There are two reasons why someone might be required to have an ignition interlock:
- an alcohol content restriction
- a conditional restoration.
Driving a vehicle without an ignition interlock when it is required can have serious consequences. One consequence is being charged with driving while license revoked by a law enforcement officer. This can lead to the termination of any conditional restoration and alcohol content restriction, ultimately revoking the license. If someone is under a conditional restoration and drives without an ignition interlock, it can revert them back to a state of permanent revocation, with a prolonged period before being considered for conditional restoration again. It is crucial to adhere to the requirement of having an ignition interlock if it has been imposed as a restriction.
