As of July 1, 2018, a new law, House File 2338, goes into effect, and it radically changes the temporary restricted license (TRL) rules. There will be no periods of ineligibility, regardless of age, test consent or refusal, or how high or low the test result is. Almost everyone will be eligible for a TRL immediately.
The new law will no longer be a work or school permit, but simply a license to drive anywhere, anytime, without limit. It will require the individual to install and maintain an ignition interlock device on any vehicle they drive or own, pay the civil penalty, and maintain SR-22 insurance.
This also means that everyone who has a breath, urine, or blood test failure or refusal, an OWI conviction or deferred judgment, will have to have an ignition interlock device installed in order to obtain a TRL during the period they are revoked.
Those who already have a TRL with limitations may want to consider re-applying for this new license as of July 1, 2018. You should consult an attorney before deciding whether that would be the wise choice for you. There may be pros and cons to doing so.
