Factory orders fell 4% in March, the biggest drop since August, the Commerce Department reported Friday.
The decrease followed a revised 1.9% gain in February that was smaller than originally reported.
The drop was larger than economists’ forecasts of a 2.9% decline, Bloomberg News reported.
Durable goods orders fell 5.8%, the biggest decline in seven months, Bloomberg said.
Orders for capital goods excluding aircraft and military equipment, a measure of future business investment, rose 0.9% following a 4.8% drop the previous month.
Commercial aircraft orders, which tend to be volatile, dropped 48.3%.
The trucking industry relies on factory orders and shipments for much of its business.
