As in other countries, the third party liability insurance is compulsory in Spain for all vehicles in circulation and even those which are simply parked on public streets or roads. A Spanish insurance is only available if the car is registered in Spain.
In Spain the premium is very high for drivers below the age of 25 years. This is obviously a reflection of the large number of accidents young people cause. Some insurance companies even refuse to insure young drivers. Others require that additional insurances are taken out.
