Impaired driving remains a major traffic safety challenge in the United States. While public awareness campaigns and law enforcement efforts have long been used to discourage driving under the influence of alcohol or drugs, an important question remains: Which strategies actually influence people’s intentions and behaviors?
A recent study presented at the International Conference on Transportation and Development 2025 examined public perceptions of impaired driving interventions and identified the factors most closely associated with a willingness to change behavior. Researchers surveyed 876 respondents about their experiences, concerns, and views on educational and enforcement strategies.
Education Matters Most
One of the study’s most important findings was that the perceived effectiveness of educational campaigns was the strongest predictor of a respondent’s likelihood to change behavior related to impaired driving. Individuals who believed awareness campaigns were effective were significantly more likely to report that those campaigns could influence their decisions.
This suggests that well-designed educational efforts do more than simply share information. Effective campaigns can shape attitudes, increase risk awareness, and encourage safer transportation choices before someone gets behind the wheel.
Community Concerns Drive Action
The research also found that concern about impaired driving within one’s community was strongly associated with a greater likelihood of behavior change. When people viewed impaired driving as a local issue affecting their neighborhoods, they were more receptive to prevention messages and interventions.
This finding highlights the value of community-based approaches that personalize the consequences of impaired driving rather than presenting it as a distant or abstract problem.

Enforcement Still Plays a Critical Role
- Educational campaigns may have emerged as the strongest predictor, but enforcement remains an essential part of the solution. Respondents who viewed high-visibility enforcement practices as effective were also more likely to indicate they would change their behavior. Awareness of legal penalties showed a similar positive effect.
The results reinforce previous research showing that visible enforcement can serve as a powerful deterrent. When drivers believe that impaired driving laws are actively enforced, they may be less willing to take the risk.
Public Support for a Balanced Approach
Researchers analyzed open-ended survey responses and found that participants frequently mentioned both education and enforcement when discussing solutions. Respondents emphasized the importance of awareness campaigns, stronger law enforcement, designated drivers, ride-sharing services, and community involvement.
These responses suggest that the public does not view prevention as an either-or choice. Instead, people recognize that reducing impaired driving requires a combination of strategies working together.

Moving Forward
Based on these findings, the researchers recommend an integrated approach that combines:
- Evidence-based educational campaigns
- High-visibility enforcement efforts
- Community engagement initiatives
- Infrastructure improvements, including designated ride-share locations and safer transportation options
As impaired driving continues to evolve, particularly with growing concerns about drug-impaired driving, transportation safety professionals and policymakers should focus on strategies that increase awareness while maintaining a strong and visible enforcement presence.
The study’s message is clear: education and enforcement are most effective when they work together. By combining these approaches and addressing community concerns, agencies can create more meaningful and lasting reductions in impaired driving.
