Fleet Rules

Notices and Advisories

Fleet Rule Information

To reduce both toxic and smog-forming air pollutants, the South Coast AQMD adopted seven rules that will gradually shift public agencies and certain private entities to lower emissions and alternative fuel vehicles whenever a fleet operator with 15 or more vehicles replaces or purchases new vehicles. All seven fleet rules are now in effect. Readers should review each rule that would affect their purchasing or contracting procedures involving fleet vehicles. For some entities, more than one rule may apply.
