Compliance is region-specific. For the European market, vehicles must meet Euro 6 emission standards and possess WVTA (Whole Vehicle Type Approval) or CE certification. For the US market, adherence to DOT (Department of Transportation) and EPA (Environmental Protection Agency) standards is required. Ensure the supplier provides crash test ratings (such as CNCAP, Euro NCAP, or IIHS) and verifies the presence of Active Safety Systems like AEB (Autonomous Emergency Braking), LKA (Lane Keep Assist), and TPMS (Tire Pressure Monitoring System).
