These vehicles include fire trucks, hook and ladder trucks, foam or water transport trucks, police SWAT team vehicles, ambulances, or other vehicles that are used in response to emergencies.

(3)(i) A driver, employed by an eligible unit of local government, operating a commercial motor vehicle within the boundaries of that unit for the purpose of removing snow or ice from a roadway by plowing, sanding, or salting, if

(A) The properly licensed employee who ordinarily operates a commercial motor vehicle for these purposes is unable to operate the vehicle; or

(B) The employing governmental entity determines that a snow or ice emergency exists that requires additional assistance.

(ii) This exemption shall not preempt State laws and regulations concerning the safe operation of commercial motor vehicles.

(e) Restricted commercial drivers license (CDL) for certain drivers in the State of Alaska.

(ii) Custom harvesters;

(iii) Farm retail outlets and suppliers;

(iv) Livestock feeders.

(2) A restricted CDL issued pursuant to this paragraph shall meet all the requirements of this part, except subpart H of this part. A restricted CDL issued pursuant to this paragraph shall be accorded the same reciprocity as a CDL meeting all of the requirements of this part. The restrictions imposed upon the issuance of this restricted CDL shall not limit a person’s use of the CDL in a non-CMV during either validated or non-validated periods, nor shall the CDL affect a State’s power to administer its driver licensing program for operators of vehicles other than CMVs.

(3) A State issuing a CDL under the terms of this paragraph must restrict issuance as follows:

(i) Applicants must have a good driving record as defined in this paragraph. Drivers who have not held any motor vehicle operator’s license for at least one year shall not be eligible for this CDL. Drivers who have between one and two years of driving experience must demonstrate a good driving record for their entire driving history. Drivers with more than two years of driving experience must have a good driving record for the two most recent years. For the purposes of this paragraph, the term good driving record means that an applicant:

(B) Has not had any license suspended, revoked, or canceled;

(C) Has not had any conviction for any type of motor vehicle for the disqualifying offenses contained in § 383.51(b);

(D) Has not had any conviction for any type of motor vehicle for serious traffic violations; and

(E) Has not had any conviction for a violation of State or local law relating to motor vehicle traffic control (other than a parking violation) arising in connection with any traffic accident, and has no record of an accident in which he/she was at fault.

(ii) Restricted CDLs shall have the same renewal cycle as unrestricted CDLs but shall be limited to the seasonal period or periods as defined by the State of licensure, provided that the total number of days in any calendar year for which the restricted CDL is valid does not exceed 210. If a State elects to provide for more than one seasonal period, the restricted CDL is valid for commercial motor vehicle operation only during the currently approved season, and must be revalidated for each successive season. Only one seasonal period of validity may appear on the license document at a time. The good driving record must be confirmed prior to any renewal or revalidation.

(iii) Restricted CDL holders are limited to operating Group B and C vehicles, as described in subpart F of this part.

(iv) Restricted CDLs shall not be issued with any endorsements on the license document. Only the limited tank vehicle and hazardous materials endorsement privileges that the restricted CDL automatically confers and are described in paragraph (f)(3)(v) of this section are permitted.

(v) Restricted CDL holders may not drive vehicles carrying any placardable quantities of hazardous materials, except for diesel fuel in quantities of 3,785 liters (1,000 gallons) or less; liquid fertilizers (i.e., plant nutrients) in vehicles or implements of husbandry in total quantities of 11,355 liters (3,000 gallons) or less; and solid fertilizers (i.e., solid plant nutrients) that are not transported with any organic substance.

(2) A State issuing a CDL under the terms of this paragraph must restrict issuance as follows:

(i) The GVWR of the vehicle to be operated must be less than 4,537 kilograms (10,001 pounds);

(ii) If a State believes, at its discretion, that the training required by § 172.704 of this title adequately prepares part-time drivers meeting the other requirements of this paragraph to deal with fireworks and the other potential dangers posed by fireworks transportation and use, the State may waive the hazardous materials knowledge tests of subpart H of this part. The State may impose any requirements it believes is necessary to ensure itself that a driver is properly trained pursuant to § 172.704 of this title.

(iii) A restricted CDL document issued pursuant to this paragraph shall have a statement clearly imprinted on the face of the document that is substantially similar as follows: “For use as a CDL only during the period from June 30 through July 6 for purposes of transporting less than 227 kilograms (500 pounds) of fireworks classified as DOT Class 1.3G explosives in a vehicle with a GVWR of less than 4,537 kilograms (10,001 pounds).

(3) A restricted CDL issued pursuant to this paragraph shall meet all the requirements of this part, except those specifically identified. A restricted CDL issued pursuant to this paragraph shall be accorded the same reciprocity as a CDL meeting all of the requirements of this part. The restrictions imposed upon the issuance of this restricted CDL shall not limit a person’s use of the CDL in a non-CMV during either validated or non-validated periods, nor shall the CDL affect a State’s power to administer its driver licensing program for operators of vehicles other than CMVs.

(4) Restricted CDLs shall have the same renewal cycle as unrestricted CDLs, but shall be limited to the seasonal period of June 30 through July 6 of each year or a lesser period as defined by the State of licensure.

(5) Persons who operate commercial motor vehicles during the period from July 7 through June 29 for purposes of transporting less than 227 kilograms (500 pounds) of fireworks classified as DOT Class 1.3G explosives in a vehicle with a GVWR of less than 4,537 kilograms (10,001 pounds) and who also operate such vehicles for the same purposes during the period June 30 through July 6 shall not be issued a restricted CDL pursuant to this paragraph.

(h) Exception for drivers of “covered farm vehicles.” The rules in this part do not apply to a driver of a “covered farm vehicle,” as defined in § 390.5 of this chapter.

(i) Hazardous materials endorsement exemption for certain drivers transporting diesel. A State may waive the requirement for a holder of a Class A commercial driver’s license to obtain a hazardous materials endorsement under this part, if the license holder is:

(1) Acting within the scope of the license holder’s employment, and within the State of domicile (or another State with a hazardous materials endorsement exemption) as an employee of a custom harvester operation, agrichemical business, farm retail outlet and supplier, or livestock feeder; and

(2) Operating a service vehicle that is:

(i) Transporting diesel in a quantity of 3,785 liters (1,000 gallons) or less; and
