Safety Benefits of Speed Limiters in Commercial Motor Vehicles Using Carrier-Collected Crash Data

Influence of Travelling Speed on the Risk of Injury Accident: a Matched Case-Control Study

“…In the field of automotive technology, the introduction of speed adaptation systems or speed limiters in cars could have positive effects on safety (Marchau et al, 2010). According to Hickman et al (2012) speed limiters have resulted in reductions of the number of crashes for commercial vehicles. reconstruction method…”

Unravelling the Complexity of Irregular Shiftwork, Fatigue and Sleep Health for Commercial Drivers and the Associated Implications for Roadway Safety

“…Drivers function daily in environments that present challenges for healthy behaviors—including truck stops, fleet terminals, shipping and receiving warehouses, and truck cabins—where it is often difficult to find facilities and space for recommended exercise and healthy eating options [ 8 , 11 , 12 , 21 , 22 ]. Thus, CMV drivers tend to lead sedentary lifestyles [ 23 ] and may be complacent or inattentive toward healthy behaviors. Long working hours, irregular sleep schedules, and lifestyle factors increase the chances of CMV drivers being susceptible to health risks such as obesity, cardiovascular disease, and metabolic disorders [ 12 , 18 , 24 , 25 , 26 , 27 , 28 , 29 ].…”

“…The consistent consumption of high-calorie, low-nutrient foods can lead to overweight and obesity. Excess weight affects 90% of CMV drivers and has numerous associated comorbid conditions, including cardiovascular disease and sleep, metabolic, and psychological disorders [ 8 , 13 , 17 , 23 , 26 , 33 , 35 , 36 , 37 , 38 ]. Additionally, evidence suggests that fatigue levels positively correlate with work stress, life stress, depression, and anxiety while having a negative relationship with life satisfaction, work happiness, and work satisfaction [ 3 , 39 , 40 ].…”

“…As noted previously, overweight and obesity—which may be as high as 90% in CMV drivers—and associated comorbidities, including obstructive sleep apnea (OSA), hypertension, cardiovascular and metabolic disorders, could have significant implications for fatigue and safety among this population [ 17 , 19 , 23 , 26 , 33 , 36 , 37 , 56 , 57 , 58 , 59 ]. In a naturalistic driving study with CMV drivers, Wiegand et al [ 60 ] found obese CMV drivers were 1.2 to 1.7 times more likely to be fatigued while driving and were at 1.37 times greater risk for being involved in a safety-critical event than non-obese drivers; obese drivers were almost twice as likely to be fatigued while involved in an at-fault safety-critical event [ 60 , 61 ].…”

“…Studies indicate that OSA is associated with decreased physical activity and increased preference for calorie-dense foods that are high in fat and carbohydrates, as well as hormone dysregulations that can stimulate appetite to exacerbate obesity through alterations in energy balance and metabolism [ 71 ]. Hypertension, impacting up to 40% of CMV drivers [ 23 , 24 ], is linked to OSA through mechanisms of action in the sympathetic nervous system that elevate heart rate and blood pressure in response to repetitive and stressful sympathetic activations. Hickman et al determined that hypertension was the second most predictive factor (after BMI) for having OSA among a cohort of 21,000 CMV drivers [ 23 ].…”
