In NL a sign (including maxspeed) is assumed to apply "for the current section of road" i.e. until the next junction. In the UK on the other hand a maxspeed sign is assumed to apply "until further notice," i.e. until you pass another sign OR you enter/leave a built-up area (which is often a grey area in itself) OR you drive onto a different type of road with a different default speed limit.<br></p><p>Excepting special cases such as the Autobahn in Germany, there is ALWAYS a maxspeed, whether it is signed or not. Whether the absence/presence of a sign affects your legal footing is jurisdiction-dependent. In NL the offence is created by the presence of a sign - if there is no sign, then the default applies. In the UK, the offence is created by a legal document, which is not dependent on the presence of signs. If there is no sign, or if the sign says a different value, that can be offered to the court in mitigation, but the offence has still been "committed."<br></p><p>Bottom line: I can't see any added value from maxspeed:signed=no.<br></p><div> <br></div><p><br></p><p>On 2021-01-03 22:14, Mateusz Konieczny via Tagging wrote:<br></p><blockquote style="padding: 0 0.4em; border-left: #1010ff 2px solid; margin: 0" type="cite"><div>Surveying maxspeed is clearly useful and relatively[1] simple.<br></div><div> <br></div><div>But surveying and tagging cases where there is no signed maxspeed and<br></div><div>it default to what is specified by law is often problematic.<br></div><div> <br></div><div>(1) we have no tag for "there is no maxspeed signage applying here"<br></div><div> <br></div><div>(2) default maxspeed rules are often extremely complex<br></div><div> <br></div><div>For example Poland has separate speed limits for<br></div><div>- vehicles below 3.5t<br></div><div>- vehicles with trailer or above 3.5t or trucks<br></div><div>- buses<br></div><div> <br></div><div>(3) tagging exact max speed is often de facto impossible as it<br></div><div>requires remembering that there are separate rules for<br></div><div> <br></div><div>- dual carriageway with 2 or more lanes in each direction<br></div><div>- dual carriageway with 1 lane in each direction<br></div><div>(Poland)<br></div><div> <br></div><div>- roundabout<br></div><div>- urban road that is not a roundabout<br></div><div>(El Salvador)<br></div><div> <br></div><div>- road without asphalt or concrete surface<br></div><div>- road with asphalt or concrete surface in an unincorporated area<br></div><div>(Alaska)<br></div><div> <br></div><div>For more gory details <a rel="noopener noreferrer" target="_blank" href="https://wiki.openstreetmap.org/wiki/Default_speed_limits">https://wiki.openstreetmap.org/wiki/Default_speed_limits</a><br></div><div> <br></div><div>(4) tagging exact speed limit info therefore requires both survey to confirm<br></div><div>that no signed speed limits applies and legal analysis (or using output of that)<br></div><div>and extra information.
