About:Why are fire trucks red? why are they red you ask? well then, I'l tell you why. You see my boy, fire trucks have 4 wheels and 8 men. 4 + 8 is 12. You see, there are 12 inches in a ruler, Queen Elizabeth II was a ruler, she also was a boat, boats sail in the sea, and there are fishes in the sea. Fishes have fins, the fins fought the russians, and of corse the russians wore red. Fire trucks are always a rushin' so that is why fire trucks are red.
