Have you ever been sitting in traffic, only to see a motorcycle zip between your car and the one next to you? You’re not alone. Many senior drivers find this behaviour confusing—even alarming.
This is called lane filtering, and in South Australia, it’s legal under certain conditions.
Let’s explain what you need to know to stay safe and calm on the road.
What Is Lane Filtering?
Lane filtering is when a motorcycle rides between stationary or slow-moving vehicles going in the same direction, usually in traffic jams or at red lights.
It’s not the same as overtaking — it only happens at low speeds (under 30 km/h) and is done by fully licensed motorcycle riders.
Why Is Lane Filtering Allowed?
South Australia legalised lane filtering in 2017. The goal is to:
What Should Senior Drivers Know?
- Reduce traffic congestion
- Allow motorcycles to get through safely in heavy traffic
- Minimise rear-end crashes involving motorcycles
If you’re over 60 and have decades of driving experience, this rule may feel strange or unsafe. Here’s what’s important:
- It’s legal: If the motorcycle is moving slowly and you’re stopped or crawling, don’t be alarmed if it passes between lanes.
- Don’t move unexpectedly: Stay in your lane and check mirrors carefully before changing lanes or opening doors.
- Be patient: Lane filtering is not aggressive driving. Most riders are trained and following the law.
- Look twice: Before turning or merging, especially in traffic, always check mirrors and blind spots.
Where Lane Filtering Is NOT Allowed
Even licensed motorcyclists can’t filter just anywhere. They are not allowed to filter:
- In school zones during active hours
- On roundabouts
- Next to parked cars
- In bus or bicycle lanes
- If traffic is moving faster than 30 km/h
Why Does This Matter to You?
Understanding lane filtering helps:
- Reduce road rage or misunderstandings
- Avoid accidental collisions
- Improve your awareness of vulnerable road users
Final Tip for Senior Drivers
As we age, our reaction times may slow and peripheral vision may weaken. That’s why it’s more important than ever to stay alert, avoid distractions, and expect motorcycles to appear in unexpected places—especially in traffic.
Staying calm and aware is the best way to share the road safely.
