  1. 10 feet

  2. 7 feet

  3. 8 feet, 6 inches

  4. 9 feet

The correct answer is: 8 feet, 6 inches

The maximum width allowed for all vehicles according to Illinois CDL guidelines is 8 feet, 6 inches. This standard width helps to ensure safety on the roads by providing necessary space for vehicles to maneuver, especially in traffic or on narrow roads. It also aids in the regulation of roadway design, including the structure of bridges and roadways, ensuring that vehicles can travel safely without risking accidents due to width limitations. Adhering to this maximum width is crucial for maintaining vehicular control and reducing the potential for accidents caused by oversized vehicles.
