FreightWaves Highlights Insight from Benesch’s Brian Cullen on California’s Diesel TRU Emissions Regulations

April 14, 2026

Brian Cullen, of counsel in Benesch’s Transportation & Logistics Practice Group, was recently quoted in the FreightWaves article, “California regulators have started a regulatory push on diesel TRU emissions.” The article examines the California Air Resources Board’s (CARB) latest efforts to tighten regulations on diesel-powered transport refrigeration units (TRUs), highlighting the impact on carriers, shippers and equipment manufacturers operating in the state.

But the TRU rules are still intact. “The state is trying to figure out a way to still regulate the industry a bit,” Cullen said. “So that’s one part. And then two, it seems like they have all these CARB employees who were in charge of other items, needing something to do or needing to work.”

The article details the regulatory changes, the timeline for compliance and the potential challenges facing industry stakeholders as California continues to lead the way in emissions regulation. Cullen’s comments underscore the importance of proactive planning and staying informed as the regulatory environment continues to shift.
