Many travellers ask whether they need to have an international driver's license for their road trip in California or elsewhere in the U.S.

The answer is simple: it is best to have an international license when driving in the U.S. if you want to avoid any hassles and rent a car without difficulties. However, it is not mandatory.

According to U.S. law, your ESTA travel authorization and a valid license from your country of residence should be enough to rent a car.

But in practice, more and more car rental companies require an international license to rent a car. For this reason, it is advisable to find out before your USA road trip which companies require an international license.

Note that your license must use the Latin alphabet.

Principal and additional drivers must have had their driver's license for at least 12 months.

These conditions are different for car rental in Canada.

To rent a car in Las Vegas or elsewhere in the U.S., you must be at least 21 years of age and have a credit card in your name for the deposit.

In addition, please note that drivers from 21 to 24 years of age are required to pay an additional fee to cover the higher insurance cost. This fee is about $30 a day.

Note that the driver's license of the principal driver and the credit card used for the deposit MUST be in the same name.

For a Western USA road trip or elsewhere in the U.S., child car seats must meet NHTSA Federal Safety Standards.

If your seat meets these standards, bring it! It’s free on the plane and your child will be as comfortable as at home.

Child car seats with an ISOFIX or LATCH system are authorized by car rental companies and the government.

If your seat does not have a LATCH/ISOFIX system or it is not certified FMVSS, you will not be covered by the rental company's basic insurance or additional insurance options .

In that case, you will need to rent a car seat with your vehicle. This option will be payable in advance or at the rental office, depending on the rental company.

Note that not all rental companies offer this option.
