The big truck is a dominant feature in our modern society. Alexander Winston sold his first horseless semi-truck 1899 and in 1913 Maine was the first state to limit the wight of trucks on its roads, to 18,000 pounds and that becane a norm. There are abt 4.06 million semi-trucks operating in the USA. The payload is abt 42,000 and 48,000 on the usual semi-trailer, meaning the trailer fleet can move abt 170,520 million pounds around. Add to this all the special big trucks. 8.4 million people are employed in the trucking industry, 3.54 million are truck drivers, excluding the self-employed (2022). Follow the big trucks and their loads in pictures and short comments. We honor this great industry on 4th of July and Labor Day and hope you will enjoy our selection of photos.
