We're upgrading 8 main roads in Melbourne's west as well as improving and maintaining more than 260km of road from Footscray to Werribee.
Limiting access to turning left-in and left-out only is in the interest of safety for all road users.
To reduce the risk of side impact collisions or T-bone crashes, it is important to reduce the number of right-hand turn access points. This means that drivers need to perform a U-turn at dedicated bays or traffic lights, which reduces congestion and improves traffic flow.

Questions & answers
Why do we restrict right-hand turn access?
When we upgrade main roads by adding news lanes, it’s important to restrict where cars can turn right (across multiple lanes) into or out of driveways and side roads.
We do this for several reasons:
- to reduce congestion and keep traffic flow moving.
What are the benefits of restricting right-hand turn access points?
- Safety – we restrict right-hand turn access in order to keep the road as safe as possible and avoid cars crossing multiple lanes of traffic. ‘Left-in’ and ‘left-out only’ is safer and ensures traffic keeps moving.
Reducing the number of right-hand turns across multiple lanes of traffic also reduces the chance of side impact collisions (often called ‘T-bones’).
- Improved Traffic Flow – by controlling where cars can turn right, congestion is reduced by avoiding cars from ‘queueing’ behind a car turning right, which thereby improves traffic flow.
How will these changes impact my travel time?
When the road upgrade is complete, you may have to travel slightly further to access the new dedicated U-turn bays or traffic lights. However, your journey will be safer and more reliable.
We can control the timing of traffic lights based on demand at different times of the day, which can improve overall travel times.
How will I get across a lane and into the right turn lane to do a U-turn?
Breaks in traffic provided by traffic lights further up the road will give drivers time to enter the road from driveways and side roads.
If a driver wishes to change direction, they then can make a U-turn at dedicated bays or traffic lights.
Will the new U-turn bays or traffic lights allow for big vehicles?
Vehicles up to 12.5 metres can generally do a U-turn at the traffic lights if permitted.
Vehicles larger than 12.5 meters will need to plan ahead to identify alternative travel routes.
How do you decide where median access is allowed?
The location and design of access points must consider the following:
- volume of traffic
- type of traffic
- function of the road
The design of the road upgrade and access management approach must comply with VicRoads and AustRoads guidelines.
How do you determine the best locations for breaks and U-turn bays?
The location of an intersection is primarily determined by the existing road network and the needs of surrounding property development.
Other factors also include:
- environmental factors such as ground levels and watercourses. It is desirable that median access points are located on straight and generally flat sections of road
- transport needs for the network
- driver and pedestrian line of sight distance requirements.
