Different flashes can mean different things: quickly flashing your lights to a truck driver can let them know that their trailer has passed your car with ample space to transfer into your lane and simply that you see them coming. 

It is equally as important to understand how other drivers, and specifically truck drivers, are communicating with you as it is to learn how to “speak” to them. In this article, we will learn how to understand and talk to other drivers using the language of lights.
