When we hear a loud sound that goes like "wee-woo, wee-woo," it's the siren of a fire truck! This sound is really important because it tells us that the fire truck is coming quickly to help. The fire truck also has flashing lights that may be red or blue. These lights blink brightly to get everyone's attention, kind of like a super cool disco party!
Firefighters need to get to places fast, like if there’s a fire or someone is in trouble. The siren and lights help clear the way so other cars know to move aside. That way, the fire truck can zoom through safely. So, when you hear that loud sound and see the flashing lights, you know heroes are on the way to help!
