The principles of the traffic insurance price calculation are different for different insurance companies. Every insurance company calculates the price independently on the basis of its own principles. When calculating the traffic insurance premium, insurance companies take into consideration the performance characteristics of the vehicle (its make, model, capacity, weight, etc.) and the aspects connected with its owner (their insurance and accident history, place of residence, etc.) The precise formula for calculating the cost of traffic insurance is kept secret at every insurance company.
