Simple: because driving without car insurance is illegal. But there is more to this. Car insurance protects you, financially, if something bad happens. While car insurance can be one of the most costly parts of owning a car - it is also one of the most important! But be aware - not all car insurance is the same. Depending on your coverage, you may or may not be protected from the different problems that may arise. Unfortunately, many people don’t fully understand what their car insurance pays for until they are stuck with thousands of dollars of uncovered expenses.
