MOTORSPORTS EXEMPTION

An otherwise legal truck tractor-semitrailer combination vehicle traveling to or from a qualifying motorsports venue may have a KPRA length of up to 46 feet if operating on the designated STAA Network and Caltrans-approved motorsports access routes. (Complete text of Vehicle Code exception shown below)
LEGAL DIMENSIONS

Height & Width: Vehicle basic height law in California is 14 feet. The basic width law is 102 inches.

Length: Vehicles qualifying for the motorsports KPRA exemption must comply with all other length requirements. Basic length laws in California are as follows:

California Legal

STAA Truck with 48' Trailer

STAA Truck with 53' Trailer

Semi-trailer = no limit
KPRA = 40' max (if 2+ axles)
KPRA = 38' max (if 1-axle)
Combination length = 65' max

Semi-trailer = 48' max
KPRA = no limit
Combination length = no limit
Semi-trailer = over 48', but 53' max
KPRA = 40' max
Combination length = no limit

Access: virtually anywhere in California.

Access: STAA Network only!

Access: STAA Network only!

POWER UNITS

Truck Tractor: To qualify for the motorsports exemption, the power unit must meet the definition of a "truck tractor" per the California Vehicle Code (CVC) (with bolding added):

655. (a) "A 'truck tractor' is a motor vehicle designed and used primarily for drawing other vehicles and not so constructed as to carry a load, other than a part of the weight of the vehicle and the load so drawn. As used in this section, "load" does not include items carried on the truck tractor in conjunction with the operation of the vehicle if the load carrying space for these items does not exceed 34 square feet."

Dromedaries: As stated in the definition above, "droms" may carry only items required for the operation of the vehicle. If the "droms" carry other items, the vehicle converts to a California Legal combination with a maximum allowed overall length of 65 feet.

Buses & Motorhomes: A bus or motorhome is not considered a truck tractor. If it is used as a power unit, it would not qualify for the motorsports exemption. However, a bus or motorhome can certainly travel to motorsports events if it is a legal vehicle on the required routes. The legal length of a single-unit vehicle in California is 40'. A bus or motorhome may exceed 40' up to a maximum of 45', provided that they stay on designated routes. The routes for the over-40' buses and motorhomes are not related to motorsports routes. When a bus or motorhome tows another vehicle, the combination cannot exceed 65' in length. (Return to the Office of Truck Services web page and scroll to the topic "6 - 45' Buses & Motorhomes" for a map of designated routes, and links to two web pages entitled "45' Buses" and "45' Motorhomes.")
OPERATIONAL REQUIREMENTS

Commercial vehicles are subject to all motor carrier regulations. Many of these requirements are listed and summarized on the Office of Truck Services web page under the heading "Commercial Vehicle Operations Guide."
MOTORSPORTS EVENTS

Motorsports definition: In the context of this law, a motorsports event is any event sanctioned under the auspices of the member organizations of the Automobile Competition Committee for the United States. Those events are listed in the table below.

Exemption of event activities: This exemption also applies to all activities leading up to that event, including, but not limited to, administration, testing, practice, promotion, and merchandising.

Events outside California: Vehicles registered in California and participating in a motorsports event outside of the state may use the STAA Network (National Network, Terminal Access routes, and Service routes) within California.
APPROVED ROUTES

The law mentions issuing of permits. However, in lieu of issuing permits, the Department of Transportation (Caltrans) worked with local authorities to develop the following list of approved routes for each motorsports venue. Note that some routes allow only California Legal vehicles, and one allows only STAA vehicles. (See abbreviations at end of page.)

State Legislation: California Senate Bill 1463 codified the federal motorsports KPRA exemption in California law. The governor signed the bill August 17, 1996 and it became law January 1, 1997.

California Vehicle Code: The motorsports exemption is located in the California Vehicle Code (CVC), Section 35401.5 and is copied here in part (bolding added):

As used in this paragraph, "motorsports" means any event, and all activities leading up to that event, including, but not limited to, administration, testing, practice, promotion, and merchandising, that is sanctioned under the auspices of the member organizations of the Automobile Competition Committee for the United States."

Subdivision (a): A combination of vehicles consisting of a truck tractor and semitrailer ... is not subject to the limitations of Sections 35400 and 35401, when operating on the National System of Interstate and Defense Highways ... or when using routes appropriately identified by the Department of Transportation or local authorities ... if all of the following conditions are met: (1) The length of the semitrailer ... does not exceed 48 feet. A semitrailer not more than 53 feet in length shall satisfy this requirement when configured with two or more rear axles, the rearmost of which is located 40 feet or less from the kingpin or when configured with a single axle which is located 38 feet or less from the kingpin. ...
