The short answer
Malaysia’s Road Transport Department (JPJ) sets a minimum VLT, visible light transmission, for each window. That is how much light must still come through the glass with the film on.
At least 70% of light must pass
Driver and front passenger: at least 50% of light must pass
Any shade, with side mirrors on both sides
70% does not mean 70% dark
The JPJ number is the light that gets through, not how dark the film is. A 70% windscreen film lets 70% of the light in, so it is only 30% dark. A 50% front window film is half dark. Many people read it the other way round and fit a film that is too dark.
Dark is not the same as cool
How much heat a film keeps out is a separate number, IRR (infrared rejection). A film that passes the JPJ limits can still reject a lot of the sun’s heat. At our shop, Carbon HD rejects about 74% of infrared heat, Nano US Diamond Ceramic about 96% and Nano Ceramic Carbon HD about 99%, and all three stop 99–100% of UV.
If a window is too dark
The limits come from the Motor Vehicles (Prohibition of Certain Types of Glass) Rules 1991, amended in 2019. JPJ has said that breaking them can bring a fine of up to RM2,000 or up to six months in jail. A second or later offence can bring a fine of up to RM4,000 or up to 12 months in jail, or both.
Darker for health or safety
If you need darker windows for a health or safety reason, you can apply to JPJ for a permit, by post or through the JPJ portal at jpj.gov.my. Until the permit is approved, the normal limits apply.
