This bill amends R.S.39:4-77 to require vehicles with large loads or trailers, specifically those whose loads extend above the height of the vehicle's sides or tailgate, to use the right lane of public highways. The bill stipulates that these vehicles may only leave the right lane when necessary to enter or exit the roadway from the left lane. Additionally, it introduces a new section that mandates operators of motor-drawn or towed vehicles to adhere to the same right lane requirement, with violations subject to a fine of up to $500.

The bill also updates the terminology by replacing "director" with "chief administrator" in various provisions related to safety standards for fastening loads on commercial vehicles. It maintains the existing penalty for violations, which is a fine not exceeding $500. The act is set to take effect on the first day of the fourth month following its enactment, although the Chief Administrator of the Motor Vehicle Commission may take necessary administrative actions in advance for implementation.
