You can actually save money when you get a multiple car insurance quote. Insurers take into consideration the fact that you can not drive two vehicles at the same time, so they charge less for each additional one. Insuring all of your vehicles with the same company will usually cost less than it would to insure them individually.
Insurance rates are calculated by factoring the cost of replacing a vehicle and the likelihood of you being involved in an accident. Statistical data is compiled from a large quantity of accidents in order to determine who is most likely to be involved. The data is categorized and people are divided into groups according to age and gender.
Other factors are also used to determine insurance rates. Whether you live in the country or in a big city can make a difference. If you live close to an intersection where many accidents are known to occur you could end up paying more. Sometimes your credit history or even the number of miles you drive to work each day are factors.
Actuators are employed or hired by insurance companies to assess risk. Their job is to determine which categories each driver falls under in order to decide how much they need to pay. The goal is to charge the most for the worst drivers and the least amount for the best drivers. Sometimes rates may not seam fair but they are determined by using the results from large pools of data.
