1. A technician is preparing a damaged vehicle for structural repair.
Which initial step is most important before any disassembly begins?
A. Begin welding cracked areas immediately
B. Disconnect the battery and disable restraint systems
C. Apply body filler to all visible dents
D. Start sanding damaged panels
B
Disconnecting the battery and disabling restraint systems is essential
because it prevents accidental airbag deployment and electrical hazards
during disassembly, ensuring technician safety throughout the repair
process.
2. Which measurement system is most commonly used to restore a
vehicle’s frame to factory specifications?
A. Ohm meter system
B. Structural dimension chart system
, C. Hydraulic pressure chart
D. Paint mixing ratio guide
B
Structural dimension charts provide precise factory measurements that
allow technicians to restore frame alignment accurately and ensure the
vehicle meets original safety standards.
3. What is the primary purpose of a weld-through primer in collision
repair?
A. To increase paint gloss
B. To prevent corrosion in overlapped metal joints
C. To strengthen plastic bumpers
D. To reduce sanding time on fillers
B
Weld-through primer is applied to metal surfaces that will be welded
together to prevent rust formation in areas that will be inaccessible after
joining.
4. When performing a sectioning repair on a unibody vehicle, where
should the cut typically be made?
A. At the weakest rusted point
B. At manufacturer-approved sectioning locations
C. Anywhere on the panel edge
D. Through the center of structural reinforcements
B
Manufacturers specify approved sectioning points to maintain structural
integrity and ensure the repaired vehicle performs safely in a collision.
5. Which type of damage is most likely to require frame straightening
equipment?
, A. Light surface scratches
B. Deep paint fading
C. Structural misalignment after collision
D. Minor interior trim damage
C
Structural misalignment affects the vehicle’s geometry and requires
specialized frame straightening equipment to restore proper alignment
and safety.
6. What is the primary function of MIG welding in auto body repair?
A. To bond plastic panels
B. To join metal components using a continuous wire feed
C. To polish aluminum surfaces
D. To measure panel gaps
B
MIG welding uses a continuous wire feed and shielding gas to create
strong, clean welds commonly used in collision repair for steel components.
7. Which safety equipment is essential when grinding metal surfaces?
A. Leather gloves only
B. Safety goggles and face shield
C. Sunscreen and hat
D. Earplugs only
B
Safety goggles and a face shield protect against flying metal particles and
sparks generated during grinding operations.
8. What is the purpose of a vehicle measuring system in collision repair?
A. To improve paint adhesion
B. To detect engine faults
, C. To verify structural alignment
D. To balance wheel alignment
C
Vehicle measuring systems ensure that structural components are aligned
correctly according to manufacturer specifications after collision damage.
9. Which material is most commonly used as body filler in collision
repair?
A. Epoxy resin only
B. Polyester-based filler
C. Aluminum paste
D. Silicone grease
B
Polyester-based body filler is widely used due to its ease of shaping,
sanding, and adhesion to properly prepared metal surfaces.
10. What is the primary purpose of corrosion protection after panel
replacement?
A. To increase vehicle weight
B. To improve engine cooling
C. To prevent rust formation on exposed metal
D. To enhance tire grip
C
Corrosion protection prevents oxidation and rust on repaired or replaced
metal surfaces, extending vehicle life and safety.
11. Which tool is used to remove spot welds during panel
replacement?
A. Air compressor
B. Spot weld cutter
