A 3-minute lesson from the Alabama course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Mufflers: every vehicle needs a muffler in good working order that eliminates excessive or unusual noise, such as sharp popping or cracking. Muffler cutouts, bypasses and similar devices are forbidden.
A horn in good working order is required. Use it only to give warning when reasonably necessary for safety, never to announce your arrival or call passengers. Needless use can lead to arrest.
Your friend installed a muffler bypass so the car pops and cracks. That's forbidden: the muffler must eliminate that kind of noise. And honking to tell a friend you've arrived is unlawful horn use.
