on, you tailgate out of frustration. You've done the same in the past. 

What’s the ethical responsibility in school zones and when signaling?
