Monash Freeway Truck Trial

We’re exploring new and innovative ways to manage the Monash Freeway, to encourage all road users to share the road and drive safely.

What has happened so far?

The first stage of the trial involved a 90 km/h reduced speed limit for trucks over 4.5 tonnes along the Monash Freeway, between Huntingdale Road in Mount Waverley and Jacksons Road in Noble Park. The speed limit remained at 100km/h for all other vehicles. The trial ran from August 2016 until March 2017. 

Early findings from the trial showed that the reduced speed didn’t curb tailgating behaviour by trucks or cars in the right-hand lane, but did slightly reduce overall speeds. Strong feedback from motorists about their experience of the trial was also very informative, with many drivers witnessing increased weaving between trucks and cars in the far right lane.

We then focused our attention on Stage 2 of the trial, removing trucks from the far right hand lane. This trial commenced on 5 February 2018 and will run for a period of nine months unless trial results indicate otherwise. Restrictions will apply to trucks travelling in both directions between Huntingdale Road, Mount Waverley and Jacksons Road, Noble Park. Truck lane restrictions can improve safety by reducing the number of lane changes undertaken by cars and trucks.

What happens next? 

Thank you to all those that shared their experiences on the Monash Freeway during the two stages of the trial on our online engagement website, engage VicRoads. We are currently reviewing all of your comments which will help inform the decision of whether to permanently apply the restrictions.

Why the Monash Freeway?

The Monash Freeway was chosen because it’s one of Victoria’s busiest freight routes with over 200,000 cars and trucks driving along it every day. The freeway is also four lanes which allows for safer overtaking.

A shared responsibility

The road is a truck driver’s workplace and we share a responsibility to ensure everyone’s workplace is safe and as hassle free as possible.

You should play your part to keep truck drivers safe by not driving in or changing lanes into the braking gap of a truck.

Large trucks travelling at 100km/h need approximately 32 car lengths to safely stop.

Drivers are reminded to keep a safe distance behind other vehicles at all times and not to cut in front of heavy vehicles which require much longer braking distances.

If drivers need to travel below the speed limit, they are encouraged to drive in the left-hand lanes to improve traffic flow by allowing trucks and other vehicles to travel at the speed limit without changing lanes. 

How will we evaluate the trial?

We will evaluate the success of the Trial by:

  • analysing the number of recorded crashes and incidents
  • level of tailgating 
  • travel efficiency
  • feedback from stakeholders and the community
  • environmental impacts such as noise and pollutions

The results of the trial will also provide information to assist in future heavy vehicle policies for urban areas in Victoria.

What is Stage 2 of the Monash Truck Trial?

Stage 2 of the Monash Truck Trial is a ban on trucks in the far right hand lane on the Monash Freeway and follows on from Stage 1 of the trial.

What happened in Stage 1 of the Trial?

Stage 1 was a trial to reduce the speed of trucks to 90km/h between Huntingdale Road and Jacksons Road. The trial was concluded in early March as traffic data indicated that there was increased tailgating and weaving between trucks and cars. Feedback from motorists on engageVicRoads (VicRoads engagement platform) about their experience also indicated that driver aggression and tailgating increased.

What is the overall purpose of the trial?

The overall purpose of the trial to ban trucks in the far right hand lane is to explore ways to increase safety for Monash Freeway road users.

Are trucks causing all of the accidents on the Monash?

No, this trial as for the Stage 1 trial, does not place blame on trucks for the volume of crashes on the Monash. It is the responsibility of all road users to share and use the road in a safe manner.

What is defined as a truck and will buses be included as part of the trial?

For the purpose of the trial a truck is a vehicle that weighs in excess of GVM 4.5 tonnes. Buses will not be included as part of the trial.

Why is the ban being trialled on the Monash Freeway chosen?  

The Monash Freeway is unique because it’s one of Victoria’s biggest freight routes with over 200,000 vehicles driving along it every day, 40,000 of those being heavy vehicles. Heavy vehicles have been over represented in the number of crashes on the Monash Freeway and as a result we are hoping to improve safety through the trail on the Monash.

Where is the trial taking place?

The trial is taking place in the same corridor as Stage 1; between Huntingdale Road, Mount Waverley and Jacksons Road, Mulgrave on the Monash Freeway inbound and outbound.

Will the trial clash with the Monash Freeway Upgrades?

The Monash Freeway Upgrades will not clash with the trial as the trial involves a ban for trucks only in the far right hand lane. If the upgrades render the far right hand lane unusable in the trial area, trucks will have complete access to all other lanes of the Monash.

How will you evaluate the success of the trial?

We will evaluate the success of the trial through real time data collection that will analysing the number of crashes and incidents in the trial area, the level of tailgating occurring, and the presence of trucks in the far right hand lane, travel efficiency and feedback from stakeholders and the community. The ARRB is the independent body evaluating the trial
