I'm a little stuck... Click here to teach me more about this clue!

'what can clear the streets' is the definition.
I can't tell whether this defines the answer.

'immediately parking in berkshire town?' is the wordplay.
'immediately' becomes 'now' (I've seen this in another clue).
'parking' becomes 'p' (abbreviation on road signs).
'in' indicates putting letters inside.
'berkshire town?' becomes 'slough' (I've seen this before).
'now'+'p'='nowp'
'nowp' placed within 'slough' is 'SNOWPLOUGH'.

Can you help me to learn more?

(Other definitions for snowplough that I've seen before include "Vehicle seen in bad weather" , "move to stop slide?" , "Winter road clearer" , "Winter vehicle" .)

I've seen this clue in The Telegraph.
