Is there any method to know the Country which is driving on left or right?(QtLocation)

We use QtLocation to make a navigation application.

We find there is a difference bettown the left-driving and right-driving country when come across an U-trun. In UK, f.ex. one should rather UTurn Right, but  in USA, one should rather UTurn Left. 

It is a static number in the current qt source. qtlocation/src/location/maps/qgeorouteparserosrmv5.cpp                                          static QGeoManeuver::InstructionDirection instructionDirection(const QJsonObject &maneuver) 

else if (modifier == QLatin1String("uturn"))
return QGeoManeuver::DirectionUTurnRight;

So,is there any method to know the current Country which is driving on left or right?
