U.S. factory orders fell 4.6% in November, the Commerce Department said Thursday.
The downturn followed a revised 6% decline in October that was more than the 5.1% originally reported.
Economists had forecast a 2.3% decline, Bloomberg reported, and the back-to-back decline was the biggest since records began in 1992.
Durable goods orders, which make up about half of factory orders, fell 1.5%.
The trucking industry relies on factory orders and shipments for much of its business.
