Which statement is true regarding the condition of a vehicle's muffler?

• A. A muffler is optional for all vehicles
• B. A vehicle is required to have a working muffler
• C. A muffler must always be removed during daylight
• D. A vehicle can operate without a muffler if it's allowed

Answer: (B)

A vehicle is required to have a working muffler because it plays a crucial role in controlling the noise produced by the engine and reducing harmful emissions. Most jurisdictions have laws and regulations in place that mandate the presence of a functioning muffler to ensure that vehicles comply with noise level standards and environmental regulations. The muffler not only contributes to a quieter operation but also helps improve the overall efficiency of the exhaust system by directing exhaust gases safely away from the engine and cabin area. While some vehicles may theoretically operate without a muffler, doing so is generally against regulations that govern vehicle emissions and noise, making option B the only accurate statement regarding the necessity of a working muffler in most cases.
