Signs You Have Food Poisoning Cramps in your stomach and gut, diarrhea, and vomiting may start as early as 1 hour after eating tainted food and as late as 10 days or longer. It depends on what is causing the infection.
However, a farmer driving a commercial motor vehicle with double or triple trailers or designed to carry or actually carrying 16 or more passengers must have a CDL with proper endorsements.
If you take the road test in a truck without air brakes, you will have an air brake restriction. So, as long as your not hauling hazmat and is not a bus hauling 16 or more persons and your truck is registered for less than 26,001 lbs you do not need a cdl.
