This question comes up constantly in DFW neighborhood groups, especially around holidays. Here's how to tell.
Sound differences:
- Gunshots: Sharp, short, consistent volume. Rapid succession if semi-auto. Single loud crack if shotgun/rifle. No echo pattern — just a flat "pop" or "crack."
- Fireworks: Variable volume, often with a whistle or hiss before the bang. Longer duration per event. Crackle/sizzle after the boom. Multiple different sounds in sequence.
Pattern differences:
- Gunshots: Usually 1-8 rapid-fire shots, then silence. May be followed by tire screeching or yelling.
- Fireworks: Prolonged display lasting minutes. Multiple types of explosions. Often visible in the sky.
When to call 911:
- If you hear what sounds like gunshots, ALWAYS call. Let dispatch determine if it's fireworks.
- If you hear screaming, glass breaking, or tire screeching with the sounds, call immediately.
- You don't need to be certain. "I heard what sounded like gunshots" is enough.
ShotSpotter coverage: DPD has ShotSpotter acoustic sensors in parts of South Dallas, Pleasant Grove, and Oak Cliff. These automatically detect and locate gunfire and alert police. You should still call 911 — ShotSpotter doesn't cover all areas.

When in doubt, call. Dispatchers would rather get 10 fireworks calls than miss one shooting.
