Okay, the user wants me to translate "overtaking lane" into Thai. Let me check the translation rules again. The first rule says to translate all content into Thai. The second rule states that if the content is already in Thai, leave it as is. The third rule is to provide only the translation without any explanations.
So, "overtaking lane" is an English phrase. I need to translate it into Thai. The correct translation for "overtaking lane" in Thai is "เลนแซง" which is commonly used in Thai traffic contexts. I should make sure there's no existing Thai text here, which there isn't. Just need to output "เลนแซง" without any extra text. Let me confirm once more that I'm not adding any explanations. Yep, just the translation. Alright, that's it.
