724.012(b)(3): At the time of the arrest, the officer possesses or receives reliable information from a credible source that the person: (A) has been previously convicted of . . .

Does the language "at the time of the arrest" mean that for a mandatory draw, the officer needed to know about the previous conviction(s) before they handcuffed the suspect or is it enough that they know before they compelled the sample? I could argue it either way, but absent a definitive answer, I am asking our officers to have dispatch run a history anytime they start SFST. Any thoughts on the issue?

The information can be developed at any time around the arrest but before the mandatory blood draw. Legislators understood that the collection of such information was a fluid event, beginning upon the officer's suspicion that a DWI was afoot and concluding with the mandatory blood draw. Testimony before the committees fleshed out this process.

Don't over-think this thing.

Post arrest determinations by other officers have been allowed under the previous law. Although the issue was source and not timing I agree with John that this is a non-issue. See Mitchell v. State 821 SW2d 420
