• Has no impairment of a hand or finger which interferes with prehension or power grasping or has been granted a skill performance evaluation certificate pursuant to 49 CFR 391.49. • Has no impairment of an arm, foot, or leg which interferes with the ability to perform normal tasks associated with operating a CMV or has been granted a skill performance evaluation certificate pursuant to 49 CFR 391.49.

Not wearing a safety belt appears to be an indicator of commercial driver risk as well. In the LTCCS, truck crash involvements could be separated into three categories: single-vehicle, multivehicle where the truck/truck driver is assigned the Criti

A meta-analysis by Jonah (1997) documented correlations between sensation-seeking and risky driving behaviors such as speeding, frequent lane changes, alcohol use, and failure to wear safety belts.

, the highest seen were between social deviance and speeding, and between social deviance and crashes. Several project interviews mentioned an "attitude of compliance" as an important safety-related characteristic of good commercial drivers.

From page 15... ...
Numerous studies have related attitudes, subjective norms, or perceived behavioral control to intentions and to behavior. All three have been shown to be predictors of dangerous driving behaviors (Parker et al.

Tests on a group of commercial drivers compared these dynamic skills to performance on an interactive truck driving simulator. Dynamic or "neurocognitive" skills most predictive of simulator performance included depth perception, peripheral vision/field-of-view, field independence/dependence, attention sharing, and range of motion.

Medical conditions could affect driver safety by causing general decreases in psychomotor skill and cognitive functions. Such chronic performance decrements might include decreases in flexibility, decreases in alertness, or

Many of these individuals would be highperforming and reliable long-term employees were it not for their health problems. In the LTCCS, commercial drivers aged 51+ were 17% less likely than younger drivers to be at fault in multivehicle crashes, and yet these drivers are those most like to have reduced service owing to chronic medical conditions.

The latter includes both at-fault and non-at-fault involvements, consistent with driver records that show crash involvements but not necessarily principal fault or cause. Truck/Truck Driver CR Percentages for Single- vs.

The focus here is on the persistent personality characteristics of individuals that affect their likelihood of quitting. The "Big Five" Personality Traits The "Big Five" personality traits are extraversion, openness to experience, conscientiousness, agreeableness, and emotional stability, and cognitive skills.

From page 22... ...
However, to the extent that openness is associated with cognitive skill, this relationship is likely to be reversed for truck drivers. Extraversion showed a small but inconsistent relationship to turnover.
|
From page 23... ...
The ability to schedule oneself to meet the needs of shippers and consignees, while taking account of HOS rules and changing traffic and weather conditions, requires cognitive skill. From the driver's point of view, the number of miles a TL driver can complete depends on many factors besides the driver's own effort.
