🎤Pronunciation
🌳Etymology
Origin
This phrasal expression emerged in the early 20th century with the introduction of traffic signals. It combines 'run' (meaning to pass through) with 'red light' (denoting the stop signal), creating an idiomatic phrase that vividly depicts the action of passing through a red traffic light as if rushing or speeding past it.
Breakdown
run (pass through or proceed) + red light (the red traffic signal indicating stop). The phrase anthropomorphizes the traffic light as an obstacle to be rushed past rather than obeyed.
