Federal Laws vs. Research

1. No interlock without prior period of hard license revocation for subsequent offenders.

2. Interlocked offenders may only drive to work, school, or treatment.

1A. Interlocks are more effective than hard revocation.1B. Most revoked offenders drive while revoked, DWR.1C. Offenders learn that they can get by with DWR.2A. Ignored and Ineffectual2B. Reduces sober-driving training.


Before 2012

2012 Highway Bill Removes Restrictions and Offers Grants

1. The Hard-revocation-period-before-interlock for subsequent offenders has been removed.

2. Federal restrictions on where and when an interlocked offender may drive have been removed.

3. Federal grants will be given to states that enforce an all-offender interlock law.

An Ignition Interlock is anElectronic Probation Officer

• Dedicated Probation Officer in Front Seat• On duty 24 hours per day• Tests and Records daily BAC’s • Allows only Alcohol-Free Persons to Drive• Reports All Violations to the Court/MVD• Costs Offender only $2.30 per day

(1 less drink per day)

Roth 4/14/13 2013 Lifesavers Conference

Punishes Probation Violations Immediately

Why Interlock Drunk Drivers?1. Interlocks are the most effective DWI sanction.

99.993% of Interlocked Days are No-DWI days*.

2. They are the most cost-effective sanction. The cost is $2.50/day paid by the offender.

3. They are perceived as fair by 85% of offenders4. 70% less recidivism than license revocation5. They are paid for by offenders6. They supply 24/7 supervised probation


* While 48,274 NM offenders were interlocked for 23,204,035 days, they had 1538 DWI arrests. That’s 1 arrest per 15,000 days

What Works?

1. All DWI offenders must be included2. Must be mandatory not just voluntary3. Avoid hoops: (pre-requisites to interlock)4. Close loopholes5. Compliance-Based-Removal6. Triage to stiffer (and more costly) penalties7. Indigent support8. Promotion of General DeterrenceRoth 4/14/13 2013 Lifesavers Conference 22

First Offenders are Biggest Problem

BAC Distributions by Arrest Number Are Similar


Main Key to an Effective Program

• The key to an effective interlock program is simply getting interlocks installed in the vehicles of arrested drunk drivers.

• Nothing else…( reporting, inspecting, sanctioning, monitoring)… is as important.

• These extra program components definitely add effectiveness, but they should be added only to the extent that funds are available.


Model Ignition Interlock Programby Dick Roth October 10, 2012 page 1 of 2

1. Mandatory Interlocks as a condition of probation for all convicted offenders. 1 yr. for 1st, 2 yrs. for second, 3 yrs. for 3rd, and 5 yrs. for 4 or more.

2. Electronic Sobriety Monitoring for convicted offenders who claim “no vehicle” or “not driving. Daily requirement of morning and evening alcohol-free breath tests as a condition of probation.(or $1000/yr. for supervised probation)

3. An ignition interlock license available to all persons revoked for DWI with no other restrictions. Allow MVD to set fee to cover cost.


Model Ignition Interlock Programby Dick Roth October 10, 2012 page 2/2

4. An Indigent Fund with objective standards such as eligibility for income support or food stamps.

5. Vehicle immobilization or interlock between arrest and adjudication. Offender’s choice……. By voiding Vehicle Registration until interlock is installed or offender is adjudicated not guilty ..(Alternative: Interlock as a condition of bond)

6. Vehicle forfeiture for driving a non-interlocked vehicle while revoked for DWI.

7. Compliance Based Removal: No end to revocation period before satisfaction of at least one year of alcohol-free driving with an IID. (e.g.. ≥ 5000 miles and ≥ 1 year with no recorded BAC>0.05 by any driver) .

8. Criminal sanction for circumvention of IID. 27Roth 4/14/13 2013 Lifesavers Conference

I.5. Triage Up in Sanctions• Extension of Interlock Period• Photo Interlock• Home Photo Breathalyzer• Continuous BAC monitoring• Treatment• House Arrest• Jail


III.6. What We Have Learned• Given a choice, most offenders choose revocation over

interlock …and they keep driving after drinking.• First offenders must be included because they are

60% to 80% of all DWI offenders, and almost as likely to be re-arrested as subsequent offenders.

• There must be an Interlock License available ASAP.

• Revoked offenders are 3-4 times more likely to be re-arrested for DWI than interlocked offenders.

• Hard revocation periods just teach offenders that they can drive without being arrested.

• Judicial Mandates get more interlocks installed than Administrative requirements.

Interlocks are Effective, Cost-Effective and Fair

• Interlocks reduce DWI re-arrests by 40-90%• They reduce the economic impact of drunk driving by

$3 to $7 for every $1 of cost.• Interlocks are perceived as a fair sanction by 81% of

over 15,000 offenders surveyed.

..But they only work if… you get them installed.

Administrative and/or Judicial

• In administrative programs, MVD’s revoke licenses of arrested and/or convicted DWI offenders but allow them to drive legally while revoked if they install interlocks.

• In judicial programs, judges mandate that convicted offenders install interlocks as a condition of probation.

• Some states have both in series (e.g. Florida) or parallel (e.g. New Mexico).


Basic Administrative Program1. An Interlock Licensing Law that makes an

interlock license available to anyone revoked for DWI who installs an interlock

2. Permits driving anywhere anytime in a vehicle with a functioning interlock

3. License Fee offsets MVD costs


Problems

1. Only 10-20% will install. The worst offenders will not.2. Most offenders will choose revocation over interlock.3. HOOPS: Pre-Interlock requirements will further

reduce compliance.4. There will be little overall reduction in drunk driving.

Enhanced Administrative Program 1. Compliance Based Removal; eg 6 months and 5000

miles of no recorded BAC’s > 0.04%2. Required for reinstatement of unlimited license3. Vehicle Forfeiture for driving while revoked without

an interlock.4. No Hoops (pre-interlock requirements)


Problems1. It still is a voluntary program.2. Most offenders will choose to drive without a license.3. There is a low probability of apprehension for DWR.4. The worst offenders will not be interlocked.5. Result: many unlicensed and uninsured bad drivers

Basic Judicial Program • Option for Judge to mandate an Interlock

sanction as a condition of probation.


Problems1. Many judges will not mandate an interlock2. Many offenders will plea away interlock sanction3. Many offenders will just not comply. 4. Offenders will claim “not driving” or “no car”.5. Those who need it most will not be interlocked.6. Result: many unlicensed and uninsured bad drivers

Enhanced Judicial Program 1. Mandatory Judicial Interlock sanction as a condition of probation 2. Require report to court of installation within 2 weeks3. One year for 1st, 2 yrs for 2nd, 3 yrs for 3rd, Lifetime for 4th. 4. Compliance Based Removal: with carrots and sticks5. Home Photo Breathalyzer for those who claim “no car” or “not

driving” (Alcohol-free breath twice per day)6. Offender financed indigent fund with objective standards


Problems1. Such a program does not yet fully exist.2. Requires some administrative components3. Often monitoring reduces cost-effectiveness4. Possibility of pleas from DWI to careless or reckless

Add On’s1. Focus probation resources on those who do not install IID’s2. Criminal sanction for attempts to circumvent interlock3. IID probation review every six months4. Triage of sanctions for those who are not compliant. 5. No pleas from DWI to careless or reckless driving6. Interlock as a condition of bond


Suggested Triage for Non-Compliance

1. Photo Interlock2. Require morning and evening breath tests3. Screening and Treatment if indicated4. Continuous Alcohol Monitoring (eg SCRAM or TAC)5. DWI Court

Best Practice Recommendation1. Combine previous four program in PARALLEL2. Include “ADD ON’s” and Triage as funds permit3. Focus probation and MVD resources on those who do not

install.4. Let the interlock sanction tests that are above set-point.5. Collect monthly reports, but only monitor circumvention.


Collect data for research on effectiveness.1. DWI arrests and convictions2. license revocations and interlock licenses.3. Interlocks installed and removed 4. A-I crashes, injuries, fatalities.

VI. Myths About First Offenders

1. First Offenders Drove Drunk Once2. Are Not Alcohol Abusers or Alcoholics3. Are a Negligible Part of the DWI Problem4. Are Less Likely to be Re-Arrested5. Are Not Responsible for Most DWI Fatalities6. √ Interlocks are not cost-effective for them7. √ Interlocks are a not a fair sanction for them8. √ Interlocks are not effective for them9. √ Interlocks are too lenient. Revoke them10. Sanctions are more important than preventionRoth 4/14/13 2013 Lifesavers Conference

They have driven an average of 500 times after drinking before their first arrest.

Evidence of Cost-Effectiveness

• Cost of interlocks is less than one third of the savings in the economic impact of the drunk driving crashes prevented. Benefit/Cost ~3.

• National Research that takes into account benefits other than DWI crashes shows an even greater Benefit to Cost Ratio.

• In a survey of 1513 Interlocked offenders, 70% agree or strongly agree that The

benefits of interlocks outweigh the costs. Roth 4/14/13 2013 Lifesavers Conference 72

Evidence of Fairness

Anonymous Survey of 15,641 Convicted Offenders while waiting for Victim Impact Panels to start: 81% responded Yes to the question: “Do you think that interlocks are a fair sanction for DWI?



Where Should We Focus our Sanctions?

In the past we have focused on Subsequent Offenders.

Subsequent Offenders have a slightly higher re-arrest rate.

Many more First Offenders are re-arrested than Subsequent Offenders because there

are more First Offenders.

Now we are Focusing on First Offenders

recovered with 1. contract of interlock installation, 2. successful administrative appeal or 3. Judicial dismissal.)

• Federal Grants for “Enforcing all-offender Interlock Law.” Define Enforcing as >50% inst.
