Editing Ignition interlock device (section)

====Denmark====
The [[Danish Road Safety Traffic Authority]] trialed the lock in 2015 in a voluntary program, which could replace a licence suspension of maximum two years. As there was a very poor uptake of only 24 drivers, they changed it in 2017 to a three-year programme which resulted in an improved participation rate of 450 drivers as of 2020.<ref name="etsc"/>{{rp|9}}
