Washington State Driving Intervention Research Study

NCT06146634 | Active Not Recruiting

• 1 other identifier: IRB00025991
• Study Type: interventional
• Target: 8,000
• Locations: 1 country
• Sites: 1

Brief Summary

The goal of this clinical trial is to test the effect of hazard perception and attention maintenance training and testing on driving performance. Participants will be randomized into a treatment group receiving hazard perception or attention maintenance training or a control group receiving either vehicle maintenance training or the status quo ZED training. Randomization will occur by location. Researchers will compare the treatment and control groups to see if there are differences in driving behavior and crash rates.

Interventions

Hazard Perception Training BEHAVIORAL

The hazard perception training is comprised of three modules. Each module is comprised of four scenarios. Each hazard perception scenario has two activities. The entire training is expected to take approximately an hour to complete.

Hazard Perception Training

Vehicle Maintenance Training BEHAVIORAL

For participants randomized into the placebo group, they will receive a brief training on vehicle maintenance using a series of short videos. These videos describe regular checks that drivers should do, such as checking windshield wiper fluid levels, and how to change engine oil. Altogether the videos will last approximately 1 hour.

Vehicle Maintenance Training

Attention Maintenance Training BEHAVIORAL

The attention maintenance training is comprised of three modules. Each module is comprised of four scenarios, with each scenario corresponding to one activity. The entire training is expected to take approximately an hour to complete.

Attention Maintenance Training
