A study on automotive tint glazing in Malaysia

The level of Visible Light Transmission (VLT) for front windscreen and other windows of vehicles have not been reviewed since its first implementation in Malaysia. The Ministry of Transport (MOT) has taken the initiative through its formalized committee to review the relevancy of existing VLT specifications, propose recommendations and acquire feedbacks from related stakeholders and consumers through a two-day seminar which was held from 2nd to 3rd June 2014. As part of the committee, MIROS was given the responsibility to review the effects of window tinting on driver’s visual performance and thermal comfort, gauge the public perception on the usage of window tinting and existing law in Malaysia, and investigate the current scenario of VLT compliance on the ground. Overall, reducing the level of VLT (darker tinting) may affect the visual performance particularly for older drivers, but have minimal effect in reducing the cabin temperature as infrared rejection plays a more significant role than VLT in reducing the heat penetration into the vehicle. Though most of the surveyed respondents had their vehicles tinted, knowledge on existing law in terms of allowable VLT specification and amount of fine if violated was very low. Apart from that, most of the volunteered vehicles inspected for VLT compliance did not comply with the existing VLT specification. Further observation revealed that there might be some misinterpretations by the tinted shops and consumers on the final VLT value when the tinted film is attached onto the existing glasses which already have built-in VLT level. After taking into consideration all the findings, potential recommendations are proposed at the end of this report for consideration by the related authorities.
