Correct answer: 0.15 milligrams per liter.

During the second year of holding your first driver's license, you are still subject to the lower limit for novice drivers. If you are of legal age, you must not exceed 0.15 mg/l in exhaled air. The general limit of 0.25 mg/l applies once you have held your license for two years.
