Rear Window 25% VLT Rule
The LTA requires that rear side and rear windscreen windows maintain at least 25% combined VLT; many vehicles already have privacy glass at this level from the factory.
OEM "privacy glass" on SUVs and MPVs often comes from the factory at 20–40% VLT. Adding aftermarket film over OEM privacy glass requires care to maintain the legal minimum.
Vehicles with light OEM rear glass can accept darker aftermarket film — sometimes down to 35–40% VLT.
VICOM checks all four side windows plus the rear windscreen at inspection. Tinting workshops with calibration meters can predict VLT before installation to avoid compliance surprises.
