case more than 8 hours after the accident. Employees must refrain from all alcohol use until the test is complete. Post-accident drug test must be conducted within 32 hours.

  1. Reasonable suspicion. Tests will be conducted when a supervisor or manager observes behavior or appearance that is characteristic of alcohol or drug use. If a driver's behavior or appearance suggests alcohol or drug use, a reasonable suspicion test must be conducted. If a test cannot be administered, the driver must be removed from performing safety-sensitive duties for at least 24 hours. Testing for alcohol abuse must be based upon suspicion, which arises just before, during or just after the time when the employee is performing safety-sensitive duties. Testing for substance abuse may occur at any time upon suspicion. Reasonable suspicion testing may only be conducted after consultation with the Director of Public Works or his/her designee.
  2. Random. Tests will be conducted on a random, unannounced basis just before, during or after performance of safety-sensitive functions for alcohol, or at any time for drugs. Each year, the number of random alcohol test conducted by the Town must equal at least 25% of all the safety-sensitive drivers. Random drug tests conducted by the Town must equal at least 50% of all safety-sensitive drivers.
  3. Return to duty and follow-up. Tests will be conducted when an individual who has violated the prohibited alcohol or drug standards returns to performing safety-sensitive duties. Follow-up tests are unannounced and at least six (6) tests must be conducted in the first twelve (12) months after a driver returns to duty. Follow-up testing may be extended for up to sixty (60) months following the return to duty.

B. Conducting tests

  1. Alcohol. DOT rules require breath testing using evidential breath testing (EBT) devices. Two (2) breath tests are required to determine if a person has a prohibited alcohol concentration. A screening test is conducted first. Any result less than 0.02 alcohol concentration is considered a "negative" test. If the alcohol concentration is 0.02 or greater, a second, confirmation test must be conducted.
