It is not necessary. You only need a passport or identity card and valid license from the country of origin. Only if the license is not printed in the Roman alphabet, an international driver’s license must be presented. If you are a foreigner: for the driver’s license to be valid, the holder must not have exceeded 90 calendar days from the date of entry into the country. This will be verified with the stamp of entry. Except for holders of licenses from Venezuela, Central America, and Colombia, driver’s licenses are valid in Costa Rica for a maximum of 30 calendar days from the date of entry into the country.
