Washington State law requires auto repair facilities to post customer rights.

Customer rights include:

• Written estimates – Generally, estimates that exceed $100 must be in writing and must identify the repair facility, the auto owner and the auto.
• Unauthorized charges – A repair facility may not charge the customer more than 110% (excluding sales tax) of the total shown on the estimate unless oral or written authorization is given by the customer before the work is started.
• Repair invoices – In addition to the estimate information, parts and labor must be clearly and accurately recorded in writing on an invoice.
• Disposition of replaced parts – The repair facility must return replaced parts to the customer at the time the work is completed if the customer requested them. This does not include parts covered by a warranty or parts that must be returned to a distributor, remanufacturer, or rebuilder (which only need to be shown to the customer),
• Unlawful acts or practices – Auto repair facilities must not practice:

-	False advertising
-	materially understating or overstating an estimate
-	taking payment from a customer for parts or labor not delivered
-	unauthorized operation of a customer's vehicle
-	failing to give a customer, upon request, any document signed by the customer
-	taking duplicate payments from both the customer and the warranty provider
-	charging for unnecessary repairs

Posted signs must be printed in letters no less than one and one-half inches high. The Department of Revenue has provided signs to most auto repair facilities. New auto repair facilities are provided signs as part of their tax registration materials.

For additional signs, call the Department of Revenue at 1-800-647-7706.
