A controversial electronic billboard overlooking the Kwinana Freeway will be reactivated next week after a safety audit found it complied with Main Roads guidelines.

The billboard, near the Bull Creek train station on Leach Highway, drew criticism in April last year when drivers claimed it distracted their attention from the road.

It was subsequently revealed the State Government approved its installation without a safety audit, prompting the RAC to call for its immediate removal.

The billboard was the first under a deal to install 10 in prominent freeway locations, which the Government hoped would raise more than $7 million over a decade to be spent on congestion management and public transport initiatives.

Shortly after the Bull Creek Station billboard was switched off, it was revealed the Government was ultimately responsible for the $680,000 installation cost through a revenue sharing arrangement.

At that time the Government also said it would have to pay for the removal or relocation of the sign, if it was not deemed safe enough to be switched back on.

Billboard complies with government policy

The Department of Transport sought an assessment of the billboard's placement from road safety consultants the ARRB Group.

That review found the billboard complied with state policy on advertising signs, although it recommended a lower illumination setting, and with a longer timeframe for each image.

Transport Minister Dean Nalder said those recommendations would be taken on board when the billboard was reactivated on July 8.

"We will adopt a conservative 'start-up' commissioning approach which is well within the Main Roads WA guidelines for advertising signs," he said.

"To assist road users to adapt to change, dwell times or the time allocated to particular advertisements will be extended to 60 seconds (from 45 seconds) and a lighting specialist will be in attendance to validate luminance levels."

Main Roads will monitor driver responses to the billboard over the coming months.
