The trucking industry has been undergoing a significant transformation in recent months, with two federal agencies playing a crucial role in reshaping the driver pool. The Department of Transportation (DOT) and the Department of Homeland Security (DHS) have operated in close coordination, tightening who can legally hold a Commercial Driver's License (CDL) and pulling drivers off interstates and out of their homes who could no longer pass that standard. This two-agency enforcement operation has been one of the primary supply-side stories in trucking since mid-2025, with significant implications for small carriers and owner-operators.
The impact of this enforcement wave can be seen in various statistics. FMCSA removed over 7,000 CDL schools from its Training Provider Registry, cutting off the pipeline that was creating fraudulent new CDL entrants. The March 16 Final Rule on non-domiciled CDLs has now taken legal effect, eliminating eligibility for the large majority of current holders who do not meet the new visa standard. California revoked 17,000 CDLs in a single enforcement action, and New York faces DOT orders to revoke more than half of its 32,000 non-domiciled CDLs.
The structural direction has not changed, but the management quality and political stability of the agency executing it may improve with Mark Mullin's arrival. As a hardline immigration enforcer from Oklahoma, Mullin is well-positioned to maintain and potentially escalate the posture established by Kristi Noem. He represents a state that pioneered this enforcement model and has personal and political roots in the most aggressive state-level enforcement partnerships in the country.
Mullin's background and stated positions suggest he will continue to prioritize immigration enforcement, which may lead to more drivers being pulled off the road. The practical concern raised by some analysts is that Stephen Miller, the White House Deputy Chief of Staff, will continue to drive immigration policy from inside the White House, potentially overriding Mullin's priorities.
The supply-side market story has not yet fully materialized in spot rates, with demand remaining soft and enforcement implementation slower than anticipated. However, the cumulative pipeline of capacity removal is building, with estimates suggesting that up to 614,000 drivers could exit the commercial driving market if the full scope of immigration enforcement and CDL restriction runs its course.
The J.B. Hunt study by Noël Perry of Transport Futures estimated that a recession would dampen the rate impact, but a multi-year enforcement maturation is still expected. FTR's Avery Vise has projected a potential 'market that is like 2021' by year-end 2026 if enforcement matures and demand stabilizes.
The DHS leadership change is not a pivot point for small carriers and owner-operators, but rather a continuity signal with an asterisk for the shutdown resolution wildcard. The person at the top of DHS changes, but the enforcement architecture underneath that person remains largely intact.
Mullin's arrival may create a temporary opening for a funding resolution that Noem's presence was obstructing. If that happens, it would restore full DHS operational capacity, including ICE's enforcement budget and staffing, which would likely mean more enforcement activity, not less.
The transition from Kristi Noem to Mark Mullin at DHS is unlikely to change the direction of enforcement, but may bring more operational stability. As a hardline immigration enforcer with personal and political roots in the most aggressive state-level enforcement partnerships in the country, Mullin is well-positioned to maintain and potentially escalate the posture established by Noem.
