Warning! No Ventilation. Open with Caution.

[Grizzly]

I passed a Lorne Stewart Peugeot earlier on the M5.
With the usual red and green stickers on it's boot plus the above,
Or words to that effect.

I have not seen this before, Quite clever really.
Covers a lot of options does it not?

I think it's to warning the fire brigade in the event of an accident that gasses could have built up as it's not got roof vent or anything. Got them on our vans.
