Australia: New ADR for Lane departure warning systems for all heavy vehicles

 

On the Federal Register of Legislation, new and amended standards to specify requirements for lane departure warning systems fitted to omnibuses, medium and heavy goods vehicles have been published.

Following an amendment to the implementation date made by the Minister in March, ADR 99/00 – Lane Departure Warning Systems for heavy vehicles over 3.5 tonnes will apply from 1 September 2027 for all vehicles.

The new ADR 99/01 – Lane Departure Warning Systems will apply from 1 September 2026 for new models and 1 September 2028 for all vehicles.

The purpose of this Regulation is to establish consistent guidelines for Lane Departure Warning Systems (LDWS) installed in motor vehicles falling under categories M2, M3, N2, and N3[1], primarily utilized on highways.

The implementation of LDWS in these vehicle categories is particularly advantageous, especially in scenarios involving prolonged and monotonous driving. The primary aim of installing such systems is to assist drivers who may be distracted or fatigued by alerting them if the vehicle unintentionally veers out of its lane.

While LDWS installation generally benefits vehicles in these categories, there are certain subgroups where the extent of benefit is uncertain due to their predominant use in conditions other than highway driving (such as buses with standing passengers, i.e., Classes I, II, and A, off-road vehicles, construction vehicles, special purpose vehicles, etc.). Moreover, there are subgroups where installing LDWS may pose technical challenges, such as vehicles with split windshields, asymmetrical cabs, thick windshields, front hood vehicles, or those with front-mounted equipment.

The LDWS is required to automatically detect any unintended deviation of the vehicle from its designated lane and promptly alert the driver.

The system must deliver a warning that effectively grabs the attention of an inattentive driver during critical situations.

Due to the diverse range of traffic conditions and infrastructure features, it’s not feasible for the Regulation to encompass all possible scenarios within its type-approval process. However, the system should not issue false warnings triggered by real-world conditions and features to the extent that it prompts drivers to disable the system.
