All HD diesels are limited to 5 mph in the most severe SCR driver inducement mode. The most severe driver inducement mode occurs after 20 hours after the DEF pump loses prime OR if the DEF pump loses prime and the operator cycles the keyswitch, so there is plenty of time to get more DEF. 5 mph is basically enough to get off the road and call a tow truck. All it requires for repair is to fill the DEF tank and the fault codes to be cleared. Basically, the EPA really really want the operators to keep DEF tanks from going empty.
