Trucking demand refers to the amount of goods and products that need to be transported by trucks. It is determined by a variety of factors, including the overall state of the economy, the level of consumer spending, and the level of industrial production. When the economy is strong and consumer spending is high, trucking demand tends to be high as well, as more goods need to be transported to meet the needs of consumers. Conversely, when the economy is weak and consumer spending is low, trucking demand tends to be low as well, as fewer goods need to be transported. Additionally, when industries are producing more goods, it will drive trucking demand.
