Motorcycle Inspection
PURPOSE: This rule lists the specific inspection standards and
procedures for the inspection of motorcycles and motor tricycles.
These standards are necessary because of difference in vehicle
design and different tolerances involved.
HIGHWAY PATROL
(1) This section of the inspection manual contains procedures
which shall be followed when inspecting motorcycles and
motor tricycles.
(A) Brakes.
1. Brake efficiency shall be determined by operating the
vehicle on the inspection stationโs premises. This test may be
conducted either by the inspector/mechanic or by the vehicle
owner with the inspector/mechanic observing. Brakes must be
installed and in operating condition on each wheel if originally
equipped by the manufacturer.
2. Apply each brake control separately while vehicle is
in motion, apply moderate force to brakes for one (1) minute;
inspect wheel and master cylinder for leakage if equipped
with hydraulic brakes; inspect master cylinder for fluid level if
equipped with hydraulic brakes; inspect brake hoses or tubing
for broken, flattened or restricted sections and improper
support; inspect brake rods or cables for wear and proper
adjustment.
3. Reject vehicle if:
A. Any brake fails to indicate braking action;
B. Not equipped with required brakes;
C. Brake pedal height cannot be maintained for one (1)
minute, leakage is indicated;
D. Less than one-third (1/3) of the pedal reserve remains;
E. Pedal fails to return to the fully released position after
application;
F. Wheel or master cylinder leaks;
G. Fluid level in the master cylinder is below the level
recommended by the manufacturer;
H. Brake hose is broken or restricted and if hose is not
supported to prevent damage by rubbing with the frame or
other components;
I. Brake cable is badly frayed or if rod, clevises and
couplings are badly worn;
J. Any pins, springs or other mechanical parts are
missing, defective or badly worn; or
K. Brake rods or cables are not adjusted properly.
(B) Lighting Equipment.
1. Headlights. Every vehicle shall be equipped with at
least one (1) and not more than two (2) headlights. A headlight
shall exhibit light substantially white in color. A motorcycle
equipped with a sidecar or other attachment shall be equipped
with a light on the outside limit of the attachment capable of
displaying a white light to the front.
2. Taillights and reflectors. Every vehicle shall be equipped
with at least one (1) red taillight and at least one (1) red reflector.
Any vehicle with two (2) rear wheels shall be equipped with at
least two (2) red taillights and two (2) red reflectors. A reflector
may be part of the taillight or it may be separate. The taillight
shall be mounted at a height of not more than seventy-two
inches (72") nor less than fifteen inches (15") above the ground.
The reflector shall be mounted at a height not greater than
sixty inches (60") nor less than fifteen inches (15") above the
ground.
3. Signalling devices. If the vehicle is equipped with turn
signals and a stoplight, all must operate.
4. Inspect lighting equipment, reflectors and signalling
devices.
5. Reject vehicle if:
A. Not equipped with required headlight, taillights or
reflectors;
B. A headlight has reflector deterioration;
C. A lens is badly broken, missing, incorrectly installed
or repaired with tape;
D. Any light fails to function properly;
E. Any light or reflector is not securely mounted or
shows a color contrary to law;
F. Beam indicator or dimmer switch, if so equipped, fails
to operate properly; or
G. A taillight or reflector is not mounted in the prescribed
area.
(C) Steering Mechanisms.
1. Inspect to determine the condition of the frame, fork,
steering head bearing, handlebars and front and rear wheel
tracking. Check wheel bearings by elevating and rotating each
wheel. Inspect condition of grease retainers. If equipped by the
manufacturer, actuate front and rear shock absorbers.
2. Reject vehicle if:
A. Frame or fork is bent, broken or wheels are out of line
where it affects the steering and control;
B. Loose, defective or worn components in steering head
bearing;
C. Handlebars are loose, bent, broken or damaged where
it affects proper steering;
D. Any portion of the handlebars extend over fifteen
inches (15") in height above the normal riding position unless
originally equipped by the motorcycle manufacturer;
E. Wheel bearings have excessive horizontal movement
or, when rotated, unusual noise exists;
F. Grease retainer is defective; or
G. A shock absorber is disconnected, broken, bent or
missing.
(D) Tires and Wheels.
1. Inspect tires for tread wear, cord exposure, knots, cuts,
tread separation and condition of wheel and rims.
2. Reject vehicle if:
A. Any tire is worn at any one (1) point where there is no
tread design across half of the tire tread;
B. Tire has an exposed cord, bulge or knot;
C. A tire is marked reject, rejected, not for highway
use, farm use only, for nonhighway use, for race track use
only or marked with similar terms, or if determined beyond a
reasonable doubt that these markings have been removed. This
does not include tires labeled with the word blemish;
D. A wheel has any loose, missing or defective bolts,
nuts, lugs or spokes;
E. A wheel is damaged or defective; or
F. Any wheel wobbles more than three-sixteenths inch
(3/16").
(E) Horn.
1. Every vehicle shall be equipped with a horn, in good
working order and capable of emitting a sound adequate in
quantity and volume to give warning of the approach of the
vehicle to other users of the highway.
2. Determine if horn is securely fastened, audible and if
electrical connections are properly grounded.
3. Reject vehicle if:
A. Vehicle is not equipped with a horn;
B. Horn is not audible under normal conditions;
C. Horn is not firmly mounted; or
D. Horn is actuated by grounding two (2) naked wires or
a similar method. Defective wiring or electrical connections.
(F) Muffler and Exhaust System.
1. The motor shall be fitted with a properly attached
muffler.
2. Inspect condition of muffler and exhaust pipe. If the
vehicle is equipped with a dual exhaust system, both must be
examined.
3. Inspect supporting hardware, attachments and brackets.
Exhaust system must be securely attached at the cylinder head,
manifold and to the frame at or near the place where the
exhaust pipe attaches to the muffler.
4. Reject vehicle if:
A. Not equipped with a muffler;
B. Muffler or exhaust pipe has holes, loose joints or
leaking seams. Only patches made with an arc or acetylene
weld will be permitted;
C. Exhaust system components are not securely fastened;
D. Tailpipe is not securely fastened to the muffler; or
E. A modified high rise tailpipe is positioned so it could
easily burn the operator.

vision of the road ahead.
2. Reject vehicle:
A. If the windshield is cracked, scarred or defaced to the
extent that it does not provide a clear vision.

filler cap.
2. Reject vehicle if:
A. There is fuel leakage at any location;
B. Fuel tank is not securely attached; or
C. Filler cap is missing or does not fit.
