Questions people ask
Can I extend my rental car?
Usually, but you must tell the company before the return time. The rate can change when you extend.
What do I do if my rental car breaks down?
Get safe first, then call the roadside number on your rental agreement. Tell us and we'll help you with the next steps.
How are tolls charged on a rental car?
Most companies charge the toll plus a fee for each day you use a toll road. See our toll fees page for each company.
