I offer you a challenge! I have thought for many years that we need a universal standardized set of hand signals—for good,or informative, messages to fellow drivers. It would be so helpful if someone—and why not you—could come up with signs for the following situations or expressions:
Go ahead, I yield. (This one I use by extending palm up and directed to person I am addressing.)
Your turn signal is still blinking.
You have a very low tire.
You have other car problems.
That's just the beginning—you can probably think of more. Or maybe your listeners can help?
Please accept my challenge to you for the safety and well being of all drivers. Thank you.
