(In appropriate jurisdictions, replace "right" with "left".)

There are various and sundry laws in different jurisdictions about
passing another vehicle on the right.

What the law says doesn't matter. What matters is that

WHEN YOU PASS A VEHICLE ON ITS RIGHT
YOU ARE BETTING YOUR LIFE THAT IT WON'T TURN RIGHT.

You don't want to make that bet unless you are sure that you will win.
