In the US, teenage drivers have an increased risk of being involved in crashes. To address this, post-license advanced driving programs have emerged. This study gains teenagers’ perspective of a post-license defensive driving program focused on a hands-on introduction to emergency braking, skid recovery and the dangers of distracted driving. The teenagers completed a survey immediately following the program and a phone interview three months later. The open-ended survey and phone interview items reflect the program’s key concepts. During the follow-up phone interview, the majority of teenagers reported using the skills experienced and half of the participants who participated in the phone interview reported using skills that they learned to avoid a crash. Almost all teenagers reported anticipating or changing their driving behaviors, specifically by reducing distractions, having a heightened awareness and changing their driving position. The survey and follow-up phone interview results suggest that the teenagers benefited from the skills introduced and, from the teenagers’ perspective, has helped them avoid crashes.

In the US, teenage drivers have an increased risk of being involved in crashes. To address this, post-license advanced driving programs have emerged. This study gains parents’ perspectives while observing their teens’ involvement in a post-license driving program focused on a hands-on introduction to emergency braking, skid recovery and the dangers of distracted driving. Parents completed a survey after the program, and for comparison purposes, the teens also completed a survey at the end of the program. While the parents only observed the program, the results revealed that most learned useful information and would consider additional training for themselves. Almost all teens and parents reported anticipating changing their driving behaviors, specifically by reducing distractions, having a heightened awareness and changing their driving position. These results suggest that parents benefited from simply observing the class.

Rear-end crashes are one of the leading types of crashes today. The anti-lock braking system (ABS) was designed to assist drivers during emergency braking situations by preventing wheel lock up, allowing drivers to retain control of the vehicle. Not all drivers have knowledge and experience with ABS, especially the haptic brake pedal feedback produced by ABS. There studies introduce a new method to train ABS using an emergency braking task on a simulator and an interactive exercise, Pedals Emergency Stop©. The interactive exercise was designed to prompt participants to press the brake pedal in a motion that is consistent with emergency braking and experience haptic ABS feedback. Participants that depressed the brake pedal quickly to the maximum travel and held that pedal position “passed” the trial. In Study 1, participants (N = 63) completed 15 trials, where it took on average three trials to “pass” for the first time, and 85% of the participants experienced their first “pass” within the first four trials. There were no differences observed between participants with previous knowledge and experience feeling ABS versus those who did not have prior knowledge and experience with ABS. The participants in this study thought that they had enough trials, that the exercise was a practical tool, and recommended the task for new drivers and refresher training, as well as for evaluating fitness to drive. Suggested improvements included a practice followed by three tests, all with four trials each; passing criteria of three out of four trials; and modifications to the feedback presented immediately after completing each trail. Study 2 was conducted (N = 38) to investigate the proposed “passing” criteria, where 95% passed on Test 1. The results revealed that the criteria to pass was reasonable. Future research should examine how the Pedals Emergency Stop© interactive exercise generalizes to on-road driving.

Occupational therapists need objective tools to evaluate and provide interventions that promote the recovery and rehabilitation of clients. Driving, a common goal for clients after an injury or illness, is a complex task that relies on visual, cognitive, and motor skills. The Functional Object Detection and Functional Object Detection (FOD)—Advanced driving simulator scenarios were developed to provide objective and repeatable driving experiences allowing clinicians to assess their clients’ forward (focal) and peripheral vision, lane keeping, and speed maintenance, as well as provide interventions. Using FOD—Advanced, clinicians can adjust variables to create various task scenarios or combinations to meet the client’s needs and facilitate recovery by providing an appropriate challenge. This study examined four driving simulator scenario combinations and age-related differences for one combination. Study 1 explored older adults’ performance using four possible combinations of FOD—Advanced. Five out of eleven variables (average target reaction time, percentage of targets detected, average brake reaction time, number of target extra presses, and average speed) were effective in distinguishing among the four combinations of FOD with a cross-validated classification rate of 72%. In Study 2, one combination was selected from Study 1 and a group of teens completed the same tasks to evaluate age-related differences. Four out of thirteen simulator variables (standard deviation of brake reaction time, number of target extra presses, average target reaction time, and standard deviation of target reaction time) maximally distinguished the older adults from the younger participants with a cross-validated classification accuracy of 78%. Implications and recommendations for clinical practice and future research are provided.

Traffic-related crashes impact drivers of all ages. Post-license driving classes have emerged to equip drivers with higher level skills needed to prevent and avoid emergency situations. A performance driving center offers teenage and adult car control classes designed to address defensive driving skills through both classroom instruction and hands-on practice on a closed-road track. To obtain the views from teenagers and adults, both groups completed a survey immediately after their classes, and the adults completed a phone interview six months later. Results from the teenage and adult survey showed that both groups reported the most important topics learned during the car control class were skid recovery, using the antilock braking system (ABS) and looking where the car should go. Both teenagers and adults reported that they plan to significantly change their driving behaviors, especially those concerning seating, hand and mirror positions. Overall, after the class, the teenagers and adults felt “moderately competent” in their ability to perform the exercises practiced during the class, which increased from the rating of “not competent” prior to the class. The results from the phone interview with the adults suggest that ABS braking was the most important topic six months later. ABS braking was also the single-most reported skill used after the class and the self-identified skill most used to avoid a crash. The phone interview showed that the adults accurately predicted their use of the behaviors (seating position, vision, distractions, etc.) and turned those behaviors taught during the class into habits of their daily driving. Overall, the results from the teenage and adult survey, as well as the phone interview with the adults, suggest that the participants benefitted from the knowledge and skills gained from the one-day car control class.

Rear-end crashes are a common crash scenario, which contribute to many traffic related injuries and fatalities. A performance driving center offers adult car control classes focused on defensive driving skills, which include both classroom and behind-the-wheel instruction on a closed-road course. One focus of the class is activation of the anti-lock braking system (ABS), which was designed to help drivers during emergency braking situations. In the classroom, participants learn what ABS is as well as how and when it functions. On the closed-road course, participants learn how to activate ABS and how the system feels when it is activated. The goal of this study was to understand how knowledge of and experience with ABS prior to the class relates to a driver’s ability to activate ABS. The participants’ ability to activate ABS was evaluated by the driving instructor using a behaviorally anchored rating scale. Participants completed a survey before and after the class to gain knowledge of and experience with ABS. The results of the study showed that participants who previously knew what ABS felt like or had prior practice/training activating ABS performed significantly better activating ABS than those who simply knew what ABS means or had previously experienced ABS activation during their first of multiple attempts.
