For how long can a person from another country drive in the U.S. with just their driver's license from that country?

In the United States, individuals from other countries can typically drive using their foreign driver's license for a limited period. The most common duration recognized across various states is up to one year. This is because the US allows visitors to drive with their valid foreign licenses as long as they adhere to the individual state laws, which often use this time frame.

While some states may have specific regulations or shorter durations, one year is a widely accepted standard that accommodates the needs of international travelers without requiring them to obtain a local driver's license immediately. Therefore, this option reflects the general consensus among state laws and practices regarding the validity of a foreign driver's license for driving in the U.S.
