Driving Requirements
EU/EEA licence holders may drive in Spain indefinitely with their home licence, no translation or International Driving Permit (IDP) is needed. Visitors from non-EU countries (including the US, UK, Canada, and Australia) may use their national licence for up to six months from the date of entry. Beyond that period a Spanish licence is required. The UK licence is accepted for six months under the current bilateral arrangement. But carrying an IDP is recommended for non-EU drivers as some officers and rental desks expect one.
Spanish law sets the minimum age to hold a full driving licence at 18. Rental company policies are a separate matter and vary significantly by provider: some companies will rent to drivers aged 18 or 19, while many set their floor at 21 or 25, and most charge a 'young driver' surcharge for anyone under 25. Check your specific rental company's terms before booking, as this is a commercial policy, not a legal one.
Spanish law requires all vehicles to carry third-party liability (responsabilidad civil obligatoria) as a minimum, rental vehicles come with this included by law. Rental companies typically offer additional coverage tiers: Collision Damage Waiver (CDW), theft protection, and Super CDW (which reduces the excess to zero). These extras are rental company products, not legal requirements, and their terms vary by provider. Your personal travel insurance or credit card may already include some coverage.
Virtually all rental companies in Cadiz require a credit card in the main driver's name at pick-up, debit cards are generally not accepted, and prepaid cards are typically refused. A security deposit (pre-authorisation) is held on the card and the amount varies by company and vehicle category. Check current deposit amounts with your specific provider at the time of booking. This is a rental company commercial policy, not a legal mandate.
Spain drives on the right, and overtaking is on the left. Turning right on a red light is prohibited unless a green filter arrow is displayed, this surprises drivers from North America where right-on-red is often permitted. At uncontrolled intersections, priority belongs to traffic coming from the right. In urban areas, speed limits are typically 30 km/h on single-lane streets and 50 km/h on multi-lane roads; Spain uses a points-based licence system and fines are issued on the spot to foreign drivers.
Helpful Tips
Cadiz has no commercial airport. The closest is Jerez de la Frontera (XRY), roughly 35 km away, with Seville (SVQ) about 120 km out. Picking up at XRY saves a transfer and typically has a broader fleet. But since cars are largely impractical inside the old-town peninsula, a city-center pickup after arriving by train or bus is often the smarter choice.
Before accepting the rental company's Collision Damage Waiver, check whether your credit card or travel insurance already covers CDW for Spain, as many premium cards do. Regardless of your insurance decision, photograph every existing scratch and dent with a timestamp before leaving the lot.
Google Maps works reliably across the Cadiz province for day trips to El Puerto de Santa María, Vejer, or the White Villages. But the old-town peninsula's tight one-way streets and pedestrianized zones can trip up GPS routing. Download an offline map as a fallback and watch closely for 'Zona Peatonal' and 'Acceso Restringido' signs.
Most Spanish rental companies default to a full-to-full fuel policy, though prepaid tank options exist at some companies. Diesel (signposted 'Gasoil' or 'Diésel') is common for mid-size rentals and is generally cheaper than petrol in Spain. Fill up on the outskirts or along the N-IV/AP-4 corridor, as fuel stations are sparse inside the old-town peninsula.
Parking in Cadiz's old town is scarce: the peninsula's street grid was not built for cars, permit zones dominate residential streets, and blue-zone (Zona Azul) pay-and-display fees apply on remaining streets during business hours. Use the paid underground car parks at the old-town edge near Puerta de Tierra rather than circling, and note that the newer Extramuros district near Playa Victoria has noticeably better street availability, though blue-zone fees still apply during the day.
Driving Warnings
The Casco Antiguo (historic old city) sits on an extremely narrow peninsula where many streets are one-way, resident-access-only, or pedestrianized; GPS devices frequently route drivers into restricted zones monitored by automated cameras, and fines are issued by post weeks after the visit.
Spanish law requires you to put on a high-visibility reflective vest before stepping out of a vehicle stopped on any road or hard shoulder, not after you have already exited; non-compliance carries an on-the-spot fine, and the vest must be kept inside the passenger compartment, not in the boot.
In July and August, the single narrow isthmus connecting Cádiz to the mainland, crossed by both the Puente Carranza and the Puente de la Constitución de 1812, becomes a severe bottleneck. Weekend afternoon traffic returning toward Jerez and the A-4 can back up for several kilometres, and there is no practical alternative route off the peninsula.
Spain's DGT uses average-speed enforcement (tramos de control de velocidad media) on major approach roads, including stretches of the A-4; these systems calculate your average speed between two fixed points, so slowing briefly at a visible camera while speeding between them still results in a penalty.
