California Air Resources Board

California must transition to zero and near-zero emission transportation and freight movement technologies to meet its air quality and climate goals. However, CARB's comprehensive heavy-duty engine and vehicle certification requirements may deter some manufacturers from developing promising new heavy-duty vehicle technologies, in part because of high initial certification costs and engineering challenges. To address these challenges and encourage additional needed technology innovation, the Innovative Technology Regulation provides a more flexible short-term certification pathway for innovative truck and bus technologies.
