Endorsements

For operation of a commercial motor vehicle, (Classes A, B or C), a driver may also obtain one or more endorsements. The Class D license can also have a school bus endorsement if the vehicle is designed to carry less than 16 persons including the driver. Each endorsement requires a special knowledge test when originally issued.

The school bus "S" endorsement and the hazardous materials "H" endorsement require a knowledge test when originally issued and upon every renewal. The school bus "S" endorsement also requires a driving skills test when originally issued and upon every renewal. The passenger "P" endorsement requires a driving skills test when originally issued. Wisconsin endorsements are:
