A tow bar can be installed after purchasing a vehicle and are typically available from automotive supply stores, such as PepBoys. Tow bars can also be purchased from online merchants, such as Amazon.com, and auction sites such as eBay.
Tow bars are typically used to tow a small trailer when camping or moving. Tow bars are designed to fit specific makes and models of cars. Hitches are typically applied to the tow bar to allow the trailer to attach safely. The towing capacity for a vehicle is commonly listed in the owner's manual, and damage can result if the tow bar is applied incorrectly or the weight being towed is too much for the car.
