(1) The rules in this chapter apply to passenger transportation companies subject to the jurisdiction of the commission under chapter 81.04, 81.68, or 81.70 RCW. The rules apply to all passenger transportation companies, unless a part, rule, or reference within a rule states otherwise. These rules also include various requirements that apply to the companies' customers and to companies applying for certificates.

(2) The tariffs filed by auto transportation companies must conform to these rules. If the commission accepts a tariff or schedule that conflicts with these rules, the acceptance does not constitute a waiver of these rules unless the commission specifically approves the variation consistent with WAC 480-30-046. Tariffs that conflict with these rules and are not specifically approved by the commission are superseded by these rules.

(3) Any affected person may ask the commission to review the interpretation of these rules by filing an informal complaint under WAC 480-07-910 or by filing a formal complaint under WAC 480-07-370.

(4) No deviation from these rules will be permitted without written authorization by the commission. Violation will be subject to penalties as provided by law.
