p50 traffic jam is a period-50 oscillator discovered by Noam Elkies on October 16, 1994.[1] 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.[2] 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.
