Letter continues:
Furthermore, there is an area surrounding your car known as a "Blind Spot" so named because if there is a car in this area, you will not be able to see it without turning your head and looking directly at it. It's where the term, "check your blind spot" comes from. So please, check your blind spot when changing lanes, and use your turn signal, you will find that with the use of both of these tools there will be sufficiently less near misses and accidents that are your fault.

Thank you!
Kelly.
