A MESSAGE FROM RHONDA FAUGHT, SECRETARYNew Mexico Department of Transportation

The goal of the New Mexico Department of Transportation is to reduce trafficrelated fatalities, injuries and crashes. Traffic crashes are the leading cause ofinjury and death for all New Mexicans between the ages of one and forty-four,and Driving Whlie Impaired (DWI) is a major cause of severe crashes. TheDepartment addresses this problem, in part, by developing a State HighwaySafety and Performance Plan and obtaining federal funds as authorized underthe Transportation Equity Act for the 21st Century (TEA 21).

During the past 22 years, DWI deaths have decreased by 47 percent. Research on drunken drivingfatalities at the national and local levels suggests state and local prevention measures have had aneffective impact on injury and fatality rates. This report, “Driving While Impaired,” produced forthe Department by the University of New Mexico, Division of Government Research, providesstatistics that may be used to understand motor vehicle crashes due to alcohol and other relatedfactors. It is our intent to produce a report for our safety partners to use as a tool to implement andcontinue programs that help prevent and reduce traffic-related injuries and fatalities.

National, state and local collaboration efforts have made great strides in the fight against drivingwhile impaired. The Governor’s DWI Multi-agency Plan provides for a statewide comprehensiveand cohesive approach to the problem. Our partners, other state and local government agencies,non-profit organizations, legislators, and law enforcement agencies statewide deserve recognition forsuccessful traffic safety programs.

On the Cover:The cover photo shows Dr. Richard Roth, PhD, blowing into the ignition interlock which has been installed in his vehiclesince he became a citizen lobbyist in 1999. Dr. Roth wrote the first drafts and lobbied successfully for four interlock bills,which have become law in New Mexico. Ignition Interlocks require an alcohol-free breath sample from the driver before avehicle can be started. Also, random retests are required while the vehicle is being driven and all breath alcoholmeasurements are recorded in the interlock.

The Traffic Safety Bureau of the New Mexico Department of Transportation (NMDOT) develops programs toaddress traffic issues in the state. The mission of the Bureau is to continuously reduce traffic-related fatalities,injuries and crashes. Program initiatives include education, enforcement, regulation, legislation, prevention, screen-ing and treatment, and public information. The Bureau works in partnership with New Mexico law enforcementagencies statewide to enforce traffic safety laws.

Note: The 1999 crash file contains 15% fewer crashes than the 1998 file. This may be due to problems in implementing the new system after the old system failed, or to under-reporting. Care should be used when interpreting differences between 1999 and other years in this report.

♦ These are counts of all factors reported to have contributed to fatal crashes. These are not the same thingas fatal crash counts. A single crash often involves more than one vehicle, and each vehicle may be affectedby more than one factor. The percents shown are the percents of vehicles in fatal crashes which wereaffected by each of the contributing factors. For these reasons the total here is higher than in other tablespresenting fatal crash information, and the percentages sum to more than 100.

♦ In 2002 both New Mexico and National rates increased.

IMPACT

1 Sober people are drivers, passengers and pedestrians who were involved in a crash with a driver or pedestrian who had been drinking.

2 Impact is the cost of DWI related crashes in New Mexico based on Federal Highway Administration estimation formulae (The Costs of Highway Crashes, FHWA-RD-91-055, Federal Highway Administration, 1991). The figures are based on 1988 dollars, adjusted for inflation to 2002 dollars. These are estimates, not actual dollar amounts. Included are direct costs such as lost wages and medical expenses, and indirect "willingness to pay" estimates of lost quality of life.3 Population estimates are for July 2002, from the Bureau of Business and Economic Research, University of New Mexico.

LAWS

Note that this is not a criminal offense, and the resulting license revocation is an administrative, not acriminal penalty. Municipalities are prohibited from establishing per se BAC limits different from statelimits (§66-8-102.2). Licenses remain revoked until offenders reinstate them. First offenders whodid not refuse the BAC test may obtain limited licenses after a 30-day revocation.

DWI Penalties in New Mexico

1 Aggravated DWI is a conviction for DWI when the offender: (a) drove with a BAC (Blood Alcohol Concentration) of .16 or higher, (b) caused a person bodily injury while DWI, or (c) refused a BAC test when arrested.

2 Jail time must be served consecutively.3 The judge shall sentence the offender to alcohol screening; the court will approve screening

programs; the court does not have to order the offender to pay for it (§66-8-102K).4 Please note: Limited license: A limited license is restricted to driving to or from work or school or to attend

court-ordered treatment and is available only to first offenders who took the breath or blood alcohol test.Interlock license: After a 30 day revocation, an ignition interlock license is available to anyone who has hada DWI except for those who have killed someone while driving impaired. The penalty for driving without aninterlock is the same as driving while revoked. The interlock license requires drivers to install interlocks on allcars they drive. For a mail in application for either of these licenses go to http://ipl.unm.edu/traf/pubs/mvd10792.pdf or contact the Motor Vehicle Division nearest you.

♦ A deferred sentence on a first offense is still a first offense for the purposes of defining subsequent offenses(§66-8-102E).

WHERE

Sources: Crash files and Driver History file

1The crash percentages shown are the percent of all crashes which involved alcohol. For example, 46 percent of allBernalillo County fatal crashes involved alcohol, and resulted in 33 fatalities.

2Rates are per 1,000 licensed drivers. 3Severe crashes are those involving death or injury.

♦DWI convictions are those handed down in 2002. The citations which resulted in these convictions could have beenissued prior to 2002. See the note on page 15 for a complete explanation. Convictions are counted by county ofdriver residence, not the county in which the citation was issued. Driver residence county was determined by ZIPcode. The 642 convictions received by drivers with missing, invalid, or out-of-state ZIP codes are shown as “Other”and are included in the total.

1 This is the percentage of citations which were issued after a traffic crash brought the DWI incident to police attention.

2 Only citations for which a BAC was determined are included; citations for which the offender refused to submit to a BACtest are excluded.

3 These are citations issued in 2002 for results which were available by July 2003. The conviction counts differ from thosein other tables because these are based on citations issued in 2002 as opposed to convictions handed down in 2002. Theresulting convictions or dismissals could have been decided in 2003.

4 These are the average number of days from the date of the citation to the date of any court disposition as of July 2003. Forexample, the 3,166 convictions in Bernalillo County were decided an average of 125 days after the citation.

DWI Convictions Alcohol Crashes

REPEAT OFFENDERS

♦ There were 12,067 people convicted of DWI in 2002. Of those, 9,235 had not been convicted since1997, and 7,709 had not been convicted since 1970 (1,526 had been convicted at least once between 1970

and 1997). The number of repeat convictions (5,183, see chart on the page 14) is not equal to the totalminus the number of first convictions, because some people were convicted more than once in 2002. Only theirlastconviction is included in the table above, while all repeat convictions are included in the chart on the nextpage. (Please also note that the number of repeat convictions on the charts on page 14 and 16 differ due tomissing data.)

Conviction note: Unless otherwise noted, conviction counts in this report are based on convictions handeddown in 2002, and are only comparable to counts since the 1994 edition of this report. The citationswhich resulted in these convictions could have been issued before 2002. Due to the sometimes lengthy periodbetween the citation and conviction (see table on page 13), counting convictions resulting from citations issuedduring a particular year (e.g., 2002) would result in convictions after the publication of this report never beingcounted. By counting convictions regardless of citation date, all convictions are included.
