In Argentina we have a general rule. If you are driving in a two way
highway (residential, primary, secondary, etc) you can't turn left.
You can do it only if there is a sign and/or traffic light with the
turn left row. We are discussing in the Argentina forum about if it's
make sense to map the no_turn_left restriction on every crossing road
or not. I think that we should drive the exception to the rule, the
routing software should apply the default restriction.
You should map the exceptions (where left-turn IS allowed).
Don't know what to call them instead of no_left_turn. Maybe left_turn or
left_turn_allowed.
In states in the US where U-turns are allowed unless specifically
prohibited by a sign, we map only no_u_turn where it is prohibited, not all
the places where it is allowed.
There was some discussion in the past about creating defaults for various
rules such as these turning rules, speed limits, etc. tagged on
administrative boundaries (country, state, county, etc.), for use by
routing software.
