6 Potential Errors on the ATF
Te ATF records test results from an alcohol testing device. It is important that the four steps required by the ATF are completed correctly. Failure to do so or to recognize and correct errors aſter a test may invalidate it. Step 1 of ATF completion is straightfor-
ward: Complete the subject’s information, the DER’s contact info and the reason for the test. Tis can be completed before the test. Te most common errors in ATF
completion arise in steps two, three and four of the ATF: ATF Step 2: Neglecting to have the test
subject sign and date this section on the ATF before conducting the screening test. In Step2, the subject signs the form to confirm they a) received the test instruc-
tions printed on the back of the ATF, b) had the opportunity to read the instruc- tions if they so chose, and c) consented to the screening test. Logically, this must be done before submiting to the test. ATF Step 3: Prematurely checking the
15-minute wait box and/or checking this box when only a screening test has been performed. Do not check this box unless it is time to do so. ATF Step 4: Having the subject sign
the ATF in Step 4 when they don’t need to. When the subject signs the ATF, they are agreeing not to drive or perform any safety sensitive duties. Subject signature is only required aſter the subject has had a positive confirmation test. It is both unnec- essary and incorrect for the subject to sign the ATF aſter a negative confirmation test.
Correctly completing the Alcohol Test Form is critical to proper Evidential Breath Testing
