How to Use Your Turn Signal
Part of safe driving is letting the other drivers around you predict what you will do. Using your turn signals is not difficult, and it's generally required by law whenever you make a turn or change lanes. Providing a signal to turn to other drivers, both in front of you and behind you, is to communicate to them, your intentions to change lane or directions. Communications is a effective tool to help prevent most accidents from happening.
1) Locate the lever on the left side of the steering column. (This lever will be on the right in any car designed for driving on the left side of the road.)

2) To signal a left turn, push the lever down (or up if the lever is to the right of your steering column).

3) To signal a right turn, push the lever up (or down if the lever is to the right of your steering column).

4) Once you have moved the lever up or down, an arrow light will begin blinking on the dashboard.

5) The signal will automatically turn off after you have made the turn, in most cases, but you must turn the wheel past a certain point. If it doesn't automatically turn off, move the lever back to its central, neutral position.
Practice using your turn signal in your drive way at home if you have to, it really helps all other drivers out there figure out which direction you're going to turn and can prevent a lot of accidents.
Remember, we're not mind readers, we can't predict which direction you're going to steer your vehicle at any time.
Be smart, take a second to use your turn signals, it's really not that difficult.
