p50 traffic jam is a period-50 oscillator discovered by Noam Elkies on October 16, 1994. It works by hassling the 25-generation traffic jam reaction with two copies of fumarole and two copies of octagon 2. In terms of its 92 cells, it was the smallest known period-50 oscillator until May 2022, when the LCM oscillator 24P10 on 30P25 was found. The version shown is the cis version, and by reflecting the right side it is possible to get a trans version with also 92 cells.

The traffic jam reaction gives off strong dot and obo! sparks. An example of the p50 traffic jam being used as a sparker, although at the generation before the spark, is shown below. Another example, but at a different period, is mentioned on the p44 traffic light hassler page. The period-50 glider gun used the p50 traffic jam in a different way before the much smaller 55P10 was discovered.
