If you have an ASL video of the "Stop the Traffic" story and need a written translation, follow this professional protocol:
The "translation" here is not of words, but of physics. The signer must convey the speed of the car. This is not done by signing "FAST." Instead, it is done through the intensity of the classifier movement (the "vehicle" classifier, usually a "3" handshape). A slow car wobbles; a fast car zooms with tension. The translation of the moment requires the signer to become the car, adopting the non-manual markers (facial expressions) of a driver who is panicked or aggressive.
The pedestrian walks confidently across. The signer’s eyes track the "cars" waiting patiently. The final sign is often a satisfied nod or wiping sweat from the brow, indicating relief.
Shift your body slightly to represent the man’s perspective versus the perspective of a driver looking up at him.
