Towing a Trailer Additional Towing Equipment Many states and Canadian provinces/territories require special outside mirrors when towing a trailer. Even if they don't, you should install special mirrors if you cannot clearly see behind you, or if the trailer creates a blind spot. Ask your trailer sales or rental agency if any other items are recommended or required for your towing situation. Pre-Tow Checklist When preparing to tow, and before driving away, be sure to check the following: The vehicle has been properly serviced, and the suspension and the cooling system are in good operating condition. The trailer has been properly serviced and is in good condition. All weights and loads are within limits. The hitch, safety chains, and any other attachments are secure. All items in or on the trailer are properly secured and cannot shift while you drive. The lights and brakes on your vehicle and the trailer are working properly. Your vehicle tires and spare are properly inflated, and the trailer tires and spare are inflated as recommended by the trailer maker. 440
