Sec.  393.80  Rear-vision mirrors.



    (a) Every bus, truck, and truck tractor shall be equipped with two 

rear-vision mirrors, one at each side, firmly attached to the outside of 

the motor vehicle, and so located as to reflect to the driver a view of 

the highway to the rear, along both sides of the vehicle. All such 

regulated rear-vision mirrors and their replacements shall meet, as a 

minimum, the requirements of FMVSS No. 111 (49 CFR 571.111) in force at 

the time the vehicle was manufactured.

    (b) Exceptions. (1) Mirrors installed on a vehicle manufactured 

prior to January 1, 1981, may be continued in service, provided that if 

the mirrors are replaced they shall be replaced with mirrors meeting, as 

a minimum, the requirements of FMVSS No. 111 (49 CFR 571.111) in force 

at the time the vehicle was manufactured.

    (2) Only one outside mirror shall be required, which shall be on the 

driver's side, on trucks which are so constructed that the driver has a 

view to the rear by means of an interior mirror.

    (3) In driveway-towaway operations, the driven vehicle shall have at 

least one mirror furnishing a clear view to the rear.
