Roadcraft is the official Police Driver's Handbook and is used by the police service to train police drivers. It is also the recognised 'bible' for advanced and emergency response driver training and essential reading for driving instructors and any driver wishing to improve their skills and safety to a more advanced level.
A map has such small print, it's impossible to safely read it while driving. If you are needing to find a specific address, write out the basic directions in large writing and short sentences, before you drive there. If you must read the directions (not the map) while on the road, do it where you are stopped.
