Hire a car? Do you mean rent? You can rent a car at the age of 25. But you can get a U-Haul at 18. =)

In the US you would do best by visiting each major car rental company’s Web site as they all change regarding policies. Here is the information for example, for one major company, AVIS: http://www.avis.com/AvisWeb/JSP/global/en/rentersguide/policies/us/US_Age.jsp Age At participating locations, Avis recently lowered the rental minimum age to 21 years old in all states except: • Locations in the states of Connecticut, Washington DC, Iowa and Idaho, and select locations in New Jersey. Rather than requiring customers to be 25 to rent, Avis now rents to customers between the ages of 21-24 with a valid credit card and driver's license. At time of rental, we will automatically apply an additional $25-per-day underage surcharge for these drivers. New York State will continue to have a minimum age of 18 with a $110 surcharge per day for renters age 18-24. In the United States we do not have a maximum age requirement. Government Minimum Age Policy - Military and Civilian Personnel Military (Fema, US Postal Dept., Navy and Army) and Civilian Personnel • Minimum age - 18 years (No underage surcharge will apply) with Government Travel or Purchase order • Minimum age - 21 years (No underage surcharge will apply) no travel or purchase order Additionally, the following restrictions also will apply for renters between the ages of 21-24: Renters of luxury, Mini-Vans, 12-Passenger Vans, Specialty, and Full-Size SUVs, Premium SUVs will not be permitted. For International rentals, maximum and minimum age policies may apply and vary by country.

Besides not wanting to rent a car to young drivers, many rental agencies think that older drivers are a risk to. My parents friends are in their early 80's and no agency will rent a car to them if they fly to NY from FL.

It depends upon what company you work for.
