Yes, that’s a fire truck and yes it’s pulling up to my house. I was making pizza in the oven and suddenly all the smoke detectors in the house went off. I figured it was the oven, but called the FD just in case. Everything was fine, and the firemen were very professional and I’m glad they showed up. The problem: My house’s smoke detectors were old, out-of-date actually. I replaced them all and haven’t had a problem since.
