Dan - Police Office with several years of police driving experience on my c.v. (trained at Hendon as a young cop!) But - I'm still leanring how to drive - still assessing each drive and evaluating it.

(Same on bikes - motor and pedal - and COAST is always in the back of my mind.)
As for getting copped on the A road (which think I may have driven on some time on a holiday or something..),

if yu saw no repeater lollies - then think your C
O A S T needs a shake up. You usually do see them, though I do admit that foliage in some areas leaves a lot to be desired

(:bunker: - pun not intended!

Glad you have ordered copy of Road Craft. If you go on assessed drive with IAM - criticism would be constructive and well intentioned. I would also consider booking a couple of hours with an ADI just to identify any bad habits to work on as well if the IAM branch is one which does not do preliminary assessment. Also - purchase "Know Your Road Signs" and "Driving the Essential Skills" - plus a new copy of the Highway Code!
Browse in the motoring section of your local bookseller and check out any works by John Lyons, Paul Ripley., Peter Amey and Tom Topper as well as AA's "Expert Driving" and "IAM - How to Become an Advanced Motorist". Up to you to add to your bookshelf - they adorn mine anyway!

By the way - they all say COAST in their own way!
But remember - COAST is a set of good practice principles and if you follow this - you are usually at the safest speed for the road (usually around the speed lmit +/- 10% ) - and because COAST means you actually see the lollipops and the lurking vans - you are usually safe!

from me!

and my lads and lasses!
