Before requesting a breath or blood specimen from a person driving a commercial motor vehicle under Tex. Transp. Code §522.102, what must the officer warn the person under §522.103?

  1. That refusal will be admissible at a DWI trial
  2. That refusal will result in the person being immediately placed out of service for 24 hours and disqualified from driving a commercial motor vehicle for at least one year Correct
  3. That refusal will result in a 90-day suspension of the person's personal driver's license
  4. No warning is required for commercial drivers
Why: §522.103(a): an officer requesting a specimen under §522.102 shall warn the person that a refusal will result in the person's being immediately placed out of service for 24 hours and being disqualified from driving a commercial motor vehicle for at least one year under §522.081. The officer is not required to give the Chapter 724 warning (§522.103(b)). Separately, a test showing an alcohol concentration of 0.04 or more while operating a commercial motor vehicle in a public place disqualifies the driver for one year (§522.081(b)(4)(A)). That is a CDL disqualification standard; DWI itself uses the Penal Code §49.01 definition of intoxicated.
Statute: Tex. Transp. Code §522.103; §522.081(b)
