An Educational Intervention to Promote Safe Driving
The general aim of the study is to promote safe, economic, and environmental-friendly driving among long-haul truck drivers. To do this, the investigators will conduct an on-road study on i) the relationship of driver sleepiness and stress with driving behaviour and fuel consumption and ii) effectiveness of an educational intervention in mitigating sleepiness at the wheel. The educational intervention is designed to be employed by occupational health care professionals in the future. This solution clearly facilitates the implementation of the intervention into practice if it turns out to be effective.
The investigators specified research questions are the following:
- Do truck driver sleepiness and stress at the wheel reach levels that affect driving behaviour, fuel consumption and carbon emissions?
- What are the sources of sub-optimal arousal at the wheel in truck drivers?
- Can truck driver sleepiness be mitigated by an educational intervention, and if yes, does it improve driving behaviour and decrease fuel consumption and carbon emissions as well?

|Official Title:||An Educational Intervention to Promote Safe and Economic Truck Driving|
- driver sleepiness [ Time Frame: one year ] [ Designated as safety issue: Yes ]Self-reported sleepiness measured by the the Karolinska Sleepiness Scale Questionnaire and behavioral sleepiness measured by the Observer Rating of Drowsiness (based on video materia).
- driver stress [ Time Frame: one year ] [ Designated as safety issue: Yes ]Self-rating scale of stress and heart rate measures of stress (heart rate variability)
- sleep [ Time Frame: one year ] [ Designated as safety issue: No ]wrist-worn actigraphy and sleep diary based measures of sleep quantity, timing and quality
- driving behaviour [ Time Frame: one year ] [ Designated as safety issue: Yes ]vehicle movement-based measures of driving behaviour (speed, accelerations, deceleration)

Experimental: Fatigue management training
Experimental group subjects participated in a single half-day fatigue management training session.
Behavioral: Fatigue management training
Experimental group took part in a single half-day (4 hours) fatigue management training grounded on Problem Based Learning (PBL).
No Intervention: No fatigue management training
The control group subjects did not participate in the fatigue management training.
