Why driving-side knowledge matters
Arriving in a left-hand-drive country when you learned to drive on the right is a genuine cognitive challenge, and the reverse is just as true. The first junction is the hardest; after a day or two it becomes instinctive, but a clear mental reminder before you set off prevents the most common — and dangerous — mistake: pulling into the wrong lane on an empty road.
Knowing which side a country drives on also matters for pedestrians, who should look first in the direction of oncoming traffic when crossing. This guide tells you the side, the minimum age and the IDP situation for major countries at a glance.
The history of left versus right
Driving on the left predates cars: horsemen kept to the left so their right (sword) hand was ready to greet or defend an oncoming rider. Most of the world kept this convention until the 18th and 19th centuries, when France and then the United States popularised right-side driving — partly because freight wagons drawn by large teams were driven from the left rear horse, making it easier to judge oncoming traffic on the right.
The British Empire retained left-side driving, which is why the UK, Australia, India, South Africa, Singapore and others still drive on the left today. Japan drives on the left for its own historical reasons. Roughly two-thirds of the world now drives on the right.
International Driving Permits explained
An IDP is a small booklet that translates your domestic driving license into several languages, recognised under two international conventions (1949 and 1968). It is not a standalone license — you must carry your original license alongside it. Whether you need one depends on your issuing country, your destination and the length of your stay.
Some countries require an IDP by law for any foreign driver (Japan for most non-Japanese licenses, China which does not recognise foreign licenses at all). Others accept foreign licenses directly for short tourist visits. Always check the specific rule for your pairing of issuing country and destination; rental companies often enforce the requirement even where the law is ambiguous.
Minimum ages and rental rules
The legal minimum driving age is set nationally and ranges from 16 (some US states, Canada, New Zealand for restricted licenses) to 18 (most of the world). Rental companies impose their own minimums — typically 21, with a young-driver surcharge until 25 — which are independent of the legal driving age.
Some countries also impose a maximum rental age, and many require several years of driving experience on your license. If you are a new driver or over 70, check both the law and the rental terms before booking.
Local road rules worth learning
Beyond the side of the road, every country has quirks. Italy and many European cities have ZTL (limited traffic) zones that fine unauthorised drivers automatically via camera. Japan has strict rules on parking, including fines for parking on the street in some cities. Australia has strict speed enforcement and random breath testing.
Roundabouts, priority rules and overtaking norms vary. A few minutes with a local driving guide before you pick up a car saves fines and stress. The highway code of most countries is published online in English.
Practical tips for driving abroad
Before you drive, walk around the car to understand its controls (wipers and indicators are often on the opposite side when the car is built for the other road side). Adjust your mirrors before moving. Drive cautiously for the first hour to build muscle memory, especially at junctions and roundabouts where the wrong-side reflex is strongest.
Carry your license, IDP if required, passport and rental documents. Know the local emergency number and the rental company's breakdown line. And never assume right of way — give-way rules differ, and in a collision the foreign driver is often presumed to understand less than locals do.
Frequently Asked Questions
Do I need an International Driving Permit (IDP)?
It depends on your license's country of issue and your destination. Many countries accept foreign licenses for short tourist visits, but several — including Japan, China and parts of the EU for non-EU licenses — require an IDP. An IDP is a translation of your license; it is not a license on its own.
Why do some countries drive on the left?
Left-side driving dates to horse traffic and the practicality of keeping the right (sword) hand free to greet or defend. Britain, much of the former British Empire, Japan and a few others retained the practice; most of the world switched to the right in the 20th century, often influenced by France and the US.
Can I rent a car with just my home license?
Usually yes for short tourist rentals, but rental companies and local law can require an IDP for certain license-issuing countries. Check both your destination's law and your rental company's terms before you travel.
What is the minimum driving age worldwide?
Most countries set it at 18, though some allow learning at 16 or 17. A few allow restricted licenses earlier. Rental companies almost always impose their own minimum (commonly 21 or 25) regardless of the legal driving age.
Are road signs the same everywhere?
Most countries use the Vienna Convention road-sign system (pictograms rather than text), so signs are broadly recognisable. The US and a few others use text-based signs. Speed limits and meanings are mostly consistent, but local quirks — ZTL zones in Italy, give-way rules — are worth learning.
