Officially:

LEGAL ROUTES

Where can a 45-foot motorhome be driven? 45-foot motorhomes can legally be driven on the same routes that 45-foot tour buses may currently use. Those routes include all state routes except those on the restrictions list, which is titled "CALIFORNIA STATE HIGHWAY PROHIBITIONS for BUSES & MOTORHOMES over 40 Feet (up to and including 45 Feet)." This list is on the Caltrans web site and can be accessed through this link: Bus & Motorhome Restricted Routes.

Is there a map of bus and motorhome routes? Yes, there is a hard copy map of state routes showing green access routes and red restricted routes for 45-foot buses and motorhomes. Maps are now available -- one copy free per single-unit motorhome over 40 feet. To order, call (916) 654-5741, or e-mail Casey Robb or Manuel Fonseca (see addresses below). When e-mailing, please include complete mailing address and phone number.

Is the map on the Internet? Yes. Please see the web site: http://www.dot.ca.gov/hq/traffops/tr...45-bus-map.htm.

What about city and county roads? AB 67 allowed 45-foot motorhomes primarily on certain state routes, not local roads. Caltrans has jurisdiction over state routes only. Cities and counties have jurisdiction over local roads. To inquire about motorhome access on local roads, contact the appropriate city or county public works department.

What about stopping for services? AB 67 states that a 45-foot motorhome may exit the designated route for fuel, food, and lodging provided the access is safe, and provided the service is within one road mile of an "identified" exit. The exit must be identified to show that the service route has been evaluated and approved. Currently, the only identification system for service exits is a "Service Access" sign, which is an "S" on the back of a truck, as illustrated below. These signs were intended for large trucks, and are located primarily on the Interstates.
