Afaik it could be sold in the US just fine (this is a car created in 1948, safety regulations were not really a thing).
The issue is that it could not be sold: it was particularly low-powered even for french cars of the time, the original model barely reached 40 mph (out of a 9 hp engine), and the later fastest models topped out around 70.
The 2CV had literally been designed to cross freshly ploughed fields and drive on unpaved roads, it just was not suitable for the interstate-expanding American market.
I had one of the faster models but even those could not reliably overtake a truck, chances are that when you tried to come out ahead of the lee of the truck you'd be blown back. More than once I had to sheepishly fall back all 60 feet to go back behind and let others pass.
