Not true at all. Green signs are used for roads which are part of the Primary Route Network as designated by the DfT. We actually got a list of all the roads which make up the PRN from the DfT a year or two back using an FOI request. See wikipedia: http://en.wikipedia.org/wiki/Great_Britain_road_numbering_scheme#Trunk_roads_and_primary_routes > I mean if you look at the A2 it looks and feels like a Motor Way (Hard > Shoulder, Slipways, 70MPH) all the way till Wilmington it just happens > that Tractors and Learners are aloud to use it (I would not advise it > however).

Many tunnels and bridges deliberately lose the motorway classification of the road which passes through them in order to allow otherwise prohibited traffic to use them. Hence why the QE2 bridge and Dartford tunnels are designated as the A282 and not the M25. In fact I can't find any map which shows either the tunnel or the approach roads as the A102(M) - they all shown as the A102 for the whole length from the junction with the A12/A13 to the north to the junction with the A2 to the south.
