Amendment: Heavy-duty vehicle emissions, OBD & PEMS (Reg 582/2011)

This regulation updates existing rules for heavy-duty vehicles to ensure their emissions are accurately measured and controlled. It focuses on improving testing methods and data access to promote cleaner air and meet environmental targets.

The changes affect vehicle manufacturers and repair services. They will need to comply with new standards for auxiliary emission strategies, onboard diagnostic information, and the use of portable emissions measurement systems for particle number testing.
