France to Spain by Car — No IDP, No Side Switch, Just Tolls & 120

For a French driver, Spain is about the easiest foreign country there is to drive in — no permit, no side switch, no language barrier on the road signs that matters. The single adjustment worth fixing in your head before you go is the speed: Spanish motorways top out at 120 km/h, not the 130 you are used to on the autoroute. Spanish radar is dense and unforgiving, and the first 20 km/h over typically runs around €100, so reset your cruise control the moment you pass Le Perthus.

Tolls work differently south of the border

France taught you to expect a péage on every fast road. Spain is more of a patchwork. The free autovías (A-roads) now make up most of the network after the government scrapped tolls on a string of former AP routes, while the remaining autopistas (AP-roads) still charge — typically the AP-7 along the Mediterranean and the AP-9 in Galicia. Barriers take cards, and your French Bip&Go tag works on most Spanish toll gantries through the interoperable Via-T system, so you can keep the same transponder on the windscreen.

What stays the same — and the few things that don’t

You drive on the right, the alcohol limit is the same 0.05 you know at home, and 112 is the shared emergency number, so none of that needs relearning. Spain does insist on a warning triangle and a reflective vest in the car — standard kit you’d carry in France anyway, but worth checking a hire car actually has both, because the fine falls on the driver, not the rental firm.

Two smaller habits catch French visitors. Spanish urban limits dropped to 30 km/h on single-lane city streets in 2021, lower than you might assume, and enforcement in Barcelona and Madrid is camera-heavy. And in the cities themselves, low-emission zones (ZBE) now gate the centres of Madrid, Barcelona and dozens of others — a hire car with Spanish plates is usually fine, but a French-registered car you’ve driven down needs to check registration.

Before you set off

Confirm you genuinely need nothing extra with the Driving Permit Checker — for an EU-to-EU trip it’ll come back clear — and if you’re unsure how a Spanish speeding ticket compares to a French one, the Speeding Fine Calculator gives you a figure. The full rulebook, including the regional ZBE map, is on our Spain driving guide. Petrol sits around €1.70/litre; supermarket stations near the AP exits are reliably the cheapest fill.
