Drive again, but only with an alcolock.

Short answer

18+ topic. Denmark has a voluntary and a mandatory alcolock scheme for drivers disqualified unconditionally for drink driving. The voluntary scheme is for a first offence between 1.2 and 2.0 per mille and lets you drive again early if you stay in it for the rest of the disqualification. The mandatory scheme applies above 2.0 per mille or on repeat offences: you must drive with an alcolock for 2 years after the disqualification, or wait 2 more years. The car starts only if the breath test shows under 0.5 per mille, and the fee is 2,700 kr. in 2026.

Why

  1. Voluntary scheme for 1.2 to 2.0 per mille.
  2. Mandatory scheme above 2.0 or on repeat offences.
  3. The car starts only under 0.5 per mille.

Details

During the drive you must blow again at intervals, and you have 20 minutes to stop safely before an alarm sounds.

Tip

Apply at borgerservice about 4 to 6 months before you want to start driving with the lock.

What may differ

The voluntary scheme also costs 2,145 kr. for a personal assessment and 4,289 kr. for alcohol treatment if needed (2026), plus the lock, its fitting and service.

Common misconception

With an alcolock you can drive any car.

What actually happens

The licence covers only vehicles fitted with an alcolock.
