CEVO 4 Test Exam 2025 — Full 150-Question
Practice Exam with correct answers and
rationale graded A+
Section 1: Vehicle Inspection and Maintenance (Questions 1–15)
1. When inspecting your ambulance:
A. Check only the exterior lights
B. Check only the tires and brakes
C. All of the above
D. Only check items noted on the previous shift's report
Answer: C. All of the above
Rationale: A complete ambulance inspection includes exterior, interior, mechanical, and emergency
equipment checks. Partial inspections create safety risks. -1-5
2. Check that the ambulance's tires are properly inflated by:
A. Kicking each tire
B. Using an appropriate gauge
C. Squeezing the sidewall
D. Visual inspection only
Answer: B. Using an appropriate gauge
Rationale: Visual inspection and kicking tires cannot accurately determine proper inflation pressure.
A calibrated tire gauge is the only reliable method. -1-10
3. Properly adjusted mirrors will:
A. Eliminate all blind spots
B. Reduce your blind spots
C. Make backing unnecessary
D. Allow you to see 360 degrees
Answer: B. Reduce your blind spots
Rationale: No mirror configuration eliminates all blind spots. Proper adjustment reduces their size
but does not remove them entirely. -1-5
4. The front tires of the ambulance should have a minimum tread depth of:
A. 2/32 of an inch
B. 4/32 of an inch
C. 6/32 of an inch
D. 8/32 of an inch
Answer: B. 4/32 of an inch
Rationale: Front tires require greater tread depth for steering control. 4/32" is the minimum
standard for front tires on emergency vehicles. -1-9
5. As you approach the ambulance to perform an inspection, do all of the following except:
A. Walk around the vehicle
,B. Check for fluid leaks
C. Kick each tire to check for proper inflation
D. Look for body damage
Answer: C. Kick each tire to check for proper inflation
Rationale: Kicking tires is ineffective and potentially damaging. A gauge must be used to verify tire
pressure. -1-2
6. A vehicle's stopping distance can be affected by:
A. Road conditions only
B. Driver reaction time only
C. Vehicle weight and speed only
D. All of the above
Answer: D. All of the above
Rationale: Stopping distance is influenced by road surface, reaction time, vehicle weight, speed,
brake condition, and tire traction. -2-8
7. Which of the following is not a component of your total stopping distance?
A. Perception distance
B. Reaction distance
C. Following distance
D. Braking distance
Answer: C. Following distance
Rationale: Total stopping distance = perception distance + reaction distance + braking distance.
Following distance is the space you maintain behind another vehicle, not a component of stopping
distance itself. -1-5
8. Total stopping distance is:
A. Easy to calculate precisely
B. Difficult to predict accurately
C. Always the same regardless of conditions
D. Measured in car lengths
Answer: B. Difficult to predict accurately
Rationale: Many variables (road surface, tire condition, load, reaction time) make precise prediction
impossible. Drivers must maintain a safety margin. -5-8
9. The average reaction time for all drivers is:
A. 1/4 of a second
B. 1/2 of a second
C. 3/4 of a second
D. 1 second
Answer: C. 3/4 of a second
Rationale: Average driver reaction time is approximately 0.75 seconds. Emergency vehicle operators
must account for this delay in stopping distance calculations. -5
10. Covering your brake will:
A. Increase your reaction time
B. Help reduce your reaction time
, C. Have no effect on reaction time
D. Damage the brake system
Answer: B. Help reduce your reaction time
Rationale: Keeping your foot over the brake pedal (without depressing it) reduces the time needed
to begin braking in an emergency. -2-5
11. When inspecting your ambulance, all of the following should be checked except:
A. Emergency lights and sirens
B. Fluid levels
C. Tire pressure
D. The patient's insurance information
Answer: D. The patient's insurance information
Rationale: Vehicle inspection focuses on mechanical and safety equipment, not administrative
paperwork. -1
12. Proper tire inflation is important because:
A. It affects fuel economy only
B. It affects handling and stopping distance
C. It only matters in wet conditions
D. It is only a comfort issue
Answer: B. It affects handling and stopping distance
Rationale: Under- or over-inflated tires reduce traction, increase stopping distance, and negatively
impact vehicle handling. -5
13. If you notice a mechanical issue during your inspection, you should:
A. Ignore it if the vehicle still starts
B. Report it and document it before operating
C. Fix it yourself without reporting
D. Wait until the end of your shift to report
Answer: B. Report it and document it before operating
Rationale: All mechanical issues must be documented and reported. Operating a vehicle with known
safety defects endangers everyone. -1
14. Windshield wipers should be inspected:
A. Only during rainy season
B. As part of every pre-shift inspection
C. Once a month
D. Only when they stop working
Answer: B. As part of every pre-shift inspection
Rationale: Wipers are critical for visibility in adverse weather. They should be checked every shift. -1
15. The ambulance's emergency lights and siren should be tested:
A. Once a week
B. At the beginning of every shift
C. Only before emergency calls
D. Once a month
