Nimes Garons Airport Car Rentals: Best Rates & Zero Hidden Fees

You'll need both your valid US driver's license AND an International Driving Permit (IDP) to drive in France. The IDP serves as a certified translation and is mandatory for US citizens. You can obtain one through AAA before departure (about $20). Without an IDP, you risk fines of up to €135. The minimum driving age is 18, but most rental companies require drivers to be at least 21, and drivers under 25 typically pay a young driver surcharge of €25-35 per day.

French highways (autoroutes) use a mix of automated toll booths accepting credit cards and cash, plus the télépéage electronic system. If you're planning to drive more than 200km on toll roads, renting a transponder (about €10-15/day) is cost-effective—it lets you pass through telpéage lanes without stopping. Toll costs average €0.10-0.15 per kilometer; the 120km drive from Nîmes to Montpellier costs about €12. Cash and card payments are always available at manual booths.

Urban areas: 50 km/h, rural roads: 80 km/h, dual carriageways: 110 km/h, highways: 130 km/h (reduced to 110 km/h in rain). Speed cameras are widespread and fines arrive by mail within weeks—typically €45-150 depending on how much you exceed the limit. Flash of headlights to warn oncoming drivers of speed traps is actually illegal and can result in a €75 fine. A 20 km/h overage on highway triggers an immediate €135 fine.

Most French rental cars run on diesel (gazole) or gasoline (essence/SP95). Diesel is significantly cheaper (about €1.50/liter vs €1.70 for gasoline) and offered on most economy rentals. Premium diesel (B7) is standard. If you're handed a gasoline car, look for SP95 or SP98 labels at pumps. Never use diesel in a gasoline car—the error can cost €300-500 in repairs. Most rentals operate on a full-to-full fuel policy; bring €10-20 in cash for rural gas stations that don't accept US cards.

Cross-border trips to Spain, Italy, or Switzerland require prior authorization from your rental company—typically €30-50 for European Union trips, more for non-EU countries. You must request this when booking, not at the counter. Some companies prohibit cross-border travel entirely. Within the Schengen Zone (France, Spain, Italy, Germany, etc.), border crossings have no formal checks for rental vehicles. Monaco and Andorra are accessible without special authorization from France.

Nîmes-Alès-Camargue-Cévennes Airport (FNI) is small with major rental companies (Hertz, Avis, Europcar) open 6am-11pm daily. The 15-minute drive to Nîmes city center costs €30-45 by taxi. Note that airport rental cars often have higher insurance excess (€1,500-2,500) than city locations. If arriving on TGV trains at Nîmes Centre, city-based rentals typically offer better rates and no airport surcharges—plus downtown is walkable for sightseeing. Parking at the airport costs €15-25/day versus €8-15 in central lots.
