How to Say “Drive safely” in Thai
ขับรถระวังด้วย
khàp-rót ra-wang dûay
Drive safely
นะ (ná) turns this into a gentle request rather than an order — and after นะ (ná), women say คะ (khá) (high tone), not the plain ค่ะ (khâ).
Word by word
When to use it
Since traffic in Thailand can be intense, the phrase ขับรถระวังด้วยนะ (khàp-rót ra-wang dûay ná) — Drive carefully — shows genuine care and concern. Thais frequently say this to family members before they drive off. For a more casual and highly common alternative, you can use ขับรถดีๆ นะ (khàp-rót dii-dii ná).
Why you've seen it spelled differently
You may have seen ขับรถระวังด้วย written as: khap rot rawang duay, kap rod rawang.
There is no single standard for writing Thai in the Roman alphabet — phrasebooks, road signs, and tourist guides each follow a different system, and many just invent their own spellings. The romanization on this page uses a consistent IPA-based system that marks all five tones and distinguishes short from long vowels. The same word always gets the same spelling.
