Mass & Dimensions

  • What are Higher Mass Limits?

    Higher Mass Limits allow eligible vehicles with road-friendly suspension and the required mass accreditation to carry higher axle-group masses on an approved HML route or area.

  • What are General Mass Limits?

    General Mass Limits are the default axle-group and gross-mass limits for heavy vehicles unless a lawful exception, exemption, notice, permit, HML entitlement or PBS approval applies.
