What is the expression/word for "going against traffic (flow)"?


Suppose you're driving in a one way street and see someone coming in the
opposite direction.

What's the most natural way to say something like "Hey, you're going against
traffic!"

I know how to say basically the same thing just re-wording a little:

> これは一方通行の道路だよ！ _This is a one way street!_

But I was wondering what's the word/expression to actually say "against
traffic" (to go against traffic, or to go/drive in the wrong way, etc).




> 逆走する

is the most common expression for that. Often heard on the news. Because of
the aging society, incidents of elderly people accidentally getting on
highways in the wrong direction, going backwards on one way streets, and so on
are increasing.
