(Personalized Letter)
Dear Mr. Doe:
The most recent entry on your driving record places you among a relatively small
percentage of Oregon drivers who have been involved in driving troubles of various
types two or more time during the past twelve months.
It is our hope that this letter will prompt you to review your driving habits and
attitudes and that you will take steps to improve your driving. It also is our
responsibility to inform you that further convictions or accidents may necessitate calling
you to an interview with a Driver Improvement Analyst. Continued difficulty
following the interview may lead to a license suspension.
The need for interview or suspension depends solely upon your future driving
performance, and any new entries on your record will be subjected to careful evaluation
of both the seriousness and frequency of violations and accidents before action is taken.
We believe you are a more capable driver than current records would indicate, and it is
our hope that your true ability to drive will be reflected in an improved performance
during the months ahead. Actually, we believe you will find that it doesn’t require
much effort for a qualified driver to improve to the extent that he can go violation and
accident free year after year. One year of trouble free driving will remove your name
from those receiving special attention. All we ask is your co-operation.
Very truly your,
57
