Interventions and Outcome Measures

Arms

active comparator: Active Control: Online Vehicle and Driver Safety Education

Participants in this arm will receive care as usual, and also complete an online video training module on vehicle and driver safety, with a short quiz at the end to determine compliance. The training content will not teach driving skills, as in the other online driver training arm. It requires up to two hours to complete and can be done from any internet-connected computer (at home, at school, etc.).

experimental: Online Driver Skills Training

Participants in the Online Driver Skills Training arm will complete an online driver skill training program known as Accelerated Curriculum to Create Effective Learning (ACCEL) for novice drivers. It requires up to two hours to complete and can be done from any internet-connected computer (at home, at school, etc.).

experimental: Behind-the-Wheel Driver Training

Participants in the Behind-the-Wheel training arm will receive professional behind-the-wheel training course delivered in-person on the road by a local driving school instructor through our partnership with a local driving school Coastline Academy or licensed driver training schools subcontracted by Coastline Academy.

Interventions

Online Vehicle and Driver Safety Education

This online video education program provides education in vehicle and driver safety (e.g. vehicle maintenance, adjusting car seats and seatbelts). This online training will take up to 2 hours to complete and will have a short quiz at the end to determine compliance with this online training.

Online Driver Skills Training

The online driver training is the Accelerated Curriculum to Create Effective Learning (ACCEL) is designed to enhance the ability to anticipate, recognize and respond to hazards and to maintain attention to the road. The training is delivered online via a computer and can be done from home or at a school or other site that has a computer with internet access. It requires up to two hours to complete, and will be hosted on a platform that will track progress and completion through the training (such as accuracy, duration in modules, time to complete) and a short quiz will be provided at the end to assess learning.

Behind-the-Wheel Driver Training

The professional behind-the-wheel training course will be conducted in-person, delivered by local driving school partner Coastline Academy or licensed driver training schools subcontracted by Coastline Academy. The curriculum consists of 6 hours of training with assigned practice between lessons, and meets Pennsylvania and national standards. Post-lesson forms completed by the instructors will record adherence and consistency (intervention fidelity).

Primary outcome measure

  • Hard Braking Events [ Time Frame: Measured over the 6 months post-licensure at the end of the study (about month 18-24), assessed at 2 and 6 months post-licensure, with primary outcome at 2 months post-licensure. ]
  • Pass rate on the licensure exam [ Time Frame: Measured at the time of the license examination, post-intervention (in about month 8-18). ]
