What is VLT in Car Tint Film?

Tinted windows are one of the most popular upgrades for cars in Malaysia. They reduce heat, block harmful UV rays, and add privacy. But there’s one term that keeps showing up whenever JPJ rules are mentioned: VLT.

What is VLT in Car Tint Film?

So, what exactly is VLT, why does it matter, and how does it affect the tint film you choose?

Meaning of VLT (Visible Light Transmission)

VLT stands for Visible Light Transmission. It tells you how much visible light can pass through your car window.

  • A high VLT means more light passes through, so the glass looks brighter.
  • A low VLT means less light passes through, so the glass looks darker.

Example:

  • 70% VLT = 70% of light comes through, 30% is blocked.
  • 30% VLT = only 30% of light passes through, so the window looks very dark.

Why VLT is Important

  1. Legal compliance – JPJ uses VLT to decide if your tint is legal or not.
  2. Safety – overly dark tints reduce visibility, especially at night or in bad weather.
  3. Comfort – the right VLT can block glare and heat but still give you clear vision.
  4. Car value – a JPJ-compliant tint prevents problems during roadblocks or resale.

JPJ Tinting Rules 2025 (VLT Requirements)

  • Front windscreen: Minimum 70% VLT.
  • Front side windows (driver & passenger): Minimum 50% VLT.
  • Rear side windows & rear windscreen: No minimum limit, as long as the car has both side mirrors.

How VLT is Measured

JPJ and inspection centers use a device called a VLT meter.

  • The meter clips onto the window and gives a percentage reading.
  • The reading is based on the combined effect of factory glass + tint film, not the film alone.
  • That means if your car already comes with slightly tinted factory glass, adding a dark film could push the reading below the legal limit.

What Happens if You Don’t Comply

  • First offence: Fine up to RM2,000 or 6 months in jail, or both.
  • Repeat offences: Fine up to RM4,000 or 12 months in jail, or both.

In many cases, JPJ may also require you to remove the illegal tint immediately.

Choosing the Right Tint Film

  1. Ask the installer to test VLT with a certified meter before and after installation.

  2. Choose a film that balances comfort and legality – not too dark on the front.

  3. Keep your receipt and tint specifications as proof.

  4. If you need a darker tint for medical or security reasons, apply officially to JPJ for exemption instead of taking risks.

VLT isn’t just a technical term – it’s the deciding factor that tells you whether your car tint is legal or illegal. To avoid fines, keep your front windscreen at 70% VLT and front side windows at 50% VLT. You have more freedom at the back, but don’t be fooled by “approved” stickers or marketing claims.

With the right film and the right VLT, you’ll enjoy comfort, protection, and peace of mind on the road.
