The reported safety of Coolgardie–Esperance Highway has varied between assessments. Reports commissioned by the Royal Automobile Club of Western Australia (RAC) in 2006 and 2008 give the entire highway a three-star safety rating out of five. The state's overall highway network was generally rated as three-star or four-star, with around 10% in 2006 and 5% in 2008 receiving a two-star rating. The National Highway section was assessed by the Australian Automobile Association in 2011 to be among the lowest risk highways in the country, based on total number of casualty crashes per length of road. However, individual risk based on casualty crash rates per vehicle kilometre travelled was assessed as medium-high. In 2013, that portion of the highway was assessed as having 7% of its length rated as one-star, 47% as two-star, and 46% as three-star out of five stars.
