There are some taxi companies that hire people who have a right to take a Class II driver license (who took Class I driver license three years ago or before) as aspiring drivers and have them obtain a Class II driver license (many of the major taxi companies in Tokyo run a driving school as a group company, which can offer training to obtain a Class II driver license), but the people are usually tied to the company for a few years (most of the time, the aspiring drivers are supposed to agree to a contract saying "if he/she quits the company before the training period is over, he/she must pay back the cost for obtaining the license." before they were employed, but this is not legally binding).
二種免許の取得資格がある者（普通第一種運転免許を3年以上取得している者）を教習生として雇い、二種免許を取得させる事業者もあるが（都内の大手タクシー会社では、グループに自動車教習所を持っている場合が多く、ここで二種免許取得のための教習が可能）､その場合数年（おおむね1～2年）の拘束期間が発生する（この期間を終える前に退職した場合、取得費用を返還しなければならないという契約で雇用されている場合が多い。ただし、法的な拘束力はない）。
