Oct. 29, 2025, 5:20 p.m.
New York State’s transportation network is one of the busiest and most complex in the U.S. To move oversized or overweight (OS/OW) loads safely across its highways and bridges, trucking companies must obtain specific permits regulated by the New York State Department of Transportation (NYSDOT). These permits ensure safety, compliance, and protection of infrastructure while supporting vital industries such as construction, manufacturing, and energy.
