| a M1 vehicles derived from N1 vehicles: M1 vehicles with an R point > 850 mm from the ground and a total permissible laden mass more than 2 500 kg have to fulfil the limit values of N1 (2 500 kg < mass ≤ 3 500 kg). | ||||
| b + two years for new vehicle type and + one year for new vehicles registration. | ||||
| Limit values shall be increased by 1dB (2 dB(A) for N3 and M3 categories) for vehicles that meet the relevant definition for off-road vehicles set out in point 4 of Part A of Annex II to Directive 2007/46/EC. | ||||
| For M1 vehicles the increased limit values for off-road vehicles are only valid if the technically permissible maximum laden mass > 2 tonnes. | ||||
| Limit values shall be increased by 2 db(A) for wheelchair accessible vehicles and armoured vehicles, as defined in Annex II to Directive 2007/46/EC. | ||||
