I love the old book!We have right turn on red too. Another thing I'm careful about is when the signal light turns green...if I'm in the lead, I look to make sure that those who are supposed to stop actually stop. Be sure to stress that to your son. BFF got broad-sided. No one was hurt, but because the broad-sider had a crying child in the back seat, she was not ticketed!
What a great find!!!
