In 199l, Sweden introduced requirements for drivers applying for licences after having been sentenced for having driven with more than 0.015 BAC (blood alcohol concentration). The driver is required to present to the licensing authority a certificate stating that he/she is not dependent upon alcohol or other drugs, this certificate can be obtained from a doctor but only after a minimum of three months observation. During this time, the applicant has to see the doctor on a number of occasions and liver enzyme testing will be applied. After this period, if no problems are found, the driver can obtain a conditioned license after passing the written and the practical driving test. The conditions last for at least 18 months for at least 18 months during which he/she has, to see the doctor at least three times to prove that a relapse has not occurred. (A)
