PURPOSE: This rule lists the minimum hours of operation for

inspect vehicles. This rule is necessary to ensure that stations will
be open and available for inspection purposes.

safety inspection station shall be at least eight (8) continuous
hours per day, five (5) days per week, except for businesses
licensed as part-time motor vehicle safety inspection stations.
(2) Inspection station operators, inspector/mechanics, or both,
are obligated to conduct inspections and reinspections of
vehicles during normal business hours. A vehicle shall be
inspected within a two- (2-) hour period after being presented
unless other vehicles are being inspected. A reinspection must
begin within one (1) hour when a vehicle is presented during
the twenty (20) consecutive-day period excluding Saturdays,
Sundays, and state holidays allowed by law for reinspections.
(3) The superintendent of the Missouri State Highway Patrol
may, at his/her discretion, authorize the licensing of part-time
motor vehicle safety inspection stations for businesses that do
not operate within a traditional forty- (40-) hour work week.
A business that is open forty (40) or more hours per week is
not eligible for licensing as a part-time motor vehicle safety
inspection station.
(A) Part-time motor vehicle safety inspection stations must
be open to the public during all business hours established at
the time of application.
(B) The Missouri State Highway Patrol shall consider only
business hours between the hours of 6 a.m. and 10 p.m. for
the calculation of normal business hours of part-time motor
vehicle safety inspection stations.
(C) Normal business hours for part-time motor vehicle safety
inspection stations will be, at a minimum, twenty (20) hours
per calendar week, and must be posted on the Notice to
Vehicle Owner poster.
(D) Regardless of normal business hours posted on the
Notice to Vehicle Owner poster, part-time motor vehicle safety
inspection stations shall be required to perform motor vehicle
safety inspections at any time the business is open between the
hours of 6 a.m. and 10 p.m.
(E) A business licensed as a part-time motor vehicle safety
inspection station is prohibited from operating a station in a
facility that is used by another business licensed as a motor
vehicle inspection station.
(4) The superintendent of the Missouri State Highway Patrol
may, at his/her discretion, cease the licensing of part-time
motor vehicle safety inspection stations. Should the licensing
of part-time motor vehicle safety inspection stations cease,
all part-time stations shall be allowed to remain as part-time
inspection stations until expiration of the current licensing
period, and no renewal of the license shall be completed.
