Senate amends impaired-driving law to close CDL 'masking' loophole and clarify blood-draw rules

The Vermont Senate on May 16, 2025, moved to propose to the House committee-recommended amendments to H.44, a bill with multiple changes to impaired-driving statutes intended to close reporting loopholes affecting commercial driver license (CDL) holders and to update procedures for warrant-based blood draws.

Senate Judiciary Committee reporter Senator Joe Norris (Senator from Franklin District) said the strike-all amendment includes technical corrections, ensures the Department of Motor Vehicles receives adjudication and probable-cause affidavits, prevents "masking" of CDL convictions in compliance with federal rules, and adds a provision governing evidentiary blood samples obtained by warrant while guarding against unintended implied-consent prosecutions.

Norris told senators the federal Commercial Driver License system and federal regulations require states to report certain convictions promptly; "masking" occurs when courts allow convictions to be deferred, dismissed or reclassified in a way that prevents the DMV from learning about convictions, undermining federal reporting requirements. The committee added language to require reporting that prevents masking.

The bill adds a new subsection mandating compliance with the collection of an evidentiary blood sample when obtained through a warrant and amends the implied-consent statutes to inform suspects that they may face a criminal refusal charge for hindering a warrant-based blood collection. The Senate Judiciary Committee further amended the house language by adding the phrase "knowingly hinders" so that a criminal refusal charge requires that the suspect be aware their actions could hinder blood collection; the change was made to avoid prosecuting persons who are incapacitated.

H.44 also creates an impaired-driving processing task force charged with studying implied consent and the processing of DUI investigations, with the goal of reducing law-enforcement hold times and paperwork burdens; the task force must report proposed legislation to the House and Senate Judiciary Committees by Nov. 15, 2025. The committee recommended an effective date of July 1.

Senators asked about practical effects. The senator identified as "Senator from Windsor" asked whether the bill would increase or decrease the number of CDL license revocations; the presenter said the bill's purpose is to stop masking and noted it is not intended to broadly remove CDLs. The discussion included concerns about workforce impacts and volunteer drivers, raised by a senator identified as "Senator from Madison," who said fewer available CDL drivers could strain services such as medical transport.

The Senate Judiciary Committee reported a unanimous 5-0-0 vote in favor of its recommendation, and the Senate voted by voice to propose the committee’s amendments to the House and ordered third reading of H.44.

Next steps: The Senate’s proposed amendments go to the House for concurrence and the task force will begin work under the schedule in the bill.
