What Is Symbol 10 In Auto Insurance? 
Symbols are used to designate various types of auto coverage on a business auto policy . They range from 1-9 and 19 for business auto , 21-31 for garage keepers coverage , 41-50 and 59 for truckers , and 61-71 and 79 for motor carriers . For example , symbol 1 refers to `` Any Auto '' and is the broadest designation , allowing the coverage for any automobile an insured my find the need to drive . Symbol 10 is one of the ` custom ' symbols , meaning the use of the vehicle has a meaning that has been modified from one of the standard symbol designations for that class of vehicles . In these cases , the auto in question does not fit 100 % into one of the standard symbol designations , so the insured and the insurer agree to a custom definition of use .
