“Heavy-duty diesel vehicles were measured for noise level, whole-body vibration from the driver’s seat, and in-cab air quality while the vehicles were parked with engine idling at a rest area and while they were driven.
“These baseline data will help similar studies determine whether new truck designs have changed these conditions for drivers.
“Long-haul truck drivers can potentially be exposed to air pollutants within the cab and sleeping berth …while the vehicle is parked with the engine idling at truck-travel– rest centers. Relationships between diesel vehicle emissions and human health effects have been shown in numerous studies (12)
“…long-haul trucks have a tendency to self-pollute the cab during periods of (extended) parked-idling conditions.”
