Wash. Admin. Code § 308-100-040 - [Effective 12/23/2023] Examination requirement for commercial driver's license

(1) Persons applying for a commercial driver's license are required to pass a written examination testing their knowledge of commercial motor vehicle laws, rules of the road, and operating characteristics of the class and/or endorsement of vehicles for which they are seeking the commercial driver's license. Applicants are required to successfully demonstrate operating skills for the class of vehicle and endorsement(s) for which they seek the commercial driver's license.
(2) Knowledge and skills test scores are valid according to the following conditions:
(a) Double/triple and HAZMAT knowledge tests are valid for 180 days.
(b) General knowledge, passenger, school bus, air brake, and combination tests are valid for 180 days or through one CLP renewal cycle not to exceed one year (365 days) from the initial issuance.
(c) Tanker knowledge tests are only valid for 180 days unless the endorsement has been added to a valid commercial learner's permit.

When the endorsement is added to the permit, the test scores shall be valid for 180 days or through one CLP renewal cycle not to exceed one year (365 days) from the initial issuance.

(d) Skills tests scores for passed segments of the test are only valid during the initial issuance of the CLP. The renewal of a CLP nullifies any previously passed test segment scores.
(e) Excepting knowledge tests in (a) and (c) of this subsection, knowledge test scores remain valid when a CLP is renewed once for an additional 180 days not to exceed one year (365 days) from the initial issuance. Any subsequent CLP issuance or renewal requires retesting in all relevant knowledge areas.
(3) The department will conduct knowledge and skills examinations that at a minimum meet the requirements of 49 C.F.R. 383.133, as it existed on (effective date of WAC).
