Which of the following items is checked for compliance during a Class D inspection?

During a Class D inspection, one of the crucial items checked for compliance is tire tread depth. This aspect is essential because adequate tire tread depth is vital for vehicle safety. It directly affects traction, handling, and stopping distances, especially in wet or slippery conditions. Inspectors measure the tread depth to ensure that it meets the minimum legal requirements and is safe for road use.

Other items such as paint color, alternative fuel systems, and window tint percentage may not be part of the standard compliance checks during a Class D inspection. Ensuring proper tire safety is a fundamental aspect of maintaining vehicle operability and safety on the road, making it a priority during inspections.
