Implied speed limits

I live in a residential area of Texas where the speed limit is not posted but is implied by traffic codes to be 30 mph. Should I enter maxspeed=30 mph for these roads or should I omit the maxspeed field? In other words, does “maxspeed” apply only to posted speeds?

It would be appropriate to enter maxspeed for all roads where it applies, even if it is not posted. There has been talk of being able to apply maxspeed to a city boundary relation for example and having apply to every road without a maxspeed tag, but that has not been an official standard yet (no one tags this way and none of the data users interpret this).

You might want to add source:maxspeed=* to indicate that the speed limit is implied by traffic codes and not posted explicitly.

Will do. Thanks for the advice.
