allowVignettes

This is a list of 3-character, ISO 3166-1, alpha-3 country codes of countries in which toll roads with vignettes are allowed. Specifying allowVignettes with some countries X is equivalent to specifying avoidVignettes with all countries but X. Specifying allowVignettes with an empty list is the same as avoiding all toll roads with vignettes. Note: It is an error to specify both avoidVignettes and allowVignettes.
