According to this website I don't need to have an international drivers license to drive in Taiwan as long as I'm not staying for more than 30 days. I'm only staying for 5 days.
I have a valid American drivers license with me, but did not bring my Taiwanese drivers license with me. Other websites contradict the Taiwan DMV by saying yes, I do need an international drivers license, including the AAA website.
Can I use a foreign driver's license if I'm staying in Taiwan less than 30 days?
