4.1 Lane Filtering and Edge Filtering: Two Different Queensland Rules

Lane Filtering and Edge Filtering

Queensland permits two carefully limited practices for experienced open-licence motorcycle riders. Lane filtering occurs between lines of traffic. Edge filtering occurs on a sealed road shoulder or emergency stopping lane. Mixing the conditions for the two rules produces wrong answers.

Eligibility shared by both rules

The rider must hold an open licence for the motorcycle being ridden. An RE learner, a provisional motorcycle holder and a person learning to ride class R on an RE licence cannot filter. The manoeuvre must be safe and the rider’s speed must not exceed 30 km/h.

The speed limit is a maximum, not a target. A gap may be unsafe well below 30 km/h because of mirrors, doors, pedestrians, cyclists, buses, trucks, lane changes or a narrowing space. An eligible rider must be able to merge back into traffic safely.

Lane filtering

Lane filtering means riding at low speed between stationary or slow-moving vehicles travelling in the same direction. The two lines or lanes must both travel in that same direction.

An open rider must not lane filter:

• above 30 km/h;
• in a school zone during the school-zone hours shown on the sign;
• if a “no filtering” sign applies;
• through a dedicated left- or right-turning lane;
• in a bicycle lane;
• between a vehicle and the kerb; or
• whenever the available gap, visibility or behaviour of other road users makes it unsafe.

Filtering beside parked vehicles or large vehicles is particularly hazardous because of doors, pedestrians and blind spots. TMR advises riders not to filter near trucks or buses. That is a safety application of the general “safe to do so” requirement, not permission to ignore an express prohibition elsewhere.

The phrase “lane splitting” is often used for riding between moving traffic at higher speeds. Queensland’s permission stops at 30 km/h; a rider cannot turn an over-30 manoeuvre into legal filtering by describing traffic as slow.

Edge filtering on a shoulder

An open rider may pass stationary or slow traffic on a sealed road shoulder or emergency stopping lane when:

• the road’s speed limit is normally 90 km/h or more;
• the motorcycle travels at 30 km/h or less;
• the rider gives way to bicycle riders or motorcycle riders already using the shoulder;
• the rider stays off unsealed parts;
• there are no roadworks;
• the location is not a tunnel; and
• the manoeuvre is safe.

A variable speed sign may temporarily reduce the displayed limit on a road normally limited to at least 90 km/h. TMR says edge filtering remains permitted under the rule when the normal limit qualifies. This is different from a road whose ordinary limit is below 90.

It is therefore false to say that motorcycles may never ride on a shoulder. It is also false to apply the shoulder permission to any urban road. The open-licence, normal-road-speed, 30 km/h, sealed-surface and location conditions must all be present.

Bicycle storage areas and bicycle lanes

A bicycle storage area is the marked waiting box at traffic lights. A motorcycle rider may enter it if they give way to bicycle riders and motorcycle riders already there. The permission to enter a storage area does not permit lane filtering in a bicycle lane. Outside filtering, a motorcycle may use a bicycle lane for only the limited general-rule purposes and distance stated in Queensland road rules, such as entering or leaving the road, overtaking a right-turning vehicle or avoiding an obstruction.

A decision sequence

For every filtering question:

1. Identify the motorcycle-licence type. If it is learner or provisional, stop: no filtering.
2. Identify the path: between same-direction traffic is lane filtering; beyond an edge line is edge filtering.
3. Check speed—30 km/h or less.
4. For lane filtering, check school-zone hours, turning lanes, bicycle lanes, kerb, signs and safety.
5. For edge filtering, check the road’s normal limit, sealed surface, roadworks, tunnel and users already on the shoulder.

The two rules share eligibility and speed but have different place-based conditions. Before either manoeuvre, check mirrors and the relevant blind spot, identify a safe place to rejoin traffic and keep enough side clearance for a door, mirror or sudden lane change. Do not filter merely because another rider does. Their licence, speed, view and available gap may differ. If any condition is uncertain, remain in the traffic lane with the normal crash-avoidance space.
