Green Lane Association Limited (GLASS) is a national membership organisation and a company limited by guarantee, dedicated to protecting and preserving our national heritage of ancient green roads. GLASS represents over 4500 individual members in England and Wales, as well as members of affiliated clubs. GLASS owns Trailwise2, a national catalogue of green roads, and all our members sign up to comply with a drivers’ code of conduct. We promote sensible driving in the countryside on legal routes and are opposed to illegal ‘off-roading’ in any form.
