3. Interlock Laws
States are encouraged to increase the efficiency and effectiveness of their interlock programs.
All states including the District of Columbia have some form of interlock law that includes either judicial discretion or an administrative requirement or a hybrid of the two.

4. Interlock Laws
There have been several interlock law changes over the past few years.
In 2014, Alabama, Mississippi, and Missouri passed a law requiring all DWI offenders to install an interlock.
In 2014 Indiana also passed legislation requiring ignition interlocks for repeat offenders, and to allow a judge to order interlocks for first-time offenders.

5. Interlock Laws
In 2014 South Carolina passed Emma’s Law, which requires all high-BAC (0.15) offenders to install an interlock.
In 2015, Delaware, and Texas passed an all DWI offender law requiring an interlock.
Effective 7/1/2015, CT requires an interlock for drinking and driving arrests, including Administrative Per Se. Prior to 7/1/2015 the requirement was upon convictions.

6. Interlock Laws
In 2015 Kentucky strengthened its ignition interlock law which required an interlock for repeat offenders, high-BAC (0.15) 1st offenders and offenders who refuse a chemical alcohol test.
In 2016, Vermont and Washington D.C. passed an all offender interlock law, and Maryland passed “Noah’s law” an all offender law with a five-star rating from MADD (MADD 2017).

7. Interlock Laws
As of February 2017, 28 states and 4 California counties require all alcohol-impaired driving offenders to install an interlock.
11 states require interlocks for offenders with a high blood alcohol concentration (BAC) (usually or higher) and for repeat offenders.

8. Interlock Laws 6 states require devices only for repeat offenders.
1 state (NV) require devices for high-BAC offenders.
4 states do not have mandatory interlock requirements.

11. National Interlock Survey 2016
All 50 states and 11 manufacturers were contacted in September 2016 to request arrest and conviction data and relevant interlock data.
Counts of total installed ignition interlocks during a period of 1 year (12 months) in 2015, and total installed ignition interlocks in 2016 (January 1st to August 31st, 2016) were requested.

12. National Interlock Survey 2016: Definitions
Total installed number (TIN): the number of new ignition interlock device installations reported over a period of time.
Active installed number (AIN): the number of ignition interlock devices reported to be installed in a vehicle on the date designated by this request (i.e., a snapshot in time).

13. National Interlock Survey 2016: Data Request
States were also requested to provide, if possible, data according to offense categories.
Offense categories were defined as:
1st offender "basic" DWI;
1st offender high-BAC DWI;
refused test DWI and;
repeat DWI (2nd and subsequent DWI).

14. National Interlock Survey 2016: State Arrest Data
DWI arrest data were requested to estimate the number of potentially eligible offenders in each state.
18 states were able to provide total DWI arrest data for the reporting period from January 1st, to December 31st, 2016.
11 of these states were able to provide further breakdowns of arrest data by offense categories.
Arrest data may be used to make comparisons across states and to identify yearly increases or decreases. Last year 15 states provided data, 10 were able to provide breakdown of offense categories.
Reporting DWI arrests by offense category identifies the incidence of arrests in relation to each DWI offense category within a state.
Arrest information can be helpful to inform DWI enforcement and awareness campaigns.

15. National Interlock Survey 2016: State Arrest Data
13 states were able to provide total DWI arrest data for the reporting period from Jan. 1st to August 31st, 2016.
9 of these states were able to provide further breakdowns of arrest data by offense categories.

16. National Interlock Survey 2016: State Conviction Data
DWI conviction data were requested to further identify the potential number of eligible offenders in each state.
21 states were able to provide total DWI conviction data for January 1st to December 31st,
13 of these states further reported breakdowns of conviction data by offense categories.
Conviction data may be used to make comparisons across states and to identify yearly conviction increases or decreases. 16/9
Conviction data compared to arrest data is used to identify the those arrested for a DWI who are convicted. Conviction information can inform the planning of state DWI awareness and enforcement campaigns.

17. National Interlock Survey 2016: State Conviction Data
16 states were able to provide total DWI conviction data for January 1st to August 31st,
12 of these states were able to further breakdown conviction data by offense categories. Illinois was able to report all repeat offender DWI convictions (all 2nd and subsequent offenders).

25. National Interlock Survey 2016: Offender Eligibility
Percentage of offenders who installed among those who were eligible or required.
Dependent upon legislation, eligible offenders may include:
those arrested for a DWI (ALR requirement) or;
offenders convicted of a DWI (which is dependent upon offense categories that require an interlock).
This assumes that offenders are not deemed ineligible for other driving or non-driving violations unrelated to DWI.

40. National Interlock Survey 2016: discussion
Barriers that can impede states ability to provide data:
data capture processes vary by agency & jurisdictions;
states lack centralized or standardized data collection;
linkages between court data and DMV data are limited;
several states do not have the resources.

41. National Interlock Survey 2016: discussion
Few states could provide data other than TIN & AIN.
Several states could provide data within the project timeframe (6 months).
Few states could provide a breakdown by offense category.
Accurate records and timely reporting are essential to successful interlock programs (Casanova Powell et al. 2015).
