​Indian Ocean Drive

Safety review report

After a series of serious crashes on Indian Ocean Drive, between Two Rocks and Lancelin, an Indian Ocean Drive Safety Review Group was convened in August 2017 to examine road safety issues on this stretch of road and to recommend to Government what measures could be taken to improve safety.

Drawing upon the expertise of senior and experienced staff from the Road Safety Commission, Western Australia Police Force and Main Roads, the review group adopted a ‘Safe System’ approach to reviewing the issues and considering recommended actions.

Latest news

On 8 November 2017 a joint-ministerial announcement was made by Hon Michelle Roberts Minister for Police; Road Safety and Hon Rita Saffioti Minister for Transport; Planning; Lands, releasing the Indian Ocean Drive Safety Review Report, which outlines a number of recommendations for improving safety.

We would like to thank road users for their patience while these important safety improvement works are underway.

Scope of current works

A number of short-term responses have been agreed for immediate action, including:

  • Reduction of speed limit from 110 km/h to 100 km/h, effective as of 9 November 2017. This recommendation was informed by a ‘real world’ speed assessment undertaken as part of the review, coupled with speed data, infringements from Western Australia Police Force and public feedback. Based on this data, the current median operating speed on this stretch of road was found to vary from 99-to-103km/h.
    • As a result, the report “determined that reducing the speed limit until other infrastructure enhancements could be implemented would improve public safety”
    • The speed limit change will only increase travel time between Two Rocks Turnoff and Lancelin by an extra three minutes. The 100 km/h speed limit will start at the end of the 90 km/h zone located approximately 4 km south of Breakwater Drive, and continue until the start of the 90 km/h just south of K.W. Road.
    • The speed limit on this stretch will be reassessed once all recommended infrastructure improvements have been finalised.
  • Installation of edge and centre audible line marking. By providing an audible warning to prompt driver recovery, this treatment has the capacity to reduce head-on crashes as well as single vehicle ‘run-off to the right’ crashes. The installation of the audible lines has already commenced and will be completed by February 2018. The works will be managed under stop/slow traffic management and short delays can be expected. For the safety of road users and road workers, motorists are requested to obey the directions of traffic management signs and controllers.
  • Installation of passing lanes. In September 2017, the Federal and State Governments committed $7 million for upgrades on Indian Ocean Drive, between Two Rocks Turnoff and Lancelin (funded from the Regional Road Safety package). Four additional passing lanes are planned, two northbound and two southbound between Seabird and Lancelin. One pair of passing lanes either side of the Ledge Point intersection, will be delivered in 2017-18. The second pair, located approximately 8 km further south, will be delivered in 2018-19.
  • Improved signage. Installation of curve warning signs, wildlife warning signs and replacement of guide signs will also be undertaken, expected to be completed by February 2018.

 

 

​Key benefits

We are implementing these immediate treatments recommended by the Indian Ocean Drive Safety Review Report to improve the safety of road users on this road. Planning is progressing to enable implementation of further mid-term treatments.
