I have "HEMOTOX" as my viper license. I was searching the web for something related to viper venom when I first bought the 2001 GTS. As you can expect, "venom, hssss, snake, etc." all are taken in the California DMV. So I found this website by an Indian Physician who described the condition "Ophiotoxemia" which is the medical term for snake bite poisoning. So "OPHOTOX" and "OPHIOTX" were available but no one would know what they meant. In reading the article, the Indian Physician describes basically two types of poisoning, hemotoxin and neurotoxin based processes. Bottom line is the viper class of poisonious snakes are hemotoxic, meaning that their poison breaks down blood products resulting in vascular collapse of the victim, while cobra class of snakes kill by neurotoxic venom effecting the central nervous system eventually causing paralysis and death. So I punched in "HEMOTOX" at the California DMV custom web site amd Bingo, they took it and didn't ask any long explanation. My license plate made Viper Magazine! I just ordered "LEMAN66", for my 06 Tungsten GT. :cheers
PS, since the FORD GT40 was a cobra based engine and management team with Carroll Shelby and Shelby American placing 1-2 in the 1966 Le Mans Race (Holman-Moody sponsored car #5 GT40 was 3rd), I would think an appropriate custom license plate for any one interested would be "NEROTOX" or "NUROTOX" for the cobra class of poisonous snakes, n'est pas?
