I've been traveling quite a bit this summer. In a three day period last week I drove more than 1900 miles. Just yesterday I headed south from Dayton, Ohio to Tuscaloosa, Alabama. One constant that I see is that very few (VERY FEW) drivers signal their intent to change lanes.
I know that when I was taught to drive the instructor would say, "if you're going into a different lane than you are now driving, you MUST signal first. If you are turning from one street to another, you MUST signal first. If you are pulling to the side of the road, you MUST signal first." I guess you get the point.

In Conversation
This makes me wonder how often we don't signal our intent during conversation. How often have you been talking with someone and you find that the topic has taken a sudden turn? Did you know this was happening? Or are you in a moment of complete disconnect, because you are still thinking of responses from the previous train of thought? Do you sometimes find yourself clarifying their last statement because you haven't a clue about what they are now saying? How often does this lead to argument at home -- for no apparent reason than two people have gone two completely different directions. You don't necessarily disagree with each other; you simply don't know what the other person is saying. You weren't told the conversation was going elsewhere.
In Presentation
This same dilemma can affect the comprehension of your content when you are presenting a class, workshop, or even a proposal. If you haven't told your listeners that you are going to switch lanes -- or that you are taking a sidebar -- or that you have moved beyond the last topic of learning, they will likely become confused. Is your key message going to be lost because they don't know how to connect it to the thread that they thought was still taking place?
Give Fair Warning
In most cases, when we signal our intent we are warning the people around us that the environment is changing. It gives them a chance to slow down, to look around, or to clear their mind to prepare for the change. When the people on the road have switched lanes without warning, others become angry, get confused or even create dangerous situations that could result in tragedy.
If you are moving another direction, do the right thing. Signal your intent.
