Hazmat and placards.
The hazmat endorsement is good to have and most of the big outfits require one anyway. We regularly haul unreportable amounts of hazmat in our grocery and non grocery loads without placards. Bic lighters,propane camping cylinders and paint thinner are all items mixed on our loads daily and considered non reportable up to certain weights. The same trailers always have some sort of foodstuffs candy,gum,nuts and on straight grocery trailers they will sometimes drop a board of mixed hardlines the above mentioned types of hazmat,televisions and the anything else that might have been late in the pick cycle.
