A. A driver shall not refuse to submit to a pre-employment controlled substance test, a post-accident required alcohol or controlled substance test, a random alcohol or controlled substance test, a reasonable suspicion alcohol or controlled substance test, a return-to-duty alcohol or controlled substance test, follow-up alcohol or controlled substance test.

B. The city shall not permit a driver who refuses to submit to such tests to perform or continue to perform safety-sensitive functions. The driver will be immediately removed from duty and such refusal will be treated as a positive test.

C. Failure to provide adequate breath for testing when required without a valid medical explanation, failure to remain available for post-accident testing, failure to provide adequate urine for testing without a valid medical explanation, engaging in conduct that obstructs the testing process, or failure to sign the alcohol testing form constitutes a refusal to submit to testing.
