This type of restriction is probably a country specific thing. In Ontario Canada, you can make u-turns at intersections (regardless of the road is separation) if there is no sign indicating that you can't make the u-turn. Here's the information directly from the Ontario Ministry of Transportation:<br><br><a href="http://www.mto.gov.on.ca/english/dandv/driver/handbook/section2.6.11.shtml" target="_blank">http://www.mto.gov.on.ca/english/dandv/driver/handbook/section2.6.11.shtml</a><br><br></div>I realize that the link I sent previously is in the US but I suspect that it's the same policy there which is why the restriction is tagged like it is.<br><br></div>Since the tagging seems to be valid, does the Garmin format support this type of restriction? If not then it's probably a good idea to indicate this in the warning message. Maybe the message should also be changed to an info message if there's no problem with the data. Does anybody have other insights?<br><br></div>Thanks, Ben<br></div><div><br><div>On Sun, Jul 5, 2015 at 2:47 PM, Thorsten Kukuk <span dir="ltr"><<a href="mailto:kukuk@suse.de" target="_blank">kukuk@suse.de</a>></span> wrote:<br><blockquote style="border-left:1px #ccc solid;padding-left:1ex;"><span>On Sun, Jul 05, Ben Konrath wrote:<br>

<br>
</span>Beside that this particular type of restrictions doesn't make<br>
any sense to me, I would guess the GARMIN format does not support it.<br>
<br>
If the to and from ways are the same, I have never seen a sign forbidding<br>
u-turns. Only, if you have two ways, structural seperated. But then I<br>
should tag the street that way and the restriction will not be ignored.<br>
