In the United States, the United Kingdom, and Australia, you should contact the respective government agencies (such as the DMV in the US, the DVLA in the UK, and the relevant authority like RMS in New South Wales or TMR in Queensland in Australia) for vehicle modifications that affect vehicle registration, safety, or other aspects. These modifications may include:
Changes in the vehicle category: For example, converting a passenger car into a camper.
Alterations in vehicle dimensions or weight: Adjustments causing significant changes in the vehicle's size or weight.
Modifications affecting vehicle safety: Such as major structural changes or adjustments to safety features.
Modifications affecting emissions: If the changes you make lead to alterations in the vehicle's emissions.
It's important to note that these regulations generally do not apply to our products, as they do not directly impact the mentioned aspects. The exact procedures and requirements vary from country to country and even from state to state in some cases. Therefore, it is advisable to contact the relevant government agency in your specific region for accurate information regarding vehicle modifications and approvals.
