federal legislation is in the process to regulate trucking regulations

When a passenger aircraft leaves from any U.S. airport it is subject to following all federal regulations. However, for a truck driver the laws are determined by each state it is driving through. Nevertheless, federal legislation is underway that would limit state regulations unless approved federally. There are different arguments to this new act. For example, the Owner Operator Independent Drivers Association believes that this would favor influential industry interests. While the Western States Trucking Association believes that it would cause confusion to employers and increase lawsuits. They also believe that it would affect the safety negatively.
​
The U.S. constitution permits the administration of interstate travel and commerce by the federal government, but states continue to have power over the monitoring of transportation within their boundaries. If this legislation were to pass it would create a simpler process overall for the industry and in the understanding of regulations. Supporters also state that it would create and allow all companies to comply to industry wide standards easier. They believe that since drivers are passing through multiple state lines a day it confuses them adapting to each state's laws. This regulation would also include the increase of weight limits for trucks. Learn more about the plans for this legislations and the various arguments on trucks.com
