TAIPEI (Taiwan News) — The Ministry of Transportation and Communications (MOTC) will announce new safety guidelines on automotive window tint transparency by the end of June.

During a legislative review of proposed amendments to the Highway Act on Monday, KMT Legislator Hung Mong-kai (洪孟楷) criticized the lack of mandatory standards for window tinting in Taiwan. He noted that while countries such as the US, Japan, and Germany enforce clear rules, Taiwan has no regulations, inspection tools, or standards for older vehicles, per CNA.

Deputy Transportation Minister Chen Yan-po (陳彥伯) said window film use raises safety concerns. He said the Highway Bureau has drafted guidelines based on Taiwan’s road conditions and public safety needs, which will apply to both new and existing vehicles.

The ministry will publish the guidelines in June, with enforcement for new vehicles to begin next year. Non-compliant vehicles will face penalties, and the transparency standards will be incorporated into formal regulations.

Hung said that unless the new rules apply to all vehicles, enforcement would be ineffective. He stressed that penalties should be extended to existing vehicles to ensure consistency and compliance.

Highway Bureau Director-General Chen Wen-juei (陳文瑞) said the rollout will begin with public awareness campaigns following the release of the safety guidelines. Regulations will be formally amended next year, when enforcement for new vehicles becomes mandatory.

Chen said the guidelines will specify transparency standards, applicable window areas—such as the front windshield, front and rear side windows, and rear windshield—and related penalties.

Vehicles must meet the new standards during inspection after tinting. If a vehicle fails, owners must make corrections. Failure to comply will result in continued follow-up and fines.

For existing vehicles, Chen said a sunset clause will be introduced, but the exact timeline will be determined during the legislative amendment process.
