Recommended for you

These myths fuel avoidable exposure. Understanding the actual coverage—and its limits—empowers smarter decisions behind the wheel.

Premiums typically range from $10–$25 extra, depending on coverage level and rental duration. For many, this fraction safeguards against catastrophic financial loss.
