The Mornington Peninsula Speed Limit Change Trial revealed some pretty important stuff: people overwhelmingly support safer and more appropriate speed limits when they align with community needs and deliver tangible benefits. In this case it was a lot of roads reduced from the default 100km/h to 80km/h.


What the Data Shows About Community Sentiment:
Strong Compliance Over Time:
Over 60% of drivers adjusted to the new 80 km/h limits.
Compliance continued to improve across the trial periods, demonstrating that communities adapt when limits feel reasonable and are clearly communicated.

Support for Safety Improvements:
Community acceptance of safer speed limits grew as the tangible benefits, such as fewer crashes and improved safety, became evident.
With an estimated 20% reduction in fatal and serious injury crashes, local residents began to see the value in prioritising human life over speed.

Alignment with Local Needs:
The trial routes were carefully selected to reflect the unique characteristics of Mornington Peninsula roads, many of which serve both locals and visitors.
By focusing on roads with higher risk that also felt unsafe at higher speeds, the changes resonated with the lived experiences of the community.

Lasting Cultural Shift:
Communities embraced safer speeds as part of a broader shift towards prioritising health, safety, and sustainability.

What does this mean?
This trial reinforces that communities value safer roads and will embrace speed limit changes when they are thoughtfully implemented. By aligning with the needs of residents and visitors, Mornington Peninsula has set an example of how community-driven safety initiatives can succeed.
