What type of market should vehicles belong to for emissions testing to proceed normally?

The gray market refers to the trade of goods through unauthorized but legal channels. In the context of emissions testing, vehicles from the gray market can present unique challenges. These vehicles may be imported or distributed outside of the official manufacturer or dealer networks, leading to complications with compliance to emissions standards. Testing these vehicles might require additional scrutiny or may not align with local regulations, rendering emissions testing more complicated.

In contrast, an open market typically features full compliance with regulations and allows for straightforward emissions testing, while the luxury market specifically targets high-end vehicles, which may or may not fit regular testing protocols based on their unique designs and emissions standards. The used market is focused on pre-owned vehicles which can vary significantly in emissions depending on their condition and age.

Understanding that gray market vehicles might not conform to standard emissions regulations helps clarify why this type does not provide a straightforward testing environment.
