To conduct a pilot study to evaluate the predictive value of the Montreal Cognitive Assessment test (MoCA) and a brief test of multiple object tracking (MOT) relative to other tests of cognition and attention in identifying at-risk older drivers, and to determine which combination of tests provided the best overall prediction. ⋯ Although the best four-test combination was much better than a single test in identifying at-risk drivers, there is still much work to do in this field to establish test batteries that have both high sensitivity and specificity.

Observational Study
Observational study of child restraining practice on Norwegian high-speed roads: restraint misuse poses a major threat to child passenger safety.
Restraint misuse and other occupant safety errors are the major cause of fatal and, severe injuries among child passengers in motor vehicle collisions. The main objectives of the present, study were to provide estimates of restraining practice among children younger than 16 years, traveling on Norwegian high-speed roads, and to uncover the high-risk groups associated with, restraint misuse and other safety errors. ⋯ This study provides a detailed description of the characteristics of restraint misuse and, the occupant's exposure to unsecured objects. Future education and awareness campaigns should, focus on children aged <8 years. The main challenges are to ensure correct routing and tightness of, harness straps and seat belts, correct installation of child restraints, and avoidance of premature, graduation from child restraints to seat belts only. Information campaigns should also advocate the use, of chest clips and address the potential risks of hard, heavy objects in the passenger compartment and, the importance of the placement and strapping of heavy objects in the trunk.

Novice drivers are overrepresented in traffic collisions, especially in their first year of solo driving. It is widely accepted that some driving behaviours (such as speeding and thrill-seeking) increase risk in this group. Increasingly research is suggesting that attitudes and behavioural intentions held in the pre-driver and learning stage are important in determining later driver behaviour in solo driving. ⋯ A sample of 204 learner drivers completed a self-report questionnaire near the beginning of their learning, and then again shortly after they passed their practical driving test. Results showed that self-reported intentions regarding speed choice, perceptions regarding skill level, and intentions regarding thrill-seeking (through driving) became less safe over this time period, while self-reported intentions regarding following distance and overtaking tendency became safer. The results are discussed with reference to models of driver behaviour that focus on task difficulty; it is suggested that the manner in which behind-the-wheel experience relates to the risk measures of interest may be the key determining factor in how these change over the course of learning to drive.

Low seat belt use and higher crash rates contribute to persistence of motor vehicle crashes as the leading cause of teenage death. Service-learning has been identified as an important component of public health interventions to improve health behavior. ⋯ A high school service-learning intervention was associated with improved seat belt use regardless of race, ethnicity, or gender, but did not eliminate disparities adversely affecting minority youth. Continuous incorporation of service-learning in high school curricula could benefit quality improvement evaluations aimed at disparities elimination and might improve the safety behavior of emerging youth cohorts.

This study proposes a two-equation Bayesian modelling approach to simultaneously study cyclist injury occurrence and bicycle activity at signalized intersections as joint outcomes. This approach deals with the potential presence of endogeneity and unobserved heterogeneities and is used to identify factors associated with both cyclist injuries and volumes. Its application to identify high-risk corridors is also illustrated. ⋯ Corridors with high bicycle volumes, located mainly in the central neighbourhoods of Montreal, have lower risk of injury. These results may reflect the "safety in numbers" hypothesis or cyclist preference towards safer intersections and corridors. Despite these corridors having a lower individual risk, they are nevertheless associated with a greater number of injuries.
