1. Which type of automotive glass is most commonly used for
windshields?
A. Tempered glass
B. Acrylic plastic
C. Laminated glass
D. Polycarbonate
Windshields are typically laminated glass: two glass layers bonded to
a plastic interlayer, usually PVB. This construction keeps the glass
largely intact after impact and reduces the risk of occupants being
ejected through the opening. Tempered glass is commonly used in side
and rear windows, while acrylic and polycarbonate are plastics rather
than standard windshield glazing materials.
, 2. Which type of automotive glass is most commonly used for side
and rear windows?
A. Laminated glass
B. Tempered glass
C. Wired glass
D. Insulated glass
Tempered glass is heat-treated so that, when broken, it fractures into
small, relatively blunt pieces rather than large sharp shards. This
makes it suitable for many side and rear openings. Some modern
vehicles use laminated side glass for acoustic or security benefits, but
tempered glass remains the traditional and most common choice.
3. The plastic interlayer in a laminated windshield is primarily
intended to:
A. Improve fuel economy
B. Hold broken glass together after impact
C. Increase electrical conductivity
D. Prevent ultraviolet fading of upholstery
The PVB or similar interlayer bonds the two glass plies together. When
the windshield cracks, the interlayer helps retain fragments and
maintain a barrier. Laminated glass may also filter some UV radiation,
,but its principal safety function is holding the glass together after
impact.
4. What is the proper first step before removing a damaged
windshield?
A. Cut the urethane immediately
B. Remove all interior trim
C. Inspect the vehicle and identify the glass, molding, sensors,
and attachment method
D. Apply new primer
A pre-installation inspection identifies the correct replacement part,
molding or clip requirements, embedded technology such as rain/light
sensors or cameras, corrosion, and whether the glass is bonded or
mechanically fastened. Removing trim or cutting adhesive before this
assessment can cause unnecessary damage or leave the installer
without needed parts.
5. Before installing a bonded windshield, the pinchweld should be
inspected primarily for:
A. Paint overspray only
B. Rust, corrosion, and structural damage
C. Tire pressure
D. Wiper-blade wear
, The pinchweld is the flanged body opening to which the windshield
bonds. Corrosion, bent metal, prior repair damage, or structural
compromise can prevent a secure bond and may require repair before
glass installation. A weak pinchweld can compromise windshield
retention in a collision.
6. Which tool is most commonly used to cut through cured urethane
adhesive during windshield removal?
A. Heat gun
B. Cold knife or electric vibration knife
C. Rivet gun
D. Torque wrench
Cold knives and powered vibration knives are designed to sever cured
urethane around the glass perimeter. Heat guns may soften adhesive
in some situations, but they are not the standard primary cutting tool
for a bonded windshield. Rivet guns and torque wrenches are
unrelated to adhesive removal.
7. When using a cold knife, the installer should primarily protect:
A. The vehicle’s exhaust system
B. The body, trim, glass, and the installer’s hands
C. The transmission pan
D. The fuel tank
