Definition of Open Carrier - This is Car Shipping that does not protect your vehicle from the elements.
Shipping your vehicle on a open carrier does expose it to the weather, but the Auto Transport companies can fit more vehicles on their truck and this lowers the cost of Vehicle Shipper. Damages from the elements are rare, but can occur. Most people are willing to take the small risk to save a considerable amount of money.
