Multiple recent (2025) and credible sources directly confirm a decline in U.S. heavy and commercial truck sales. Several reports (NADA, Freightwaves, Daimler Truck) explicitly attribute this downturn to 'economic uncertainty,' a 'cooling economic outlook,' and 'pressure on demand,' which aligns with the statement's claim of 'recession concerns.' Source 16 provides a specific figure, stating commercial truck sales were down 6.5% in Q1 2025 due to these factors.
