As reported in July, the Department of Transport and Main Roads in Queensland has determined that clip-on flexible warning signs may be used on long vehicle combinations from December 1, 2012.
According to the CVIAQ, vehicle warning signs in Queensland must currently meet a number of requirements, including being made from sheet steel at least 0.8mm thick or of material at least the same stiffness, or being attached by an adhesive. Flexible signs have not been permitted as yet.
However, the Department of Transport and Main Roads has recently received a number of enquiries from vehicle operators and the transport industry about the use of flexible material when vehicle warning signs, such as ‘long vehicle’ and ‘road train’, are required to be fitted to certain vehicle combinations.
Asa result, flexible signs are now permitted provided the following requirements are met:
- The sign must be secured to the vehicle by clip type attachments. The attachment of flexible signs by ropes is not acceptable.
- The sign must be attached to a vertical surface and in a way that ensures the wording and borders of the sign are clearly visible.
- The sign must be securely attached in a way that does not allow the sign to flutter, flap or otherwise warp under all operating conditions.
- The sign must meet all other requirements of Schedule 1 Section 52 of the Transport Operations (Road Use Management—Vehicle Standards and Safety) Regulation 2010. For the full requirements for vehicle warning signs under the regulation please contact Vehicle Standards and Modification Advice on (07) 3114 5844 Monday to Friday, 9:30 am–4:30 pm.
Clip-on signs may only be used on vehicle combinations that operate under the Guideline for Multi-combination Vehicles, Form 1. Vehicles that operate under a permit or other guideline must comply with the signage requirement in the respective permit or guideline.
The CVIAQ points out the use of flexible signs has been allowed only in Queensland and may not be recognised in other states or territories. Vehicle operators who travel between states and territories must ensure that vehicle warning signs fitted to their vehicles comply with the requirements in each state or territory.
