Washington State Driving Intervention Research Study

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical trial is to test the effect of hazard perception training and testing on driving performance. Participants will be randomized into a treatment group receiving hazard perception training and a control group receiving a vehicle maintenance training. Researchers will compare the treatment and control groups to see if there are differences in driving behavior and crash rates.

Detailed Description
-----------------
The experiment's purpose is to assess the performance of the investigator's novel Driving Hazard Perception training intervention on improving hazard perception related driving skills, performance in driving exams, and long-term benefits as assessed by crash statistics and naturalistic driving behavior. A two-group pre-post experimental design will be used to evaluate the effectiveness of the new Driving Hazard Perception Training. Participants beginning a driver education program will be recruited. Once enrolled in the study, participants will be randomized to a treatment or placebo group. Baseline hazard perception assessment will be performed first, and then treatment group participants will receive hazard perception training. Lastly, both groups will take a hazard perception exam to assess the participants performance. All participants will use a smartphone application to collect driving data during the learner driver period and 12 months of independent driving. Driving behaviors and state level crash data will also be used to assess the impact of the Driving Hazard Perception Training.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Hazard Perception Training<br> | Behavioral: Hazard Perception Training<br>* The hazard perception training is comprised of six modules-three covering hazard perception and the remaining three covering attention maintenance. Each module is comprised of four scenarios. Each hazard perception scenario has two activities, while each of the attention maintenance modules have one activity per scenario. Altogether, there are 36 activities across the six modules. The entire training is expected to take approximately an hour to complete. All participants assigned to the treatment group will complete this training.<br>|
| Placebo Comparator: Vehicle Maintenance Training<br> | Behavioral: Vehicle Maintenance Training<br>* For participants randomized into the placebo group, they will receive a brief training on vehicle maintenance using the REDCap platform. This will consist of two short videos (one that is approximately 7 minutes long and a second that is approximately 12 minutes long). These videos describe regular checks that drivers should do, such as checking windshield wiper fluid levels, and how to change engine oil. Following each video, several multiple-choice knowledge check questions will be given to participants.<br>|
