What must be inspected on every Passenger Car and Motorhome under 80 inches wide?

The inspection of every Passenger Car and Motorhome under 80 inches wide includes a comprehensive evaluation of various critical components to ensure the vehicle's safety and compliance with regulations. Each item listed plays a significant role in the overall functionality and safety of the vehicle.

Brakes and tires are essential for the safe operation of any vehicle. The brakes must be inspected for their effectiveness and condition, as faulty brakes can lead to dangerous situations. Tires must be checked for adequate tread depth and proper inflation, which are crucial for traction and handling.

The horn and windshield wipers contribute to the vehicle's operational safety as well. A functioning horn is necessary for communication with other road users, particularly in emergency situations, while operational windshield wipers are vital for maintaining visibility in adverse weather conditions.

The exhaust system and the Vehicle Identification Number (VIN) are also critical components to inspect. The exhaust system must be checked for leaks and proper operation to reduce harmful emissions, contributing to environmental safety. The VIN is important for identification and registration purposes, ensuring that the vehicle is not stolen or has outstanding issues.

Since all these components must be inspected to ensure the vehicle meets safety standards, the correct answer reflects the necessity of a thorough inspection covering every aspect of vehicle operation and compliance.
