When turning right on red, be sure to look for traffic to your left and look for the oncoming traffic turning left in front of you. If you fail to look for the traffic turning left into the lane you have already started turning on and you get honked at, don't give the driver who has the right-of-way the innocent, "What did I do?" look. You're still wrong. You violated the rules of the road. When driver of the car honks at you and you hear screeching tires, be aware that the person who is about to hit the driver you are cutting off is not at fault, but you are. If you hear crunching metal, stick around like a good citizen and take your punishment for causing an accident.
Luckily I didn't get hit today, but it was thisclose to being an accident.
I wish I could say it was a teenager or a person on their cell phone or even a distracted mom trying to clam a 2 year old down from a temper tantrum while throwing cheerios at the 4 year old. It wasn't. It was a middle aged lady who was just plain clueless.
