Although again this varies by location, most rental agencies
don’t charge for spouses or business associates—some include
domestic partners on that list—although some require proof
that the pair lives together. Others don’t charge for additional
drivers if they are members of AAA. Sometimes agencies offer
free additional drivers as a special promotion for short periods
of time or to benefit a partnership with another business.
If you think you would like to use the business associate
claim to get a free driver, remember that you will probably
be asked for proof of this relationship. Some agencies require
a corporate account for your company, while others either
just believe you or ask for business cards from both of
you.
Regardless of whether you will have a spouse, business
associate, or someone else helping you with long distance
driving duties, make sure you know the rules with the agencies
you’re considering as well as the state where you are renting
the car. Some states don’t allow agencies to charge extra
for additional drivers. There is no real proof that adding
a driver adds to the chances of a claim, so even if your
state allows such charges you may be able to find a rental
company that doesn’t charge extra or makes it easier for
you to avoid the charge.
Make sure you know what to expect when you rent a car with
more than one driver. You can even get on the internet and
surf to find the companies that won’t charge you for a second
driver. Check the policies and be prepared.
