Cycling is allowed on just about all trunk roads in the UK. There are a 
few trunk (or primary) roads where cycling is banned, but they are 
exceptions (and signposted as such), so easier to just tag those as 
bicycle=no.

There is this page which specifies the default access restrictions for 
different highway types in various countries: 
http://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access-Restrictions
Though its currently lacking anything for the UK. It would be worth 
adding a table, then anyone making routing software can just check that 
page.
