Over a period of two years, 26.3 thousand road freight shipments were recorded. The
records include information about truckload companies, drivers, and the causes of noncompliance
and delays in deliveries. Logistic regression based in working conditions as
independent variables was used to predict non-compliance deliveries attributed to cargo
drivers. Results show that vehicle type, medical coverage and social security, level of
stress, work dissatisfaction, and transit time were strongly associated with out-of-timedelays
in deliveries. The proposed model is a promising tool to improve the performance
of truckload companies and it may motivate to benefit working conditions of truckers.
