RCW 70.87.110: Exceptions authorized.

The requirements of this chapter are intended to apply to all conveyances except as modified or waived by the department. They are intended to be modified or waived whenever any requirements are shown to be impracticable, such as involving expense not justified by the protection secured. However, the department shall not allow the modification or waiver unless equivalent or safer construction is secured in other ways. An exception applies only to the installation covered by the application for waiver.
