Vehicle combinations: motorsports: length.

Existing law prohibits a combination of vehicles coupled together, including attachments, from being operated on the highway if a specified maximum length is exceeded, subject to specified exceptions. Existing law permits the use of a semitrailer in exclusive combination with a truck tractor if its length does not exceed 53 feet, as specified. Existing law authorizes the Department of Transportation or local authorities, with regard to highways under their respective jurisdictions, to issue a special permit authorizing a person to operate a combination of vehicles consisting of a truck tractor semitrailer combination with a kingpin to rearmost axle measurement limit of not more than 46 feet on trailers used exclusively or primarily in connection with motorsports, as defined. This bill would authorize the department or local authorities to issue a permit authorizing the operation of a semitrailer used exclusively or primarily for motorsports that is not more than 56 feet in length.
