The Act amends the Michigan Vehicle Code to allow a truck tractor and lowboy semitrailer combination of any length to operate on a designated highway, subject to certain conditions.

The Code prescribes maximum lengths for different types of vehicles operating on designated highways (highways approved by the Michigan Department of Transportation (MDOT) or a local authority with respect to highways under its jurisdiction).

The bill provides that, for a truck tractor and lowboy semitrailer combination on a designated highway, there would be no maximum length, if the lowboy semitrailer did not exceed 59 feet, except as otherwise permitted. A lowboy semitrailer wheelbase could not exceed 55 feet as measured from the kingpin coupling to the center of the rear axle. A lowboy semitrailer longer than 59 feet could not operate with more than any combination of four axles unless an oversized load permit were issued by MDOT or a local authority with respect to highways under its jurisdiction.

Sec. 3 (a) removes the restriction of no more than 3 axles on trailers longer than 50 feet, but does not change the requirement for a king pin to rear axle/tandem setting of 37- 41 feet. "Lowboy semitrailer" would mean a flatbed semitrailer with a depressed section that has the specific purpose of being lowered and raised for loading and unloading.
