Renting a Car Abroad: Complete Guide 2026

An International Driving Permit is an official translation of your driver's license into multiple languages. Some countries legally require an IDP for foreign drivers, while others accept it as a supplementary document. An IDP does not replace your regular license -- you must carry both. Countries that require an IDP for non-EU visitors include Italy, Greece, Austria, Japan, Thailand, and Brazil. Countries that generally accept foreign licenses without an IDP include the United Kingdom, France, Spain, Portugal, the United States, Canada, and Australia (for visitors from other English-speaking countries). Even where an IDP is not legally required, carrying one is recommended. If you are involved in an accident or traffic stop, an IDP provides a clear, standardized document that local authorities can read. Some rental company franchise operators may also request an IDP at pickup. Obtain your IDP from your home country's automobile association (AAA in the US, AA in the UK, ADAC in Germany) before traveling. Processing takes 1-4 weeks, and the cost is typically USD 20-30 or EUR 15-25. An IDP is valid for one year from issue.

If you plan to drive your rental car into a different country, you must inform the rental company and verify their cross-border policy. Not all companies permit cross-border travel, and those that do may charge additional fees or require specific insurance upgrades. Within the European Union, most major brands allow cross-border travel between Western European countries with advance notification. Fees typically range from EUR 0 (included in many premium brand rentals) to EUR 50-100 for specific country combinations. Common restrictions include Eastern European countries (some brands prohibit or charge premium fees for travel to Poland, Czech Republic, Hungary, Romania, and the Balkans), ferry crossings (taking the vehicle on a ferry to the UK, Ireland, or islands may require additional permissions), and one-way international returns (returning in a different country from pickup is available but can carry surcharges of EUR 100-500+). In North America, US-Canada cross-border rental is widely available with most brands at modest fees. US-Mexico border crossing is heavily restricted, with most major brands prohibiting it entirely. Always declare cross-border intentions at booking, not at the counter. Undeclared cross-border travel voids your insurance coverage.

Transmission availability varies dramatically by region. In North America, the Middle East, and Australia, automatic transmission is standard and included at no additional cost. In Europe, manual transmission is the default for economy and compact categories. Automatic vehicles are available but typically cost EUR 5-15 more per day and must be specifically requested at booking. If you cannot drive a manual transmission, it is essential to book automatic explicitly and confirm the booking guarantees automatic -- not lists it as a preference. 'Subject to availability' means you may arrive to find only manual vehicles available. In Japan and some Asian markets, automatic transmission is standard. In Africa and South America, availability varies significantly by country and operator.

European toll systems vary significantly by country, and understanding the local system before you drive is essential to avoid unexpected charges. Motorway toll booths (France, Spain, Italy, Portugal partly): Take a ticket on entry, pay on exit by credit card or cash. This is the most straightforward system. Vignette sticker systems (Switzerland, Austria, Czech Republic, Slovenia, Hungary, Romania, Bulgaria): Purchase a windshield sticker that grants unlimited motorway access for a fixed period (typically 10 days or 1 month). Check whether your rental vehicle already has a valid vignette. Electronic-only tolling (Portugal SCUT, some Spanish routes, new UK zones): No physical booths -- overhead cameras record your passage. Payment must be set up in advance through the rental company's transponder or online registration. Congestion charges (London, Stockholm, Milan, Gothenburg): City-center entry fees charged electronically. Rental companies may provide payment services for an administrative fee, or you can pay directly online. In North America, electronic toll systems (E-ZPass, FasTrak, SunPass, TxTag) are increasingly standard. Rental vehicles typically have transponders, with tolls billed to your credit card plus administrative fees.

Smartphone navigation using Google Maps, Waze, or Apple Maps works well in most countries and is the most economical option. Download offline maps for your destination before traveling in case of limited mobile data coverage. A phone mount (suction cup or vent clip) is an essential accessory -- holding your phone while driving is illegal in most countries. Rental company GPS units typically cost EUR 8-15 or USD 10-15 per day and offer the advantage of being pre-configured for the local market. For a one-week rental, this adds EUR 56-105, making a personal phone mount and offline maps significantly more economical. If renting a GPS unit, it may be more cost-effective to purchase a basic GPS device for EUR 50-80 that you can reuse on future trips rather than paying the cumulative daily rental fee.

International rental insurance considerations go beyond domestic rentals. Your home country insurance may not extend to foreign rentals, and credit card coverage often has geographic exclusions. Before renting abroad, verify whether your personal auto insurance covers international rentals (many US policies do not extend beyond North America). Check your credit card's rental car coverage for country-specific exclusions (Iceland, Ireland, Jamaica, and Italy are commonly excluded or restricted). Consider purchasing travel insurance that includes rental vehicle damage coverage for your destination. Third-party excess insurance from European providers generally covers rentals across the EU but may exclude certain countries. Verify coverage for your specific destination. For long-term international rentals (30+ days), standard rental agreements and insurance products may not apply. Extended rental or leasing programs (such as Renault Eurodrive or Peugeot Open Europe) offer alternative structures with comprehensive insurance designed for longer stays.

Know the emergency number for your destination before driving. In the EU, 112 is the universal emergency number. In the US, call 911. In the UAE, call 999. In most countries, you must file a police report for any accident involving injury, significant damage, or disputes about fault. In Italy and some other European countries, police reports are required for all accidents regardless of severity. Keep the rental company's emergency hotline number saved in your phone. All major brands provide 24/7 assistance lines for roadside breakdowns, accidents, and theft. High-visibility vests and warning triangles are legally required equipment in many European countries. Verify that your rental vehicle is equipped with these items before departing.

For Western Europe, Sixt offers the best fleet quality, and Europcar provides the widest station network. For the United Kingdom, Hertz and Enterprise both deliver strong coverage and service. For the United States, Enterprise offers the best customer service and neighborhood locations, while Hertz provides the broadest airport coverage. For the Middle East, Hertz has the strongest regional presence with good premium vehicle selection. For Iceland, Hertz and Europcar have the strongest operations, though local operators often provide competitive alternatives with Iceland-specific expertise. For Mediterranean islands and resort destinations, book international brands for service reliability, even at slightly higher rates than local operators.
