... Truck safety research has focused on issues as diverse as environmental conditions of the roadway, weather, and traffic density (Corsi, Fanara, & Roberts, 1984); maintenance, age, and ergonomics of the vehicle, and the fatigue, inattention, and age/experience of the driver (Campbell, 1991;Cantor, Corsi, Grimm, & Ozpolat, 2010;Crum & Morrow, 2002;Stutts & Hunter, 2003), driver attitudes, and driver safety behaviors (Douglas & Swartz, 2016a;Kim & Yamashita, 2007;Lueck & Murray, 2011;Swartz & Douglas, 2009), carrier safety management (Corsi, Fanara, & Jarrell, 1988;Mejza, Barnard, Corsi, & Keane, 2003;Mejza & Corsi, 1999;Morrow & Crum, 2004), safety climate (Huang et al., 2013;Zohar, Huang, Lee, & Robertson, 2014), safety technology adoption (Cantor, Corsi, & Grimm, 2006Cantor, Corsi, Grimm, & Singh, 2016), and the impact of driver turnover (Miller, Saldanha, Rungtusanatham, & Knemeyer, 2017). Contextual factors such as carrier size and financial performance as a contributor to safety performance (Bruning, 1989;Cantor et al., 2016;Miller & Saldanha, 2016), and the effect of motor-carrier industry segment (e.g., general freight vs. private; short haul vs. long haul) on environmental exposure to risk and safety performance (Moses & Savage, 1996), have also been identified as important considerations. Theoretical models suggest that the subsystem of driver and vehicle interacts with the environment, resulting in judgments and decisions, behaviors, and outcomes. ...
