- General versus Specific Effects
35Significant Risk Factors in Alcohol-Related
Fatal Crashes
- Alcohol Consumption Among Youth
- Problem Drinking/Binge Drinking/Beer
- Males
- Age (16-34)
- Most Victims are in the DWIs Vehicle
- Most DWIs have no Prior A/R Arrest
- Late Night/Early Morning/Weekend Problem
- Low Seat Belt Use (as low as 15-20)
36Alcohol Impaired DrivingCountermeasures
37Major Approaches
- Prevention
- Intervention
- Deterrence
- Rehabilitation
- Technology
38Prevention
- Mass Media
- Alcohol Education
- Alcohol Policy
39Mass Media An Essential Component of Any Program
- Legislation
- requires public awareness
- Enforcement
- requires public awareness
- Sanctions
- require public awareness
- Incentives
- require public awareness
40Mass Media
- Much potential for general impact
- Weak to moderate number of studies
- Recent CDC review suggests 13 effect
- Contributes to impact of other programs
- Agenda setting potential
- Public Service vs. Earned vs. Paid
41Mass Media
- Brief, intense campaigns (most effective?)
- Multi-year, planned efforts
- High saturation, paid media, television
- Targeted messaging?
- Support for other, more effective, measures
appears to be most effective
42Alcohol Education
- Major obstacles to population-wide impact
- Education, normative, peer, resistance
- Evidence of self-reported impact on DD/RDD in
classroom and on campus - No evidence of crash reduction impact
- One of the best studies here in Michigan
43Alcohol Policy
- Alcohol Advertising and Marketing
- Alcohol Availability
- Physical, Economic, Social, Subjective
- Minimum Drinking Age Laws
44Alcohol Policy
- Strong potential for population-wide effect
- Some programs have shown impact (MDA)
- Consistent Findings that advertising and
availability can affect consumption, but .. - Little evidence of impact to date (likely due to
less than full implementation)
45Intervention
- Ride Service
- Designated Drivers
- Server Training
- Server Liability
- Enforcing ABC Laws
46Ride Service
- Weak research base
- One example of community-wide impact
- Capable of creating general deterrence?
- Important part of a comprehensive community
program - Media likely essential for impact
47Designated Driver
- Very weak research base CDC review
- Not likely to create general effect more likely
to be a response to deterrence - Major obstacle lack of use by high risk
- Some concern about increased drinking
- Another component of a comprehensive community
program - Media likely essential for impact
48Responsible Beverage Service (RBS)
- Three Elements of RBS
- Server Training
- Management Policy
- ABC Enforcement
- Server Liability may be an essential factor
(i.e. RBS likely to be a response to deterrence)
49Responsible Beverage ServiceServer Training
Component
- Moderate research base
- Potential for population-wide impact
- Major obstacle management disinterest
- Relatively consistent findings of server change
- Need carrot and stick incentives
- Server Liability
- ABC Enforcement
50Responsible Beverage ServiceManagement Policy
Component
- Weak research base
- Potential for population-wide impact
- Major obstacle management disinterest
- Need more research on policies (e.g. happy hours,
cut off of serving at specified times, etc.) - Need carrot and stick incentives
- Server Liability
- ABC Enforcement
51Responsible Beverage ServiceABC Enforcement
Component
- Weak research base
- Potential for population-wide impact
- Major obstacle is lack of resources
- Some evidence of Impact
- Stings or Decoy Programs
- Cops in Shops
52Server LiabilityDram Shop Laws/Model Law
- Weak research base
- Strong Potential for general impact
- Some evidence of Impact (e.g. Texas)
- Incentives for Responsible Alcohol Service
53Deterrence(Traffic Law System)
- Legislation
- Enforcement
- Sanctions
- Fines
- License
- Vehicle
- Jail
- Interlocks
54Laws That Have Shown Impact
- Illegal Per Se
- Administrative License Revocation (ALR)
- Minimum Drinking Age (MDA)
- .08 Illegal Per Se
- Zero Tolerance for Youth
- Vehicle Sanctions
- Primary Seat Belt Laws (Michigan)
55Enforcement
- Strong research base consistent
- Checkpoints are most effective (-20)
- Obstacles among officers and management
- Saturation patrols and regular patrols are also
effective - Intensive media is an essential component
- Major obstacle competing priorities
56License Sanctions
- Strong research base very consistent
- General and Specific Effect
- Most effective of any sanction/in spite of DWS
- DWS erodes general deterrence impact although
specific deterrence remains high - Intensive media is an essential component
- Administrative application has shown most effect
57Vehicle Sanctionsfor repeat DWI or Driving
While Suspended (DWS)
- Moderate research base consistent results
- Strong specific effect potential for general
- Works better for repeat offenders than 1st off.
- Can be used to counter DWS and to deal with
repeat offenders - Intensive media is an essential component
- Administrative application is needed
58Jail
- Moderate research base inconsistent results
- Possible specific effect for 1st offenders
- Some studies show detrimental effect
- Much potential for general effect
- Generally used for leverage/ last resort
- May work best in special facilities w/treat.
- Costly
59Alcohol Safety Interlocks
- Moderate research base consistent results
- Strong specific effect (as much as -65)
- Effect appears limited to period of use
- No demonstrated potential for general impact
- May counter DWS often used to deal with repeat
offenders - Can work well with treatment
60Alternatives to Jail(e.g., In-home detention,
Intense Probation, Custom Sentencing)
- Weak research base but consistent results
- Specific effect most likely to be demonstrated
- Potential for general effect (but universal
application is unlikely via courts) - Generally leveraged by threat of jail
- Many approaches complement treatment
- Potential for affecting hard core, repeat
offender
61Education and Treatment
- Strong research base relatively consistent
results - Some specific effect demonstrated (8-9)
- Less potential for general effect (but should be
part of a comprehensive, balanced program) - Often used in lieu of jail should not be used in
lieu of license sanction (add to license effect) - Perhaps most appropriate for hard core, repeat
offender, but major behavior change unlikely.
62What Has Worked Worldwide?Transportation
Research Board (TRB) Review
- Programs of the 1980s
- Activism
- Legislation
- Enforcement
- Sanctions
- Public Information
- Result Has Been A Change in the Norm!
- (Programs of the 1990s Remain Less Clear)
63Results of CDC Systematic Review
- .08 BAC Laws (7 effect)
- Zero Tolerance Laws (17 effect)
- MLDA Laws 16 effect
- Checkpoints (18 to 21 effect)
- Server Training Programs some impact?
- Mass Media Programs (13 effect)?
- Designated Driver Insufficient Evidence?
- School-Based Education effect on RDD?
64DeterrenceDoes It Work Only for the Least
Severe Offenders?
- There is Evidence to the Contrary
65Youth A/R Fatalities1989-1999
66High BAC Fatalities1989-1999
67Where Are We Now?
- Progress Has Clearly Leveled Off
- Awareness and Concern Has Declined
- Enforcement Has Declined Significantly
- Youth Laws Not Being Enforced
- Many Laws Being Eroded
- Seat Belt Use Among A/R Drivers Low
- Other Priorities
- (not much has changed in several years)
68Problems With the SystemHedlund and McCartt
(2001)
- Failure to detect, arrest, convict, sanction,
monitor - DWI laws are complicated inconsistencies
- Arrest rates have been declining
- Arrest procedures time-consuming/complicated
- Plea bargains and diversions
- Sanctions not applied (swiftly or certainly)
- Do not identify repeat offenders
- Do not monitor offenders in the system
- Poor data and records systems
- Inadequate resources
69What Will Likely Work in the Future?
- Enforcing DUI Laws
- Enforcing MDA and ZT laws for Youth
- Alcohol Control and Serving Policies
- Graduated Sanctioning Systems
- Graduated Licensing and Vehicle Sanctions
- Primary Seat Belt Laws
- Technology?
- Fixing the Traffic Law System Components
70Increasing Safety Belt Use
71Increasing Safety Belt UseApproaches Used
- Education
- Incentives
- Mass Media/Public Information
- Legislation
- Enforcement
- Penalties
72Education Programs
- Very little evidence of impact to date
- Early programs increased usage by very small
amounts little evidence of sustained impact - No evidence of impact on usage among crash
victims - Even if impact were documented, it would likely
only affect those persons exposed

74Evaluation of Beltman Education Programin
Missouri (target group 500) (Missouri Office
of Highway Safety, 1981)
75Incentive Programs
- Some evidence of impact at low use rates
- Early programs increased usage by modest amounts
but there is little evidence that such impact
remained over time - No evidence of impact on usage among crash
victims - Somewhat broader impact potential than education
programs

Chapel Hill, NC (Campbell et al., 1982)
77Incentive/Education/Policy ProgramU.S.D.O.T.
Headquarters, Washington, DC
78Mass Media
- Potential for population-wide impact
- Little evidence of impact (when use alone) even
at very low usage rates - Recent consistent evidence of impact in
conjunction with enforcement efforts - Click it or Ticket programs
- Paid media efforts have been shown to result in
major increases in awareness
79How Effective is Mass Media By Itself?
- Perhaps the most frequently implemented
countermeasure since the 1960s - Not nearly as much documented research as for
legislation and enforcement - Much of the available research was conducted when
usage rates were very low (which is also when
programs are likely to be most effective) - BUT there is some evidence of potential

Southeast Michigan(Motorists Information Inc.,
1978)
82Study of High vs. Low Use CommunitiesThree
Activities Associated with High Use(Burkhart et
al., 1987)
- Tailored Media
- Greater Market Penetration
- Higher Enforcement Levels
83Conclusions Regarding Effect of U.S. Mass Media
Programs to increase Seat Belt Use
- All studies were conducted in pre-law situations
when baseline use rates were very low - Although some media programs were of high
quality, the studies were of moderate quality. - Very little evidence of impact greatest evidence
comes from MII study which showed a 4.4 pct. pt
increase from a 12 baseline rate. - This result is not all that different from foreign
84Summary of Research on Effectiveness of Mass
Media to Increase Seat Belt Use
- Foreign (multi-year) studies showed 10-20 point
increases from low baselines (average of 4-5 pts
per campaign) - U.S. studies also found 4-5 percentage point
gains from similar pre-law, low use baselines - Community programs show some impact
- High vs. Low Use Communities
- Model Communities
- CDC review of mass media programs to reduce
impaired-driving suggest impact of mass media in
the context of other prevention efforts (Elder et
al., in process).
85Mass Media An Essential Component of Any Program
- Legislation
- requires public awareness
- Enforcement
- requires public awareness
- Sanctions
- require public awareness
- Incentives
- require public awareness
86Legislation/Penalties
- Safety Belt Laws Have Been Effective
- Increased U.S. Use from lt15 to nearly 50
- Primary Laws Have Been Most Effective
- Generally Result in 10-15 point increase
- Fines Make a Difference
- Much Weaker Research Base
- Points Would Likely Make a Difference
- Still Less Weaker Research Base

94Summary of Effect of Laws
- Initial Seat Belt Laws Gained Average of 30 pts
- Primary Law upgrades have gained an average of
12-14 points (over pre-existing 2nd law levels) - Although some decay results without follow-up,
all states have continued to show increases with
continued enforcement - Intensive media is an essential component of both
the law and enforcement interventions
95Enforcement
- As with DWI, there is strong consistent evidence
of impact - Checkpoints have been most effective as have
highly visible waves of enforcement - Saturation patrols and regular patrols can also
be effective - Intensive media is an essential component
- Major obstacle in competing priorities
- Enforcement Zones are providing new energy

100SummaryImpact of (Highly Visible) Enforcement
Efforts
- Capable of immediate gains in safety belt use
- Require intense media efforts
- Enhance impact of laws (secondary and primary)
- Must be periodically repeated (ratchet effect).
- Responsible for recent gains in U.S. (and in
Mich.) - Typical gains are 8-16 percentage points
- Require full implementation to be effective
101Safety Belt Use and Alcohol-Impaired Driving
- Can they be Linked?
- Should they be Linked?

105Seat Belt Use Rates in a Region V StateA
Comparison of Various Groups
106Summary
- Most important need is to create new energy and
focus on these issues. - Many combinations of efforts are likely to work,
given sufficient effort - Enforcement is an essential component
- Swift and certain sanctions are effective
(especially with impaired driving) - Media will be key to future success.
107Summary (continued)
- Impaired driving efforts may wish to start with
the seat belt model and expand - Make Use of Special Tools for Youth
- Progressive Sanctions for Repeat Offenders
(particularly impaired drivers) - Integrate DUI and Seat Belt Efforts?
- New enforcement approaches for safety belts may
help impaired driving as well.
