The U.S. used truck and trailer market continued to tighten in August, with inventories declining across heavy-duty and medium-duty trucks and remaining well below year-ago levels. Used semi-trailer inventory was the exception on a monthly basis, edging up 0.7%, though it remained down more than 31% year over year. Pricing trends were mixed: asking values generally increased month over month, while auction values strengthened across most categories. Heavy-duty truck auction values rose both monthly and annually, while semi-trailer values posted particularly strong year-over-year gains. Medium-duty trucks continued to show softer year-over-year pricing despite modest monthly increases.
