Roland Perry gurgled happily, sounding much like they
were saying:

I leave the M25 at Chorleywood and I am glad that I don't join the
motorway here in the morning. The queues are often back to the Sarrat
turn.

What are the queues like at J17, which is where the OP would have been
exiting?

Non-existant, for Chorleywood, but it's a bit back-lane.
It can be a bit slow heading towards Ricky, though.
