DOT Breath Alcohol Technician (BAT) Course Practice Test

Which record type has a retention period of 5 years?

Records of DOT alcohol tests resulting in 0.020 or greater Negative test results Cancelled tests Training records

Correct Answer:

Records of DOT alcohol tests resulting in 0.020 or greater

Explanation:

Record-keeping timelines for DOT alcohol testing are set so that more serious or potentially contentious results stay on file longer. The category that has a five-year retention is the set of records showing an alcohol test result at or above the 0.020 level. Keeping these results for five years creates a reliable audit trail in case of investigations, disputes, or regulatory reviews over time. Other records—like results that show no detectable or very low alcohol, tests that were cancelled, and training records—aren’t kept for five years. They serve different purposes (verifying a test occurred, showing the test was invalid, or proving training completion) and are retained for shorter periods appropriate to those functions.
