Steering modifications

Steering conversions

All vehicles converted from left-hand drive to right-hand drive must be converted in accordance with the Code of Practice for Steering Conversions for Left Hand Drives.

Vehicle Standards Bulletin (VSB) Number 4 National Code of Practice - Steering Conversions for Left Hand Drives Vehicles.

An engineering report prepared by a Chartered Professional Engineer, must be submitted specifying that the requirements of VSB Number 4 have been met.

For all steering conversions, an application to modify should be sent to Vehicles Standards. You will be sent a Statement of Requirements to complete.

Application to Modify Motor Vehicle - MR620 (891.8 KB PDF)

The statement of requirements is required by Department for Infrastructure and Transport before a vehicle can be booked for inspection.

Vehicles fitted with welded steering components must comply with the requirements set out in VSB Number 4. Welded steering components are not acceptable unless certified by a chartered professional engineer.

Modified steering components

Welding, heating or chroming axles, stub axles, steering arms and steering knuckle supports are not acceptable unless an engineering report prepared by a Chartered Professional Engineer, is presented, which demonstrates that the modifications are at least as strong as the original and contain no latent defects.

Steering wheels

Steering wheels are designed to minimise injury to the driver during a vehicle accident.

When replacing a steering wheel make sure that the new steering wheel complies with Australian Design Rule (ADR) requirements.

Replacement steering wheels must not be less than 330 mm in diameter. If the original steering wheel was designed with a recessed or padded hub, the replacement wheel must be of a similar design.

A non-standard aftermarket steering wheel may be fitted to passenger cars and derivatives manufactured prior to 1971. When selecting a replacement steering wheel ensure that it is firmly padded and is constructed so that it will bend on impact without splintering or cracking, and that no parts of the wheel are loose or cracked.

Passenger vehicles built after 1970 are required to comply with ADR 10. The replacement steering wheel must have the appropriate markings indicating that it complies with ADR 10. There are a number of steering wheels certified to ADR 10, so before purchasing an aftermarket steering wheel contact Vehicle Standards to ensure that it is acceptable.

Passenger vehicles manufactured after June 1995, which are required to comply with ADR 69 (full frontal impact occupant protection), may only be fitted with steering wheels certified by the vehicle manufacturer as suitable for that vehicle.

For example, if your vehicle has an airbag steering wheel as standard, the replacement must be the same. Fitting an aftermarket steering wheel to a vehicle that has an airbag in the original steering wheel is not acceptable.
