Prevalence of and Factors Associated with Driving a Vehicle with Timed-Out Inspection Certificate in Spain Martín de los Reyes, Luis Miguel Martínez Ruiz, Virginia Ana Rivera Izquierdo, Mario Jiménez Mejías, Eladio Lardelli Claret, Pablo Periodic vehicle inspection Timed-out certificate Cross-sectional Risk factors We wish to thank the Spanish Traffic Directorate (Dirección General de Tráfico) for allowing access to their database of traffic accidents with victims, and K. Shashok for editing the use of English in the manuscript. This study aimed to estimate the prevalence of vehicles on the road with a timed-out vehicle inspection certificate (TOVIC) and the associations of driver, vehicle, and environmental factors with this infraction. A quasi-induced exposure approach was used in this cross-sectional study to analyze a case series comprising 51,305 drivers passively involved in clean collisions (only one infractor driver involved) between two or more vehicles registered in the Spanish National Register of Road Crashes with Victims from 2014 to 2017. The prevalence of TOVIC was estimated in the whole sample and in subgroups defined by the variables considered. Multivariate logistic regression modeling was used to obtain adjusted odds ratios for the association between TOVIC and each category of the variables. The prevalence of TOVIC was low, although significant differences were found for certain subcategories of drivers, vehicles, and environmental factors. Significant positive adjusted associations were found between TOVIC and license-related infractions, vans (compared to cars), vehicle age, and vehicle defects. Several vehicle-related factors potentially associated with a high risk of involvement in a crash were clearly related with TOVIC, which suggests the need for measures to control this non-negligible number of high-risk vehicles on the road. 2022-02-23T11:49:30Z 2022-02-23T11:49:30Z 2021-12-23 info:eu-repo/semantics/article Martín-de los Reyes, L.M...
