abstract fun withAllowVignettes(allowVignettes: MutableList<String!>!): T
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 avoidVignette with all countries but X. Using withAllowVignettes with an empty list is the same as avoiding all toll roads with vignettes. It is an error to use both withAvoidVignettes and withAllowVignettes.
