The cost of a permit test for class A and B commercial driver's licences varies by state. Examples include $27 in Ohio, $10 for the written test and $40 for the driving test in New York, and $15 for the permit in South Carolina, according to each state's DMV website.
In addition to various fee structures in different states, each state has different requirements that must be met and forms that must submitted before a permit is issued. For example, New York requires a 10-year driving history, including record of licenses held in other states, according to the New York Department of Motor Vehicles. Ohio requires applicants to bring their Social Security card, reports the Ohio Bureau of Motor Vehicles.
