Singapore regulations & registration
LTA (Land Transport Authority)
The Land Transport Authority (LTA) is the Singapore statutory board that regulates road vehicle standards, including window tint Visible Light Transmission rules.
The LTA sets and enforces vehicle compliance standards under the Road Traffic Act. Window tint rules are part of vehicle modification regulations, with the agency setting VLT minima and inspecting at VICOM, JIC and STAI authorised centres.
The current rules: front windscreen ≥70% combined VLT, side windows ≥25%, rear windows ≥25%. Excessive reflectivity (mirror tint) is also prohibited.
The LTA's regulations exist for road safety — windshield visibility, especially at night and during heavy rain. A workshop that knows the rules will refuse to install non-compliant films on the windscreen.
