Australian Road Signs and Traffic Signals: Official 2026 AS 1742 & Motorway Guide

Under Australian Standards AS 1742 (Manual of Uniform Traffic Control Devices) and state Road Rules, road signs are grouped into 5 primary categories: 1. Regulatory Signs (R-series): Compulsory instructions or prohibitions (Stop R1-1, Give Way R1-2, Speed Disc R4-1, Keep Left R2-3, No U-turn R2-15); 2. Warning Signs (W-series): Yellow diamond hazard alerts (Curves, T-intersections, pedestrian crossings, animal hazards); 3. Guide & Route Signs (G-series): Alpha-numeric route shields (M, A, B motorway/highway designations), exit destinations, and tourist brown signs; 4. Temporary / Roadwork Signs (T-series): High-visibility yellow/orange diamond and rectangular work zone signs; and 5. Road Surface Markings: Continuous dividing lines, broken dividing lines, edge lines, pedestrian zebra stripes, and lane arrows.

Under Australian Road Rules ARR 67 and 69: At an octagonal Stop sign (R1-1), your vehicle must come to a complete, standstill stop behind the solid white stop line before entering the intersection, even if the road is completely empty. At an inverted triangular Give Way sign (R1-2), you must slow down and give way to all vehicles travelling on, entering, or turning across the intersecting road; you only need to come to a full stop if required to yield safely.

In Australian road signage, circular signs with a bold red outer border are Regulatory Prohibitory or Limitation Signs (such as R4-1 Speed Limit signs, R2-15 No U-turn, or R2-6 No Entry). Under Australian Road Rules, disobeying any regulatory sign is an offence carrying heavy statutory fines and demerit points against your learner permit or provisional licence.

On Australian motorways and freeways (designated with green M-series route shields and freeway entry signs): 1. Under ARR Rule 130, on multi-lane roads with a speed limit over 80 km/h (or where 'Keep Left Unless Overtaking' signs apply), you must keep left unless overtaking, turning right, or driving in congested traffic; 2. Stopping or parking on the freeway carriageway or road shoulder is strictly prohibited except in emergency stopping bays or breakdowns; 3. Pedestrians, bicycles, mopeds/low-powered scooters, and animal-drawn vehicles are prohibited; 4. U-turns across motorway median strips or emergency crossovers are illegal.

Under ARR Rules 56-61: A Red light requires a full stop behind the stop line. A Yellow (Amber) light means stop unless you are so close to the stop line that stopping cannot be done safely. A Green light permits proceeding straight through or turning if clear, yielding to oncoming traffic and crossing pedestrians. A white 'B' light (B-signal) regulates public buses only, and a white 'T' light regulates trams only (general drivers must NOT proceed if vehicle lights are red even if B or T signals are lit). A Flashing Yellow light indicates signals are blacked out or in caution mode; drivers must apply standard give-way and roundabout priority rules as if it were an uncontrolled intersection.

Under ARR Rule 132: A single continuous (solid) dividing line or a double continuous dividing line means you must NOT cross or straddle the line to overtake or perform a U-turn. You may only cross a single continuous line to enter or leave the road (e.g. turning into a driveway or side street) or to pass an obstruction or safely overtake a cyclist (maintaining minimum 1.0m clearance under 60 km/h or 1.5m over 60 km/h) if safe to do so. Crossing double unbroken lines for overtaking or U-turns is strictly prohibited across all Australian states.

In Australian states (such as NSW Service NSW DKT, QLD PrepL, VIC VicRoads Permit, and WA DoT), the knowledge exam consists of 30 to 45 questions split into two main sections: General Knowledge & Road Signs and Road Safety / Priority Rules. You generally must answer at least 41 out of 45 correctly (91%+) in NSW, with a mandatory 100% pass requirement on critical road safety and speed questions. Our simulator calibrates practice tests to the exact pass marks of all 8 Australian jurisdictions.
