Perhaps in your part of the world, but not everywhere. Crossing solid 
lines, as centrelines or lane separators have exceptions for ordinary 
vehicles (not just emergency vehicles) here. Yet another example of how 
local influences must be applied to documentation. The page showing how 
highway types are interpreted in different countries may be copied for 
such definitions.

On the other hand, maybe we should stop kidding our selves that OSM, as 
a wiki, can ever reflect the legal situation, since anyone can change it 
at any time. Maybe we should try to map the physical characteristics and 
leave the legal interpretation to the drivers who are required to 
interpret what they see on the ground before them and cannot rely on any 
map or database for legal guidance. Every pair of hands on a steering 
wheel comes with a free brain.
