China Proposes Rules for Pop-Top Vehicle Cabins

China's Ministry of Industry and Information Technology (MIIT), in conjunction with the Ministry of Public Security, the Ministry of Ecology and Environment, and the State Administration for Market Regulation, has drafted new regulations for vehicles incorporating pop-top cabin structures. These proposed rules aim to enhance safety and manage innovative vehicle designs.

The draft mandates that pop-top cabin structures must meet existing standards, such as GB26134 for passenger car roof compression strength. Additionally, manufacturers will need to conduct comprehensive safety assessments, including evaluations for anti-pinch safety, crashworthiness, and wind resistance, alongside a thorough risk analysis of usage scenarios.

A key provision in the draft requires automotive companies to implement technical limitations preventing the use of the pop-top function while the vehicle is in motion. This measure is intended to mitigate potential accidents associated with operating the elevated cabin during driving.

Set to take effect from January 1, 2027, the regulations will require new product applications featuring innovative designs to include technical parameters for these innovations and undergo rigorous safety and environmental assessments according to new guidelines. Products failing to meet these testing and reporting requirements will not be approved for market.
