In European countries, it is forbidden to perform U-turn at an intersection (see R. 412-19 in France, similar rules exist in other countries). Yet, every time I link two roads together (I create an intersection), it appears with no restriction for U-turns at the intersection point. At the moment I just select the intersection and add the U-turn restriction manually; this is cumbersome and really not practical. I'm using iD. Whenever I drive off the suggested route, my routing engine (OsmAnd offline) tells me to turn around precisely at those points. I would like my routing engine to stop suggesting illegal maneuvers. What is a good suggestion for this? |

I'd suggest contacting the authors of the router itself. Osmand has a Google Group; you can try there. Incidentally; rules such as this would have to be applied by country. Certainly not all European countries have this rule. |
In European countries? I'm pretty sure this is allowed in Germany on every intersection where it isn't explicitly forbidden. Except from a few corner cases where it would obviously be too dangerous.
Also legal in Czech Republic - except at traffic-light-controlled intersections and where explicitly forbidden.
