North American medium and heavy-duty truck volumes rose incrementally in June compared to May's three-year low, though they remained down 69% from June 2018. Preliminary data showed 13,100 Class 8 trucks were ordered in June, up 20% from May but a significant drop from the previous year. The medium-duty order trend also remains below 2018's pace due to underlying consumer economic strength, with June orders for Classes 5-7 trucks at 19,200 units, down 30% year-over-year.
