Introduction

Roads and Maritime Services 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 Roads and

Maritime compliance officers as part of

enforcement programs.

The 2019 data included in this update is for

Quarter 2 April to June 2019.

This report summaries key statistics and trends of heavy vehicle compliance programs based on intercepts and

notices issued by RMS enforcement officers as part of enforcement programs.

46,954 vehicle combinations were intercepted through Special Operations (14,743), On Road Enforcement

(6,364) and Heavy Vehicle Safety Stations (25,847).

88,421 vehicle units inspected issuing a total of 12,749 notices to 10,136 vehicle units, excluding inspections

and notices issued through the Heavy Vehicle Inspection Scheme (HVIS).

8,003 defect notices issued during enforcement programs including Heavy Vehicle Safety Stations, On-Road

Enforcement and Special Operations:

o 5,460 (68.2%) minor defect

o 1,558 (19.5%) formal warning defect

o 936 (11.7%) major defect

o 49 (0.6%) major grounded defects

11,368 defect notices were issued through the Heavy Vehicle Inspection Scheme:

o 8,641 (76.0%) minor defect

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.

The heavy vehicle compliance rate of 88.5 per cent in 2019 Quarter 2 has the highest quarterly compliance

rate over the last 5 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 Heavy Vehicle Inspection Scheme (HVIS) is lower compared

to other enforcement programs because the vehicle inspection for roadworthiness and registration is more

comprehensive than inspection at a Heavy Vehicle Safety Station. The 2019 Q2 compliance rate (88.5%)

has improved by 1.2 per cent over the previous quarter 2019 Q1 compliance rate (87.3%).

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 2019 Q2, heavy vehicles carrying aggregate/soil are

attracting the most notices in terms of load, closely followed by building materials/supplies, machinery and

Primary Produce.

Number of driver directions by year Driver direction relates to fatigue offences where drivers are directed to take a mandatory rest break.

Driver direction notices are issued through the RMS enforcement compliance programs - Heavy Vehicle

Safety Stations, On-Road Enforcement and Special Operations.

The proportion of Driver direction notices for Heavy Vehicle Safety Station reduced by 19.5 per cent and for

Special Operation increased by 19 per cent in quarter 2, 2019 compared to the same time in previous year
