Define Technical or Confusing Terms Within the Policy

A set of definitions should be supplied that explain unfamiliar fleet terminology, such as the difference in weight classes between vehicles (light-duty, medium-duty, etc.) and the common vehicle emission categories (ULEV, ZEV, etc.). Note that it is not necessary to write a policy that contains a lot of technical jargon. Indeed, the policy will be more easily understood by all if jargon is kept to a minimum.

This step will not be necessary for many cities or counties.
