A waiver is temporary regulatory relief from one or more of the FMCSRs given to a person subject to the regulations, or a person who intends to engage in an activity that would be subject to the regulations. A waiver provides the person with relief from the regulation for up to three months. 49 CFR 391.64 provides waivers to CMV drivers who were in the initial vision and insulin programs in the early 1990's.

An exemption is a temporary regulatory relief from one of more of the FMCSRs given to a person or class of persons subject to the regulations, or who intend to engage in an activity that would make them subject to the regulation. An exemption provides the person or class of persons with relief from the regulations for up to two years, but may be renewed.
