Driving in another country can make a trip more flexible, particularly when you want to explore places that are difficult to reach by public transportation. However, having a valid driver’s licence at home does not necessarily mean you have all the documentation required to drive abroad.
An International Driving Permit (IDP) can provide supporting information about your driving credentials and may be required or useful when travelling to certain countries. Requirements vary considerably, so travellers should check the rules that apply to their destination and domestic driving licence before departure.
What Is an International Driving Permit?
An International Driving Permit, commonly known as an IDP, is a standardised document that supports a valid domestic driving permit when someone drives in another country. It can make information from a driver’s licence easier for authorities and other relevant organisations to understand, particularly when the original licence uses a different language or format.
An IDP should not be viewed as a replacement for your regular driving licence.
International Driving Permits are addressed within international road-traffic frameworks, including the 1949 Geneva Convention on Road Traffic and the 1968 Vienna Convention on Road Traffic. The applicable requirements can depend on the countries involved and the relevant convention or domestic rules.
Under the 1968 Convention, an International Driving Permit is intended to be used together with the corresponding domestic driving permit rather than as a standalone driving licence.
Travellers should therefore check the official driving requirements of their destination before travelling.
Why Might You Need an International Driving Permit?
The main reason travellers obtain an IDP is to make their domestic driving credentials easier to recognise internationally. Countries have different licensing systems, languages, road regulations and requirements for foreign visitors.
An IDP may be useful when local authorities need additional documentation to understand a domestic licence. It can also be relevant when renting a vehicle, particularly when a rental company’s documentation requirements differ from the minimum requirements under local law.
An IDP can also assist when dealing with traffic authorities because it presents key driving-licence information in a standardised format.
However, possessing an IDP does not automatically give someone permission to drive in every country.
The laws and regulations of the destination remain the determining factor.
Is an IDP Required in Every Country?
No. There is no universal rule requiring an IDP in every country.
International driving requirements can depend on several factors, including:
- The country you are visiting
- The country that issued your domestic driving licence
- The language and format of your licence
- The duration of your visit
- Applicable international road-traffic agreements
- National or local driving regulations
The United Nations Economic Commission for Europe (UNECE) maintains information about international road-traffic conventions, including the 1949 and 1968 conventions.
Before travelling, check:
- Whether your destination recognises your domestic driving licence
- Whether an IDP is required or recommended
- Which type of IDP or convention applies
- How long visitors may legally drive using foreign credentials
- Whether your rental company requires additional documentation
- Whether your insurance covers driving in the destination
- Whether additional vehicle documents are required
If your trip includes several countries, check the requirements for each country individually rather than assuming that the rules of your first destination apply throughout the journey.
How Does an IDP Help With Language Differences?
Language is one of the practical reasons an IDP can be useful.
A domestic driving licence may contain information that is difficult for officials or organisations in another country to interpret. An IDP uses a standardised format intended to make key driving information more understandable across borders.
This can be particularly useful when travelling somewhere where your domestic licence is written in a language that local authorities or organisations may not readily understand.
For example, imagine renting a car during an international trip and presenting a licence issued in an unfamiliar language or format. Supporting documentation containing standardised driving information can make it easier for the rental company to understand the relevant details.
An IDP is therefore best understood as a supporting document—not as a new licence replacing your existing domestic driving licence.
Renting a Car Overseas
Car rental is one of the situations where travellers commonly encounter questions about international driving documentation.
Rental companies may establish their own documentation requirements. Depending on the destination and circumstances, a company may request a passport, domestic driver’s licence, IDP, payment card and other documentation before providing a vehicle.
This creates an important distinction:
Being legally permitted to drive in a country does not necessarily mean you automatically satisfy a rental company’s documentation requirements.
Before travelling, check both:
Government requirements: What documentation does the destination legally require from foreign drivers?
Rental requirements: What documents does your chosen rental company require before releasing a vehicle?
Checking both can prevent unpleasant surprises at the rental counter.
Travellers should also ensure that names and other important personal details are consistent across their driving and travel documents.
Understanding the IDP Application Process
The application process depends on the country where your domestic driving licence was issued and the organisations authorised to issue the relevant permit.
Applicants may need to provide information connected to their existing driving credentials. Depending on the issuing process, requirements can include:
- A valid domestic driving licence
- Identification information
- Passport-style photographs
- Application documentation
- Applicable fees
Requirements vary, so travellers should confirm the process with the relevant authorised issuing organisation.
Before applying, check that your domestic driving licence remains valid and that you meet the eligibility requirements.
It is also sensible to arrange the necessary documentation well before departure. Waiting until the last moment can create unnecessary problems if processing, verification or delivery takes longer than expected.
Be Careful When Applying Online
Travellers should exercise caution when searching online for international driving documentation.
Terms such as “international driver’s licence,” “international driving licence” and similar variations are frequently used online, but they should not automatically be assumed to describe an officially recognised International Driving Permit.
Before providing personal information or making a payment, check:
- Who is issuing or supplying the document
- Whether the organisation is authorised or otherwise appropriate for your circumstances
- Whether you meet the eligibility requirements
- Which convention or permit applies to your destination
- How the document will be issued or delivered
- Whether your destination recognises the documentation
- Whether you will still need to carry your domestic driving licence
When in doubt, consult the relevant government authority, embassy, consulate, automobile association or other officially recognised source for the destination and issuing country.
Driving in the United States With a Foreign Licence
Foreign visitors planning to drive in the United States should check the requirements that apply to the states they intend to visit.
An IDP may serve as supporting documentation for eligible international drivers, but it is not a U.S. state driver’s licence.
Driving-licence requirements in the United States are administered primarily at the state level. Travellers should therefore consult the relevant state motor-vehicle authority rather than assuming that one general rule applies everywhere.
For example, someone planning a road trip through California, Nevada and Arizona should check the applicable requirements for those states before departure.
Rental companies may also establish separate documentation policies.
A useful approach is therefore to verify three things before driving:
- State requirements
- Rental-company requirements
- Insurance requirements
This is particularly important for journeys involving multiple states.
Is an IDP the Same as an International Driver’s Licence?
Travellers may encounter terms such as “international driver’s licence,” “international driving licence” and “IDP licence” when researching international driving requirements online.
These terms can create confusion.
The internationally recognised document addressed under the relevant road-traffic conventions is generally known as an International Driving Permit (IDP).
An IDP should not be treated as a permanent international driving licence or as an independent replacement for a valid domestic licence.
Where applicable, it is intended to accompany the corresponding domestic driving permit.
Travellers should therefore carry their valid domestic licence whenever driving internationally, together with any additional documentation required by the destination.
What Should You Carry When Driving Abroad?
Preparing your documentation before leaving home can make international driving considerably easier.
Depending on your destination and circumstances, your travel documents may include:
- Valid domestic driver’s licence
- International Driving Permit, when required or appropriate
- Passport
- Vehicle rental agreement
- Insurance documentation
- Vehicle registration documents, where applicable
- Emergency contact information
- Relevant itinerary information
Keep required original documents secure but accessible.
Digital backups or photocopies can also be useful if documents are lost, but they should not be treated as substitutes where authorities require original documentation.
When Should You Apply for an IDP?
It is generally better to arrange international driving documentation before travelling rather than trying to resolve missing paperwork after arrival.
Start by identifying every country you intend to drive through.
For each destination, determine whether an IDP is:
- Required
- Recommended
- Unnecessary
Then identify which requirements apply based on the country that issued your domestic driving licence.
After confirming the applicable requirements, review the authorised application process and allow sufficient time for processing or delivery.
If using an online service, carefully review its eligibility conditions, documentation requirements, fees, delivery arrangements and destination information before completing an application.
A Practical Pre-Driving Checklist
Before driving internationally, ask yourself:
Licence: Is my domestic driving licence valid for the entire trip?
Destination: Does each country I am visiting recognise my domestic licence?
IDP: Is an International Driving Permit required or recommended?
Permit type: Which convention or permit applies to my journey?
Rental: Does my rental company require documentation beyond the legal minimum?
Insurance: Am I properly insured to drive in every destination?
Duration: How long can I legally drive using foreign credentials?
Vehicle: Are any registration, environmental, toll or other vehicle documents required?
Documents: Do the names and details across my licence, passport and booking documents match?
Completing these checks before departure can prevent avoidable problems during the journey.
Common Mistakes to Avoid
Treating an IDP as a Standalone Licence
One of the most important mistakes to avoid is assuming that an IDP works independently.
Where an IDP is applicable, travellers generally need to carry the corresponding valid domestic driving licence as well.
Assuming One Country’s Rules Apply Everywhere
Driving requirements can differ significantly between destinations.
This becomes especially important on multi-country road trips, where crossing a border can change the documentation requirements.
Checking Only the Rental Company’s Rules
A rental company allowing you to hire a vehicle does not replace your responsibility to comply with applicable driving laws.
Check official destination requirements as well as rental-company policies.
Leaving Documentation Until the Last Minute
Discovering missing documents at the airport or rental counter can disrupt a trip.
Checking requirements early provides time to resolve problems before departure.
Confusing an IDP With a Permanent International Licence
An IDP is connected to existing domestic driving credentials and subject to applicable eligibility and validity conditions.
Travellers should be cautious of services implying that an international document permanently replaces a government-issued domestic driving licence.
Where to Verify International Driving Requirements
Because driving rules can change and requirements differ between countries, travellers should prioritise authoritative information when planning an international driving trip.
Useful sources can include:
- National transport or motor-vehicle authorities
- Relevant state or regional authorities
- Embassies and consulates
- The United Nations Economic Commission for Europe for information about international road-traffic conventions
- Authorised issuing organisations
- Rental companies for their own vehicle-hire requirements
- Insurance providers for coverage requirements
Commercial information services can supplement this research, but they should not replace verification through relevant official or authorised sources.
About IDP Worldwide
IDP Worldwide provides information and application services relating to international driving documentation. Travellers considering such a service should review the applicable eligibility and destination requirements before applying and independently verify requirements with the relevant government or authorised authority.
Where appropriate, travellers can review the international permit application process through IDP Worldwide.
Final Thought
International driving can give travellers greater freedom to explore a destination, but that freedom comes with a responsibility to understand the rules before getting behind the wheel.
An International Driving Permit can be useful—and in some circumstances required—but it should be considered one part of a broader preparation process that includes your domestic driving licence, destination requirements, rental policies and insurance coverage.
The most reliable approach is simple:
Check the rules. Verify authoritative sources. Prepare the correct documents. Then travel.
A small amount of preparation before departure can prevent unnecessary complications once you are on the road.
