Due to the fact that students are generally new drivers who only had their license for a year or less, their car insurance premiums are generally quite high. For this reason, it is usually a good idea to enquire with your insurer if they have a "young driver" offering within their product range to insure student drivers. Similarly, most medical insurance policies will allow children up to the ages of eighteen, sometimes 21, to be listed on the policies as dependents. If these dependents exceed the specified ages, they may still be eligible for "dependent" status on their parents' medical insurance policies if they are enrolled at a tertiary educational institution. Finally, student travel insurance is also widely available. Students can often find cheap medical and travel insurance to cover them while travelling abroad. This is advisable for all students who plan on travelling abroad.
