Yes, boats and trailers can be towed on The Toll Roads. If paying with an electronic tolling account, the license plate number of the boat or trailer must be listed on your account. You can add the plate online or using our free app. California State Highway laws also apply on The Toll Roads, therefore any vehicle pulling a boat or trailer must follow the same rules and regulations as on the other highways. Please note, boats and trailers cannot be towed in the 91 Express Lanes (Opens in a new window) , the tolled lanes in the median of the 91 Freeway that are owned and operated by the Orange County Transportation Authority and Riverside County Transportation Commission.
