Based on the IMDG Code - Special Provisions 961, regular passenger vehicles or any other product with a combustion engine are NOT regarded as a hazardous cargo when loaded on Ro/Ro(Roll-on/Roll-off) vessels.

Important notice: For carrying such products inside a container, it will still be considered hazardous cargo (UN 3166, Class 9) unless a number of conditions can be met. Some of which may be technically very difficult to comply with.
