(a)a Euro VI vehicle (complying steer axle);

(b)a Euro VI vehicle (single steer axle);

(c)a Euro VI vehicle (twinsteer).

(2)The Euro VI vehicle mass transfer allowance applies as an exception to the general mass limits for an eligible vehicle as stated in subsections (4) and (5).(3)The Euro VI vehicle mass transfer allowance applies to an eligible vehicle in addition to any concessional mass limits or higher mass limits that apply to the vehicle.Note—See also section 3 of Schedule 2 and section 3 of Schedule 5.(4)The mass on the drive axle of an eligible vehicle may be increased by up to 0.5t if there is a corresponding decrease in the mass on—

(a)for a Euro VI vehicle (complying steer axle) or Euro VI vehicle (single steer axle)—the vehicle’s steer axle; or

(b)for a Euro VI vehicle (twinsteer)—the vehicle’s twinsteer axle group.

(5)However, the Euro VI vehicle mass transfer allowance does not apply to an eligible vehicle if the transfer of mass between the vehicle’s steer axle, or twinsteer axle group, and drive axle under subsection (4) results in—

(a)the sum of the steer axle, or twinsteer axle group, and drive axle being more than—

(i)if the concessional mass limits apply to the vehicle’s axles—the sum of the concessional mass limits for the axles; or

(ii)if the higher mass limits apply to the vehicle’s axles—the sum of the higher mass limits for the axles; or

(iii)otherwise—the sum of the general mass limits for the axles; or

(b)an increase in the mass on the drive axle that is more than 0.5t; or

(c)a decrease in the mass on the steer axle, or twinsteer axle group, that does not correspond to the increase in mass on the drive axle; or

(d)the mass of the vehicle being more than—

(i)if the concessional mass limits apply to the vehicle—the mass limit that applies to the vehicle under section 2 of Schedule 2; or

(ii)if the higher mass limits apply to the vehicle—the mass limit that applies to the vehicle under section 2 of Schedule 5; or

(iii)otherwise—the general mass limits that apply to the vehicle under section 2 of Schedule 1.

(6)This section has effect subject to section 2.2Axle spacing(1)This section applies if—

(a)the mass of the drive axle within a particular axle spacing on the eligible vehicle is permitted by the Euro VI vehicle mass transfer allowance to be increased by up to 0.5t; and

(b)the increase would otherwise result in a breach of the mass limits for the axle groups and any single axles within the axle spacing.

(2)Subject to subsection (3), the mass for any single axles and axle groups within the axle spacing is permitted to be increased but must not be more than the mass otherwise permitted for the axle spacing increased by the same amount.(3)However, the increased mass must be offset by adjusting the masses on the steer axle or twinsteer axle group, whether within the same axle spacing or different axle spacings.Note—Requirements about the mass of a heavy vehicle relating to an axle spacing of a heavy vehicle are referred to in section 5 of Schedule 1.
