(a)for a radial ply tyre—825kPa; or
(b)for another type of tyre—700kPa.

Example—

The manufacturer’s mass limits for a radial tyre are—

at a cold inflated pressure of 200–900kPa—5t
at a cold inflated pressure greater than 900kPa—6t.

Because the latter mass limit (6t) only applies at a cold inflated pressure above the threshold value of 825kPa mentioned in paragraph (a), the applicable manufacturer’s mass limits for the tyre is 5t.

(3)The mass exception applies as an exception to the general mass limits for the tri-axle group as stated in subsection (4).
(4)The tri-axle group may be loaded up to 21t.
(5)This section has effect subject to sections 2 to 5.

2Increased mass to be offset as regards the heavy vehicle

(1)The application of the mass exception to the heavy vehicle is contingent on—
(a)there being a corresponding adjustment in the mass of other axles on the vehicle, but so that the sum of all the axles does not exceed the sum of the general mass limits for all the axles; and
(b)compliance with the applicable general mass limits for each of those other axles on the vehicle as so adjusted; and
(c)an adjustment by way of decrease for any of those other axles on the vehicle not exceeding 1t; and
(d)mass of the vehicle, whether loaded or not, not exceeding the mass determined by applying section 2 of Schedule 1 (but with the amount stated in that section for an axle group or single axle changed in line with any adjustment permitted by the mass exception as applying to the vehicle).
(2)A reference in this section to other axles on the vehicle is a reference to all the single axles (if any) and axle groups (if any) on the vehicle other than the tri-axle group to which the mass exception applies.

3Axle spacing

(1)This section applies where—
(a)the mass of a tri-axle group within a particular axle spacing on the heavy vehicle is permitted by the mass exception to be increased by a particular amount; 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 the single axles (if any) and axle groups within the axle spacing is permitted to be increased but must not exceed 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 other axle groups or single axles, 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.

4Adjustments

An adjustment under this Schedule may be made by way of—
(a)one or more decreases only; or
(b)a combination of one or more decreases and one or more increases.

5Steer axles and steering axle groups excluded

This Schedule does not permit the mass limit imposed on a steer axle or twinsteer axle group to be increased or decreased.

(b)the load does not become dislodged from the vehicle.

Examples of load movement that may be permitted under subsection (2)—

a load contained within the sides or enclosure of the heavy vehicle that is restrained from moving horizontally may be able to move vertically
a load of very light objects, or a loose bulk load, that is contained within the sides or enclosure of the heavy vehicle may be able to move horizontally and vertically
a bulk liquid load contained within the sides or enclosure of the heavy vehicle
(3)For subsection (1), the circumstances are that the loaded vehicle is subjected to—
(a)any of the following, separately—
(i)0.8g deceleration in a forward direction;
(ii)0.5g deceleration in a rearward direction;
(iii)0.5g acceleration in a lateral direction; and
(b)if friction or limited vertical displacement is relied on to comply with paragraph (a)—0.2g acceleration in a vertical direction relative to the load.
(4)However, the heavy vehicle’s load restraint system is taken to comply with subsection (1) for a journey if—
(a)a mass or dimension exemption is in force for the vehicle for the journey; and
(b)the vehicle complies with the mass or dimension exemption; and
(c)an engineer has given a certificate—
(i)describing the load restraint system; and
(ii)certifying that the load restraint system is suitable to safely restrain the load, taking into consideration the nature of the load and the conditions reasonably expected to be experienced during the journey; and
(d)the driver of the vehicle keeps a copy of the engineer’s certificate in the driver’s possession during the journey.

Note—

Mass or dimension exemptions are dealt with in Division 2 and Division 3 of Part 4.5 of the Law.
(5)In this section—
