Driver fatigue is a complex and recurrent problem characterized by a driver’s reduced ability to perform tasks on the road. Long driving hours, combined with other factors like stress and sleep deprivation, can lead to driver fatigue or distraction. Given the risk this poses to other road users, preventative measures must be taken to help increase road safety.
One measure currently in place to reduce commercial vehicle driver fatigue is the Commercial Vehicle Drivers Hours of Service Regulations (2009), which is a federal regulation. This regulation sets the maximum amount of hours drivers are allowed to drive in a given work cycle, and the minimum amount of off-duty time required between shifts. However, factors occurring outside of duty cycle time may also cause driver fatigue or distraction.
