‘Day cab’ means a type of cab that is not a sleeper cab.
If a new heavy-duty vehicle cannot be attributed to a vehicle sub-group because information on the cab type or engine power is not available, it shall be attributed to the long-haul (LH) vehicle sub-group corresponding to its chassis type (rigid lorry or tractor) and axle configuration (4 × 2 or 6 × 2).
Where a new heavy-duty vehicle is attributed to vehicle sub-group 4-UD, but data on the CO2 emissions in g/km are not available for the UDL or UDR mission profiles as defined in Table 2 of point 2.1, the new heavy-duty vehicle shall be attributed to vehicle sub-group 4-RD.
