Indicates the existence of an option. Where the word 'may' is used, it indicates that use of the device is conditional, or optional. Usually, no specific requirement for design or application is intended.

1.5.9Shall#

Indicates that a statement is mandatory. Where certain requirements in the design or application of the device are described with the 'shall' stipulation, it is mandatory that, when an installation is made, these requirements be met.

1.5.10Should#

Indicates a recommendation. Where the word ‘should’ is used, it is considered to be recommended usage, but not mandatory. Any recommendation that is not applied must be based on sound traffic engineering judgement and documented.

1.5.14Registered Professional Engineer of Queensland (RPEQ)#

A person who is registered as a Registered Professional Engineer of Queensland (RPEQ), under the Professional Engineers Act 2002 (Qld) with the Board of Professional Engineers of Queensland.

1.5.15Innovative treatments#

Innovative treatments that provide improved safety, efficiency, and/or value-for-money outcomes are encouraged. Such treatments may include:

• a) innovative use of current devices
• b) alternative device layouts using existing and/or improved devices, and/or
• c) new devices or practices.

New or improved devices, treatments, or practices require approval by the Department of Transport and Main Roads (see Clause 1.8 for guidance about variations to optimal treatments) prior to their use or adoption.

For trials of new or innovative traffic control devices, treatments, or practices, a submission in accordance with the requirements of the Queensland Manual of Uniform Traffic Control Devices (MUTCD) Part 1 Clause 1.13 shall be submitted to TrafficEngineering.Support@tmr.qld.gov.au.

1.8Variation to treatments and Registered Professional Engineer of Queensland certification#

This Part of the Manual contains mandatory requirements (shall), recommendations (should) and options (may). The application of these mandatory requirements and recommendations is intended to provide the optimal level of safety and traffic efficiency. It is acknowledged that, in some instances, variations to these requirements and recommendations may be necessary and, as such, variations to these requirements and recommendations may be undertaken as follows:

1. a)Where recommendations (should) are not adopted, a risk assessment shall be undertaken and certified by a Registered Professional Engineer of Queensland (RPEQ).
2. b)Where mandatory requirements (shall) are not adopted, a risk assessment shall be undertaken and certified by an RPEQ. Notifications of variations to mandatory requirements (including all relevant information) shall be emailed to TrafficEngineering.Support@tmr.qld.gov.au for information purposes and for the benefit of identifying potential future practice changes – not for approval or endorsement. These variations may include learnings that may be attributed to the variation of a shall requirement, such as operational, cost or safety impacts.
3. c)Where innovative treatments (see Clause 1.5.15) that are outside the scope of the Queensland MUTCD are proposed to be adopted, a risk assessment shall be undertaken and certified by an RPEQ.
4. d)All proposed innovative treatments require approval by Transport and Main Roads prior to their use or adoption. Requests for approval of innovative treatments (including all relevant information) shall be emailed to TrafficEngineering.Support@tmr.qld.gov.au. As part of an approval to use or trial an innovative treatment, Transport and Main Roads may require that the applicant provides a detailed evaluation report on the performance and effectiveness of the treatment. Transport and Main Roads may use the results of the evaluation to identify potential future practice changes to this Part of the Manual.
5. e)The use of options (may) is not a variation to the optimal treatment and does not require certification by an RPEQ.
