Heavy vehicles over 12 tonnes
Tarpaulins, load covers and load nets can be used to restrain loose bulk loads in open topped vehicles.
The use of wetting or skinning agents alone is not acceptable but may be used in conjunction with a suitable load cover.
Loose loads should never be transported on flat bed or
platform type vehicles without sides or gates, or tipper bodies without
Bodies with poorly fitting sides and gates should not be used to transport fine particle materials such as sand.
If the mandatory load cover is inappropriate or impractical you can apply for an exemption. You can apply in writing to the MVR.
