De quel côté de la route conduit chaque pays
Environ un tiers des pays du monde roule à gauche, principalement d'anciens territoires britanniques, plus le Japon, l'Indonésie et la Thaïlande. Tous les autres roulent à droite. Les voitures de location ont généralement la même configuration locale de transmission (embrayage à gauche dans les pays qui roulent à droite).

Notes
- Environ 35 % des pays roulent à gauche, soit environ 25 à 30 % du trafic mondial.
- À la frontière entre les deux côtés (par ex. Laos → Thaïlande change de côté), on utilise généralement un échangeur aérien avec feux tricolores.
- Les habitudes des piétons suivent le côté de circulation : dans les pays à gauche, regardez d'abord à droite.
Qui conduit à gauche, et pourquoi
Roughly a third of the world's countries require driving on the left, carrying about a quarter to a third of global traffic. The pattern is largely historical: Britain and its former territories — the UK, Ireland, Australia, New Zealand, India, South Africa, Kenya, Malaysia, Singapore and Hong Kong — kept left-hand traffic, as did Japan, Indonesia and Thailand for reasons of their own. Most of Europe, the Americas, China, Russia and the Middle East drive on the right, a convention spread by Napoleon and later reinforced in countries influenced by the United States or by continental Europe. The split is not about clock or geography but about which empire or reformer reached the country first.
Border crossings between driving sides
Only a few land borders connect a left-driving country to a right-driving one, and engineers have solved them in a memorable way: the flyover interchange. At the Friendship Bridge between Thailand (left) and Laos (right), and at several China–Hong Kong and China–Macau crossings, traffic swaps sides on a dedicated ramp or under a signal-controlled crossover. The result is that crossing such a border is far less dramatic than the rules suggest — you simply follow the lane markings and end up on the other side. Because these crossings are rare and sometimes poorly signed, checking the layout in advance is worthwhile if your route crosses one.
Renting a car on the "wrong" side
The mechanical layout of a car follows the country it is sold in, not the driver's habit. In a right-driving country the driver sits on the left with the gear lever in the middle; in a left-driving country such as the UK, Japan or Australia the driver sits on the right. Pedals are the same everywhere — clutch, brake, accelerator, left to right — so the main adjustment is spatial: your dominant hand and your sense of the lane's edge change sides. The classic first-drive mistakes are drifting toward the centre line and switching on the wipers instead of the indicator, since those two stalks are mirrored on right-hand-drive cars.
Pedestrians, cyclists and roundabouts
Habits follow the traffic. In a left-driving country, pedestrians look right first before stepping off the kerb, and cyclists ride with traffic on the left. Roundabouts run clockwise in left-driving countries and counter-clockwise in right-driving ones, and giving way is often to the right in the former and to the left in the latter — though the exact rule varies, so watch the signs. For a visitor, the highest-risk moments are the first ten minutes after picking up the car and any junction after a long drive, when instinct reverts to the home country's pattern. A deliberate pause at each junction closes most of that gap.
Licences, permits and paperwork
Driving side is only half the equation; the other half is whether you are allowed to drive at all. Most countries accept a foreign licence for a limited period, and many require an International Driving Permit alongside it — essentially a translation of your home licence, not a licence in itself. Some left-driving destinations, including Japan and parts of Australia, are strict about which permit is accepted and how long it is valid. Rental companies often ask for both documents and may impose a minimum age or additional young-driver fee. Check the destination's requirements before you book, because a valid home licence alone is not always sufficient.
