There are some companies that provide services of fare-paying conveyance of passengers without a Class II driver license, but with the permission of the motor vehicle official by interpreting the Article 80 of the Road Transportation Act beyond the realm of its original scope, which is so-called 'Article 80 authorized vehicle' (see abolished substitution bus Article 80 bus); however, many ordinary taxi operators have broken the force of an objection to the Ministry of Land, Infrastructure, Transport and Tourism saying that what those companies are doing is a Shiro-taku operation, which has somehow reached an understanding between these two types of companies through negotiations with the Ministry of Health, Labor and Welfare.
道路運送法第80条を拡大解釈し、普通二種運転免許を持たずとも陸運局の認可を受ければ旅客を有償運送できる、いわゆる「80条許可車両」（詳細は廃止代替バス80条バス参照）があるが、タクシー業界から「完全な白タクではないか」との強い異議が国土交通省に寄せられ、厚生労働省との折衝で現時点ではなんとか折り合いがつけられている状態である。
