Introduction
Transport for NSW aims to improve road safety
for the heavy vehicle industry and the broader
community through effective regulatory programs
and high-quality compliance, enforcement and
adjudication programs and systems.
This update summaries key statistics and trends
of the heavy vehicle compliance programs based
on intercepts and notices issued by TfNSW
compliance officers as part of enforcement
programs.
The 2020 data included in this update is for
Quarter 4 - October 2020 to December 2020.
Key Findings – Quarter 4, 2020 This quarter experienced a higher number of notices issued to vehicle units (10,195). The lowest compliance rate
(86.3%) over the last five quarters with 74,415 vehicle units was inspected, excluding inspections and notices issued
through the Heavy Vehicle Inspection Scheme.

Intercepts Roads and Maritime Enforcement Operations inspectors perform random and targeted intercepts and
inspections as part of on-road enforcement action, Heavy Vehicle Safety Station (HVSS) inspections,
targeted special operations.
The numbers of vehicle combinations intercepted by enforcement program.
Note: intercepts are unscheduled inspections of a vehicle at Heavy Vehicle Safety Station, On-Road Enforcement or Special Operation.
Compliance performance The percentage of vehicles issued one or more notices (defects, breaches, directions, warnings and
penalty infringement notices) across the enforcement programs is an indicator of overall compliance
performance. This excludes notices issued under the Heavy Vehicle Inspection Scheme as part of the
registration process.
Heavy vehicle compliance (excluding HVIS) has been relatively steady over the past five quarters.

Compliance by enforcement program Enforcement Operations provide several frontline services delivered by Enforcement Operations
Inspectors:
Heavy vehicle inspection scheme (HVIS):
Detailed inspections of heavy vehicles for roadworthiness and vehicle standards for registration
renewal.
Enforcement Programs (excluding HVIS):
Monitoring fatigue management.
Checking for valid registration and driver licences, outstanding defects, permit compliance and
overloading of vehicles.
Checking to ensure relevant load restraint guidelines have been followed.
Performing detailed mechanical, steering and suspension inspections.
The compliance rate of vehicles inspected at the Heavy Vehicle Inspection Scheme (HVIS) is lower than
other enforcement programs because the vehicle inspection for roadworthiness and registration is more
comprehensive than inspection at a Heavy Vehicle Safety Station. This quarter (2020 Q4) compliance rate
(55.7%) is 3.6 per cent lower than the previous quarter, with 22,640 vehicles inspected.

Industry load type During intercepts and when a notice is issued, the heavy vehicle load is recorded. Load type is an indicator
for the industry the heavy vehicle is engaged with.
Notice issued by load type includes enforcement programs Heavy Vehicle Safety Stations (HVSS), On
Road Enforcement (ORE) and Special Operations (Ops).
Based on load type recorded during intercepts in 2020 Q4, heavy vehicles carrying aggregate/soil attract
the most notices in terms of load, closely followed by building materials/supplies, primary produce and
machinery.
Heavy Vehicle Compliance Snapshot, Quarter 4 2020 Page 9
Defect fault types and compliance Analysis of defect fault types identified during inspections and intercepts indicates that brakes continue to
be the most common defect type. Brakes are the largest category of defects comprising 19.0 per cent minor
defect and 3.3 per cent major defects.
Major and Minor defects' compliance rate is consistent over the past five quarters from October 2019 to
December 2020.
Note: Major defects: include Major and Major grounded defect faults and compliance
Minor defects include Minor, formal warning and self clearing defect faults and compliance.
