"Neodjíždějme ještě."

Translation: Let's not leave yet.

Is "Let's not depart yet" a possible translation?

[BjrnMrtens]

Seems reasonable to me. I think it is less frequently used in this way though.

Don't let's leave yet - is a perfectly good colloquial equivalent

[AgnusOinas]

It's a bit dated and/or regional, but sure, can't say it's wrong.
