This is a Turn Signal Switch

THIS IS A TURN SIGNAL SWITCH

(In Boston it's a "blinkah")

This seems to me to be extremely fundamental! But I think it's worth mentioning and explaining what it is, what it does and how it effects you and other drivers.

What it is:

 - it is a universal switch lever located in the same place on virtually EVERY motor vehicle, generally behind the steering wheel on the left side.

What it does:

 - when you press down on it, it turns on the left turn signal.

 - when you lift it, it turns on the right turn signal.

 - when either action is performed a light turns on in the front and in the rear of the vehicle which blinks.

Effects on the road:

 - when used properly, this lets other drivers on the road know what you intend to do.

 - when used properly, you become predictable and avoidable (and you don't want to be Mr. UNpredictble on the road).

When to use it:

 - changing lanes on a highway.

 - when your lane ends and you have to merge right or left.

 - when you are making a right or left hand turn.

 - when in a parking lot and turning into your chosen spot

I know this sounds fundamental, but it is absolutely ridiculous how many drivers think they're either too cool or are just plain lazy! PLEASE...use your "blinkah!!!"
