A large truck driving by as an emergency siren wails and truck horn honks
A wailing siren fades, a motor sputters, then the siren resumes accompanied by blaring horns
An emergency siren ringing with car horn honking
A fire truck engine runs and the siren is blowing but stops, traffic is present, the fire truck horn honks twice, and the siren begins again
A fire engine with a siren fading then another loud siren
