The Liberal National Government is expanding Main Roads Western Australia's Incident Response Service (IRS) as part of the Traffic Congestion Management Program.
Transport Minister Bill Marmion said the service was evolving to meet the future needs of Perth road users.
"The IRS has been operating on Monday to Friday since its inception in 2012," Mr Marmion said.
"We recognise that incidents can occur at any time and weekends can be just as busy as weekdays, so the service will now operate seven days a week.
"The IRS has proved to be a vital service for Perth, ensuring incidents and debris are cleared quickly and traffic returned to normal conditions to minimise congestion and delays."
The expanded coverage also includes new vehicles to enhance the service across Perth. A new Road Rake will help keep traffic moving while collecting roadside litter and debris on the metropolitan road network.
"Debris on the road network causes both safety and congestion issues, especially when items are impacting live traffic lanes," the Minister said.
"The new Road Rake is a smarter, more efficient way to collect debris from traffic lanes with staff remaining safely inside the vehicle.
"This means we can keep Perth drivers moving, without the need to close traffic lanes and cause further disruptions in the process."
A new incident response vehicle, the first of its kind in Australia, also provides enhanced safety protection for staff attending to traffic incidents in high-speed environments.
"Investing in a range of measures means we can continue to meet the needs of a growing population and keep traffic flowing," Mr Marmion said.
The Incident Response Service will operate from 7am to 6pm on weekends
