🚫 Penalties for non-installation / violation

If a conditional-license holder drives a vehicle without an IID, it is treated as unlicensed driving, subject to criminal penalties (imprisonment or fine), and the conditional license may be revoked again. Tampering with or removing the device, or having someone else start the vehicle, is also punishable.
