How it's used
This term originated from the visual similarity between the black smoke emitted by poorly maintained vehicles and the ink released by cuttlefish. Drivers use this to warn others about environmental protection department checkpoints that monitor vehicle exhaust. The checkpoints themselves are colloquially referred to as 墨魚站.
Examples
There is a roadside emission test ahead, everyone drive slower.
Your car is emitting so much smoke, it is very easy to get caught in an emission test.

Common mistake
Do not use this term in formal or professional contexts, as it is strictly restricted to the subculture of professional drivers and vehicle enthusiasts. Using it with non-drivers will likely cause confusion as they will literally think you are talking about fishing.
