Singapore regulations & registration

Side Window 25% VLT Rule

The LTA requires that side windows of Singapore-registered vehicles maintain at least 25% combined Visible Light Transmission, allowing more darkness than the front windscreen.

The 25% side-window rule gives Singapore drivers room for meaningful privacy and heat rejection. Most quality ceramic films come in 30–50% VLT options that comfortably pass.

We typically recommend 30–40% VLT on the side windows as a sweet spot: dark enough to deter casual exterior view, light enough for safe night-time visibility when reversing.

VICOM measures side-window VLT on inspection. Quality workshops measure pre-release as part of the QC process.
