To enhance road safety, the Ministry of Transportation and Communications (MOTC) has revised relevant regulations and established a window tint transmittance management system. In the future, cars with window tints will be subject to clearer transmittance standards and product management systems.
This article will comprehensively cover:

Allowing car owners to understand the latest policies all at once.
I. When will the window tint regulations take effect?
According to the MOTC announcement, the new window tint transmittance system will officially be implemented on February 28, 2026 (February 28, 2026). By amending the "Road Traffic Safety Rules," automotive window tints will officially be brought under the scope of management.
Main applicable objects of the new system:
- New cars first registered after February 28, 2026
- New car registration inspections and subsequent periodic vehicle inspections
- Subsequent periodic vehicle inspection system
Currently, the policy adopts the principle of non-retroactivity, so cars that have already been registered are not currently forced to replace their window tints.

III. Do old cars need to replace their window tints according to the regulations?
Currently, the policy is: old cars are not subject to retroactive application. This means that cars already on the road temporarily do not need to replace their window tints.
However, changes may still occur in the future, and the government may consider gradually incorporating old cars into the management.
Therefore, the industry and car owners generally recommend: When replacing window tints in the future, directly choose products that comply with the new regulations.

According to MOTC regulations, compliant window tints must have a product mark.
There are two marking methods:
1️⃣ Supplier self-embossed watermark mark

What happens if window tints do not comply with regulations? Common violations and handling methods at a glance
If car owners fail to complete improvements and re-inspections within the stipulated period, they may face penalties such as fines, license plate suspension, or even license plate cancellation.
Below, the editor has compiled several common situations and possible outcomes:
1. Failure to participate in vehicle inspection as required
Penalties usually range from NT$900 to NT$1,800 in fines.
Car owners are advised to complete the inspection within the deadline after receiving the inspection notice to avoid unnecessary fines.
2. Inspection overdue by more than one month
If the vehicle has not completed inspection more than one month after notification, the supervisory authority may take stricter measures, including suspension of the vehicle license plate.
The license plate will only be returned after the inspection is completed and confirmed to be compliant, so car owners are advised to arrange the inspection as soon as possible.
3. Inspection overdue by more than six months
If the vehicle has not completed inspection for more than six months, the supervisory authority may further cancel the license plate.
4. Inspection failed but not improved within the deadline
If the vehicle inspection result is non-compliant (e.g., window tint transmittance does not meet regulations), the car owner must complete repairs and apply for re-inspection within 1 month.
Failure to improve and re-inspect within the deadline may result in:
- License plate suspension
- And a maximum fine of NT$1,800
Therefore, car owners are advised to deal with non-compliant inspections as soon as possible and arrange for re-inspection.
5. Re-inspection still not passed
If the vehicle applies for re-inspection after repairs, but still does not meet the standards, the supervisory authority may still continue to suspend the license plate.
At this point, the car owner must repair the vehicle's deficiencies again and reapply for re-inspection until it complies with regulations.
⚠️ Reminder:
The above information is compiled based on publicly available data from current transportation authorities. Actual implementation should still be based on the latest announced laws and regulations of the supervisory authorities.
