The delay gives New Jersey truck drivers an exemption from the idling regulation while resting or sleeping in a sleeper berth until May 1, 2011.
The current Department of Environmental Protection regulation prohibits diesel-powered vehicles from idling for more than three consecutive minutes if the vehicle is stopped. The exemption allows for sleeper berth idling.
As part of a statewide effort by the department to reduce diesel emissions in New Jersey, the department approved a measure to phase out sleeper berth idling in July 2007.
