Using the Speed Adviser smartphone app

Speed Adviser is an Intelligent Speed Adaptation (ISA) smartphone application (Application) designed and developed by Transport for NSW (TfNSW) to improve road safety by warning road users when they have exceeded the speed limit.

The Application monitors the current speed of the vehicle in which it is travelling, as determined by Global Positioning System (GPS) and map data, and provides guidance for users (through audible and visual alerts) when the legal speed limit changes or is exceeded.

Users must comply with the speed limit

It is an offence for a driver to drive at a speed over the speed limit applying to the driver for the length of road where the driver is driving. Applicable speed limits will be enforced in accordance with the law. You must comply with those requirements regardless of the vehicle's speed, the speed limit or speed zone shown on the Application.

You accept full responsibility for complying with all speed limits and applicable road laws and rules.

You acknowledge that the Application is designed to operate in designated geographical areas only, and outside those areas the Application may not be able to detect the speed limit or speed zone in which you are travelling.

Although every effort is made to ensure that the speed zones and speed limits displayed through the Application are accurate, the changing nature of speed zones and speed limits means that there may be a time lag in the Application's detection of a change to the speed zone or speed limit in the location in which you are travelling. The Application cannot warn drivers of changes displayed on electronic variable speed limit signs or temporary speed zones such as those used at sites where road works are being conducted.

Temporary or intermittent loss of GPS reception may occur in some geographical areas for reasons beyond TfNSW's control. TfNSW accepts no responsibility whatsoever for any failure of the Application to accurately determine the speed of your vehicle, the applicable speed limit or any unavailability of the Application.

TfNSW does not warrant, and you acknowledge that TfNSW does not warrant, that the speeds determined by the Application or the speed limits displayed are accurate. The speeds determined by the Application or the speed limits and speed zones displayed are no defence to any failure by you to comply with the sign-posted speed limits and speed zones.

NSW Road Rules prohibit Learner, P1 and P2 licence holders from using a mobile phone at all while driving or riding. Accordingly, such licence holders must not use Speed Adviser.

Your commitment to safe driving

The NSW Road Rules provide that it is illegal to use a mobile phone held in your hand while you're driving - to read, write or send text messages, listen to voicemail, make selections on an Application or even turn the phone on or off. It does not matter if you are moving or stopped at traffic lights, for example, it is illegal for you to use a phone held in your hand while you're driving.

The Application will advise you of changes in speed limits and issue warnings when you're driving above the posted speed limit. The Application is designed to be used completely hands-free and will require no interaction from the user while driving.

To use the Application you need to agree to the terms and conditions of the Application and hold an unrestricted licence.
