THE speed limit along Two Rocks Road could drop to 70km/h following a safety review.
A report on the Wanneroo council meeting agenda recommends the City ask Main Roads WA to reduce the speed limit from 90km/h to 70km/h between Yanchep and Two Rocks.
The report said crash data recorded 23 crashes on the 6.5km length of road between 2010 and 2014.
“Outcomes of the 23 crashes recorded included two fatalities, five hospital admission crashes and three crashes requiring medical attention,” it said.
More recent fatal crashes included the death of Diana Garcia (47) on March 6 when a Hyundai Sonata crashed head-on into her Mitsubishi Mirage.
A Nollamara man (24), who was driving the Hyundai, and a male front- seat passenger (30) also died.
In September 2015, a 20-year-old man was killed in a head-on vehicle collision on the same road.
Due to be considered by the council on April 26, the report said crash data showed that eight of the 23 crashes took place at night and nine involved cars leaving the road. “While it is noted that the 85th percentile speed (operating speed) is close to the posted speed limit, it can be established from the crash history that speed has contributed to the severity of the crashes,” it said.
“The ‘safe speed’ cornerstone recognises that under a safe systems approach, 70km/h is considered as being the highest survivable speed for a head-on collision and 50km/h for a right-angle collision.
“Reducing the speed limit on Two Rocks Road to 70km/h will play a significant role in improving safety of the road.”
The council will consider asking Main Roads to do a speed zone review between 150m north of the former Club Capricorn entrance and 300m south of Reef Break Drive.
