New study tests online tool to curb impaired driving in young adults
NCT ID NCT07368894
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether adding a brief online personalized feedback program to standard screening and counseling can reduce impaired driving in young adults aged 18-30. Researchers will enroll 600 participants in Washington State who have already received standard screening. Half will get the extra online program, and the other half will not. The main goal is to see if the program lowers the number of times people drive while impaired by both alcohol and cannabis over three months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- Personalized feedback intervention (online behavioral program)
- What this could lead to
- If successful, this could point toward a simple, scalable way to reduce impaired driving among young adults.
- What could go wrong
- This is an early-stage study with no treatment for a disease; it only measures behavior change. Results may not apply outside Washington State or to other age groups.
