Traffic rules
Worldwide
1. Worldwide
Traffic rules differ from country to country, but many basic principles are shared around the world. Countries may drive on the left or right side of the road, use kilometres or miles per hour, and follow different systems for speed limits, priority, parking and road markings. Traffic signs also vary: many countries use European-style red triangular warning signs, while others use systems such as the yellow diamond warning signs common in North America and parts of Oceania.
International agreements have helped make cross-border driving more consistent, especially for road signs, driving permits and vehicle standards, but there is no single worldwide traffic code. Every country sets its own traffic laws and enforcement rules. This worldwide section highlights common traffic-rule concepts, international differences and sign systems, making it easier to compare how driving works across different countries and regions.

Do all countries drive on the same side of the road?
No. For example, the United Kingdom and Ireland drive on the left, while Belgium drives on the right. Check the driving side before travelling and take particular care at junctions and roundabouts when changing between systems.

Are road speeds and distances always shown in the same units?
No. For example, British speed limits are expressed in mph, while Belgian limits are expressed in km/h. Read the local signs and use the correct speedometer scale rather than assuming that a familiar number has the same meaning abroad.

Are traffic signs identical in every country?
No. The Vienna Convention provides an international framework for road signs, with permitted national variations. The United States uses the Manual on Uniform Traffic Control Devices. Learn the signs used at your destination rather than assuming that every colour, shape or symbol has exactly the same meaning.

Can stop and give-way signs use different words?
Yes. Under the Vienna Convention, the STOP inscription can be in English or the language of the country, and national sign designs can vary within the convention. Recognise the stop and give-way sign shapes, read any local wording and comply with the local rule.
Does traffic from the right always have priority?
No. Belgium normally applies priority from the right at uncontrolled junctions, subject to its statutory exceptions. Other countries use different rules; British crossroads without signs or markings do not automatically give priority to one approach. Check the local rule and follow signs, signals and police directions.

Are daytime lights, winter tyres and safety equipment required everywhere?
No. Lighting, winter-tyre and equipment rules differ by country, season, weather, vehicle category and sometimes the country where the vehicle is registered. Check the destination’s official rules before travelling, including any requirements to carry or wear safety equipment.

Is a foreign driving licence or International Driving Permit valid everywhere?
No. Recognition depends on the destination, licence, vehicle category and length of stay. An International Driving Permit accompanies the underlying licence; it does not replace it. For example, Japan recognises specified foreign licences and IDPs, while mainland China requires an appropriate Chinese driving permit.

Are child-seat requirements the same in every country?
No. For example, the United Kingdom normally requires a child seat until age 12 or 135 cm, whichever comes first, while France normally requires an appropriate restraint for children under 10. Check the destination’s age, height, seating and exemption rules before travelling with children.

Do drivers pay road charges in the same way everywhere?
No. Austria uses a vignette for many motorway journeys in light vehicles, while Norway uses electronic toll collection that also covers foreign vehicles. Check the route, vehicle category and payment procedure before travelling; a vignette bought for one country does not cover another.
