What is the maximum allowable width for most vehicles in Illinois?

In Illinois, the maximum permissible width for most vehicles is 8 feet. This standard is established to ensure safe travel on state roadways, facilitate the passage of vehicles, and minimize the risk of accidents due to width restrictions. Vehicles exceeding this width require special permits, as wider vehicles can pose challenges in navigating through narrow streets, bridges, and when passing other vehicles. Understanding this regulation is crucial for drivers and operators of commercial vehicles to remain compliant with state laws and ensure a safe driving environment.
