Renting a car and driving abroad: licences, insurance, nerve

A rental car abroad is the difference between visiting a country and getting into its corners. It is also a small stack of paperwork decisions that people make badly at a counter, jet-lagged, with a queue behind them. Make the decisions at home instead; none of them are hard in advance.

The licence question

An International Driving Permit is a translation booklet that accompanies your real licence. Some countries require it by law, many rental desks ask for it regardless, and police in a few places fine its absence. It costs little, takes minutes at a CAA or AAA office, and cannot be obtained abroad, so the rule is simple: if you are renting outside Canada and the US, get one before you fly. Check your destination's entry on the government travel advice pages, which list the requirement country by country.

The insurance stack, decoded

• Collision damage waiver (CDW) caps what you owe if the car is damaged, usually leaving an excess or deductible you still pay.
• The counter upsell is insurance that reduces that excess toward zero. It is priced like impulse candy, per day, forever.
• Credit card rental coverage can replace some of this, but only if you decline the rental company's waiver, pay with that card, and your destination is not excluded. A few countries commonly are excluded, so read your card's certificate before trusting it.
• Third-party liability is the one that matters most and is typically included by law locally; verify rather than assume.
• Whatever you choose, video the car on pickup and return: every panel, the roof, the windshield, the fuel gauge. Thirty seconds that ends most disputes before they start.

The local rules that catch people

• Tolls and vignettes: much of Europe pre-sells highway access as a windshield sticker or digital pass; crossing a border without one is an automatic fine.
• Italy's ZTL zones: camera-enforced historic centres where your hotel booking, not your instincts, determines whether you may drive in. Fines arrive by mail for months.
• Left-hand traffic: book an automatic, take the first roundabout slowly, and put a sticky note on the dash for the first morning. It clicks within a day.
• Fuel: note diesel versus petrol before the first fill; the wrong nozzle is the most expensive mistake in this guide.
• Manual transmissions are the default in much of the world. If you need an automatic, book it early and expect to pay for the privilege.
• Crossing borders in a rental often needs written permission on the agreement, especially out of Schengen or into different insurance regions. Ask when booking, not at the frontier.
