In my experience, the Sudden Type 44 Fogging (Rapid Deployment Variant)
is always a blocked drain.

My own event wiped out all exterior vision in around 50 yards of exit
slip road, leaving me blind in two lanes of fast traffic coming off the
M40 onto the A43.

I've since dealt with three or so others.
