(a)  Alcohol screening test devices that measure alcohol concentration through testing the breath of individuals are approved on the basis of results of evaluations by the Forensic Tests for Alcohol Branch. Devices shall meet the minimum requirements as set forth in the Department specifications for Alcohol Screening Test Devices. Evaluations are not limited in scope and may include any factors deemed appropriate to insure the accuracy, reliability, stability, cost, and ease of operation and durability of the device being evaluated. On the basis of evaluations to date, approved devices are listed in 10A NCAC 41B .0503 of this Section.

(b)  When the validity of an alcohol screening test of the breath of a driver administered by a law enforcement officer depends upon approval by the Department of the test device and its manner of use, the test shall be administered as follows:

(1)           The officer shall determine that the driver has removed all food, drink, tobacco products, chewing gum and other substances and objects from his mouth. Dental devices or oral jewelry need not be removed.

(2)           Unless the driver volunteers the information that he has consumed an alcoholic beverage within the previous 15 minutes, the officer shall administer a screening test as soon as feasible. If a test made without observing a waiting period results in an alcohol concentration reading of 0.08 or more, the officer shall wait five minutes and administer an additional test. If the results of the additional test show an alcohol concentration reading more than 0.02 under the first reading, the officer shall disregard the first reading.

(3)           The officer may request that the driver submit to one or more additional screening tests.

(4)           In administering any screening test, the officer shall use an alcohol screening test device approved under 10A NCAC 41B .0503 of this Section in accordance with the operational instructions supplied by the Forensic Tests for Alcohol Branch and listed on the device.
