靠边停。

You usually say this when you are a few meters away from your destination. You can say it as a standalone phrase, but adding a 师傅 (shīfu - master/driver) at the beginning makes it much smoother. If you are in a rush, you might say it twice for emphasis. Just make sure you are actually near a spot where a car can legally stop. Don't expect a driver to pull over in the middle of a six-lane highway!

Use it in any hired ride, like a Didi or a traditional taxi. It is perfect when you see your favorite coffee shop or realize you've reached your apartment gate. You can also use it when riding with a friend or colleague. It is the standard way to signal the end of the trip. If you are navigating for someone, this is your 'mission accomplished' signal.

Avoid using this in a very formal setting without adding some polite padding. If your boss is driving you, just barking 靠边停 sounds a bit like you are firing them. In that case, add a 麻烦您 (máfan nín - sorry to bother you) at the start. Also, do not use this on a public bus. The bus driver has a fixed route and will probably just ignore you or give you a very confused look.

In China, the relationship with drivers is unique. The term 师傅 is a respectful way to address someone with a technical skill, including driving. Using 靠边停 is part of the fast-paced urban life in cities like Beijing or Shanghai. It reflects the efficiency of Chinese street life. Interestingly, because traffic can be chaotic, this phrase is often followed by a quick check of the side mirror to avoid 'door-ing' a passing e-bike.

If you want to be extra polite, say 麻烦靠边停一下. The 一下 softens the command. If you see a specific landmark, you can say 在前边靠边停 (stop up ahead). If you are in a real hurry, you might just say 就这儿停 (stop right here). But 靠边停 remains the gold standard for clarity and safety.
