Age Penalties

If you're under 25, you may have to pay an additional fee, usually about $25 per day. Those companies who will rent to drivers under 21 often charge much steeper surcharges (like $110 per day in the state of New York). Internationally, you'll not only see penalties for underage drivers but also for older ones -- those over 70 may have to pay extra (if they're able to rent at all).
