The actual rules
Five things to understand.
QLD window tint law is governed by the Transport Operations Vehicle Standards and Safety Regulation, which adopts Australian Design Rule (ADR) 8/01 for windscreen visibility plus state-specific rules for side and rear glass. Here's what those rules actually say.
01
VLT measures combined transmission
VLT (Visible Light Transmission) is the percentage of visible light that passes through the glass and film together, measured at the assembled window. A 35% film on a factory-tinted rear window will measure lower than 35% combined. That combined figure is what counts at inspection, not the film percentage in isolation.
02
Windscreen: top visor band only
No tint across the main viewing area of the windscreen. Tint film is allowed only in the top 10% of the windscreen or above the swept area of the wiper blades, whichever is lower. This is the "visor band" you see on some cars. The rest of the windscreen must meet the factory clear glass standard for visibility.
03
Front side windows: 35% minimum VLT
Driver and front-passenger side windows can be tinted down to 35% VLT (combined film + factory glass). Most factory front side glass is around 70-80% clear, so a 35% film usually lands the combined figure right around 35%. Run a darker film than that on the fronts and you fail inspection.
04
Rear side + rear windscreen: no QLD minimum
This is where QLD differs from most other states. Windows behind the driver in a passenger vehicle can be tinted to any darkness. NSW and Victoria specify minimums (around 20% VLT) for rear glass. QLD does not, for cars used purely for personal transport. Limousines and a few other vehicle classes have separate rules.
05
What gets you defected
Front side windows tinted darker than 35% VLT. Windscreen tint extending below the legal visor band. Bubbled or peeling film that obscures vision. Mirror-finish or reflective tint above certain reflectivity thresholds. At a road-worthy inspection or a roadside check, an inspector uses a portable VLT meter on the side windows. If the reading is under 35% VLT on the fronts, the vehicle gets a defect notice and you remove and re-fit before re-inspection.
