<p>As lots of people frequently point out, what about emergency vehicles? They can (often) ignore legal restrictions, but not physical ones:</p>
<p>if(i_am_an_emergency_vehicle)</p>
<p> maxfoo = min(maxfoo:physical, maxfoo:legal)</p>
<p>else</p>
<p> maxfoo = maxfoo:physical;</p>

+1, there is also the synonym "maxwidth:legal" (IMHO not advisable, as this is the same than the more used "maxwidth")</blockquote>
<pre>That's what the maxwidth wiki page states, but it is strangely
inconsistent with maxheight. It really should be the same definition
for both, and I think the height variant makes more sense.
maxfoo = min(maxfoo:physical, maxfoo:legal)
Don't assume that legal =< physical. For example, many roads have a
default legal max but didn't bother setting a legal limit on
individual chokepoints. When physical != legal, you may want to add
the subkeyed tag for the bigger value (or both), but most data users
will only care about the simple key.
