Our advice though (for Americans moving to France) is to NOT TAKE the driving test. How you might ask? Certain countries have an agreement with France that if citizens move from those countries to France they can simply trade their current license for a French one. In the US, there are some states which this agreement works with.
From the French embassy: "Driver’s licenses from the following states are eligible for exchange: Arkansas (limited to Class B), Colorado (limited to Class B), Connecticut (limited to Classes A and B), Delaware (limited to Class B), Florida (limited to Classes A and B), Illinois, Iowa (limited to Class B), Kansas, Maryland, Massachusetts, Michigan, New Hampshire, Ohio (limited to Class B), Oklahoma, Pennsylvania (limited to Classes A and B), South Carolina, Texas (limited to Class B), Virginia (limited to Class B), West Virginia."

If you don't have a license from one of these states, we strongly recommend getting one. If you do have a license from one of these states, here is the process to trade it for a French license:
We had Florida licenses so we took them today to trade them. We needed to provide a copy of our French residence card (carte de sejour), passport copy, driver license copy, 2 photographs, proof of address in France, completed application, and a professional notarized translation of our licenses done by a certified, government recognized translator (price varies, ours cost 45 euros for 2). We turned in the paper work and were told it takes 2-3 months to get our French licenses. They'll send us a text message when they're ready for us to pick them up. Then we'll have to surrender our Florida licenses for the French ones. We'll update this post when we get them!
UPDATE: As expected, we received the notice to pick up our licenses. We went to the local prefecture, took the number to wait in line and were quickly called up to the counter to pick them up. We had to surrender a temporary certificate we had received in the mail showing that our licenses were in process, as well as sign something. Pretty easy and straight forward and a WAY better option than trying to take the driving test here!
