Travel insurance is short-term insurance available specifically against travel-related emergencies and expenses. International travellers will almost always want to obtain travel insurance because it covers medical expenses, but even other travellers may find it useful depending on their plans.
This article describes common items covered by travel insurance policies and what to check for on your policy. With any policy, it is important that you read the terms and conditions carefully and that you especially review the exclusions (things that the policy definitely does not cover).
This article is a general guide to travel insurance policies, including some possible terms but is not a substitute for careful review of your own policy. Travel insurance policies differ markedly in their terms and conditions.
