Can you drive in Washington with a Taiwanese license?

Yes, visitors can drive in Washington on a valid Taiwanese licence for up to 1 year.

The Washington State Department of Licensing states that visitors may use an out-of-country driver licence for up to 1 year. This matches RCW 46.20.025, which lets a nonresident aged 16 or older drive with a valid licence issued by their home country for up to one year.

Washington does not require an International Driving Permit for visitors. A valid Taiwanese licence is enough under state law.

RCW 46.20.025 allows a nonresident to drive with a valid driver licence issued by their home country and does not mention an International Driving Permit. The Department of Licensing also publishes no IDP requirement for visitors, so whether an IDP is helpful alongside a licence that is not in English is not addressed officially.

New residents may keep driving on a Taiwanese licence for 30 days after moving to Washington, then they need a Washington licence.

The Department of Licensing states you have 30 days after you move to Washington to get your driver licence. RCW 46.20.021 sets the same rule in law: new Washington residents must obtain a valid Washington driver licence within thirty days from the date they become residents.

A Taiwanese licence can be transferred through a special certification process. Contact the Taipei Economic and Cultural Office in Seattle to arrange it.

The Department of Licensing lists Taiwan separately from the standard no-test countries and directs applicants to the Taipei Economic and Cultural Office in Seattle (TECO). The process requires a translated certification, and the DOL tells applicants to contact TECO for details.

With TECO translated certification, Washington testing should be waived for an eligible Taiwanese licence; vision screening still applies. Current DOL guidance directs Taiwan applicants to TECO and requires translated certification.

Washington DOL currently lists Taiwan separately and tells applicants to contact TECO in Seattle, with translated certification required. A DOL Licensing Express post about the Taiwan reciprocity agreement says eligible Taiwan licence holders may skip the written and driving exams after proper translation and verification. Because the explicit waiver language is in an older supporting post rather than the current DOL table, keep this at medium confidence until TECO or DOL publishes a current direct statement.

Yes, a translated certification is required for a Taiwanese licence. It is arranged through the Taipei Economic and Cultural Office in Seattle.

The Department of Licensing testing page states that the Taiwan and Japan processes require translated certification and tells applicants to contact the respective offices for more information. For Taiwan that office is the Taipei Economic and Cultural Office in Seattle (TECO).

Bring your current licence, proof of identity, your Social Security number and payment for the fees to a Washington driver licensing office.

The Department of Licensing asks new residents to bring proof of identity including their current licence, payment for the driver licensing fee, and to tell the office their Social Security number. Acceptable identity documents are set out on the DOL proof of identity page and include foreign passports with valid immigration documentation.
