,Q1. A commercial motor vehicle (CMV) is found with a cracked steering wheel rim
that is not loose. Per FMCSA standards, this is a violation. What is the correct
classification and out-of-service (OOS) criterion?
A. Non-OOS violation; repair within 15 days.
B. OOS violation if the crack is longer than 2 inches.
C. OOS violation if any crack is present in the steering wheel rim.
D. Non-OOS violation; no immediate repair required.
Correct Answer: C. OOS violation if any crack is present in the steering wheel rim.
Rationale: FMCSA regulation 393.209(d) states a steering wheel with any crack is an
OOS violation because the wheel could fail during operation. A cracked rim, even if not
loose, compromises structural integrity, making it an immediate hazard. Options A, B, and
D incorrectly minimize the severity or add conditions not in the regulation.
Why Wrong:
A - Incorrect: A cracked steering wheel rim is an OOS violation, not a minor repair.
B - Incorrect: FMCSA does not specify a crack length; any crack is OOS.
D - Incorrect: It requires immediate repair, not optional deferral.
Reference: FMCSA 49 CFR 393.209(d)
Q2. During a Level 1 inspection, you observe a hydraulic brake hose with chafing that
has worn through the outer cover but does not expose the inner reinforcement. Per
FMCSA standards, what is the correct classification?
A. OOS violation because any chafing is unacceptable.
B. Non-OOS violation; must be repaired within 24 hours.
C. OOS violation if the chafing is longer than 3 inches.
D. Non-OOS violation; no immediate repair required.
Correct Answer: D. Non-OOS violation; no immediate repair required.
Rationale: FMCSA 393.45(b)(2) requires that chafing must be worn through the outer
cover AND expose the reinforcement layer to be a violation. Since the reinforcement is not
exposed, the hose is compliant. Thus, it is not a violation and no repair is required.
Options A, B, C, and E misstate the criteria.
Why Wrong:
A - Incorrect: Chafing alone is not a violation unless it exposes reinforcement.
B - Incorrect: No repair is required because it is not a violation.
C - Incorrect: No length threshold is specified for chafing; exposure is key.
Reference: FMCSA 49 CFR 393.45(b)(2)
Q3. A truck driver presents a medical examiner's certificate that is 3 months expired.
The driver is operating under a valid CDL and has no other violations. What is the
correct enforcement action?
Page 3
, A. Place driver OOS and issue a citation for operating without a valid medical
certificate.
B. Allow driver to continue if they have a valid CDL.
C. Issue a citation but allow driver to continue to next destination.
D. Confiscate the CDL and impound the vehicle.
Correct Answer: A. Place driver OOS and issue a citation for operating without a
valid medical certificate.
Rationale: Per FMCSA 391.45, a driver must have a valid medical certificate. An expired
certificate is a violation, and the driver is considered physically unqualified. Therefore, the
driver must be placed OOS and cited. The CDL does not override the medical requirement.
Options B, C, D, and E are incorrect because they do not address the OOS requirement.
Why Wrong:
B - Incorrect: A valid CDL does not substitute for a valid medical certificate.
C - Incorrect: The driver must be placed OOS immediately.
D - Incorrect: Confiscation and impoundment are not standard for this violation.
Reference: FMCSA 49 CFR 391.45
Q4. During a Level 2 inspection, you find that a CMV's brake lights are not
functioning. The vehicle is not placed OOS for this defect. What is the correct
classification and required action?
A. Non-OOS violation; driver must repair within 24 hours.
B. OOS violation; vehicle must be repaired before continuing.
C. Non-OOS violation; driver may continue but must repair within 15 days.
D. OOS violation if the vehicle is operated at night.
Correct Answer: A. Non-OOS violation; driver must repair within 24 hours.
Rationale: Inoperative brake lights are a non-OOS violation but must be repaired within
24 hours per FMCSA regulations. This is because they pose a safety risk but do not
require immediate OOS action. Options B and D are incorrect because it is not an OOS
violation. Option C is incorrect because the repair timeframe is 24 hours, not 15 days.
Option E is incorrect because repair is required regardless of driver awareness.
Why Wrong:
B - Incorrect: Brake lights are not an OOS violation.
C - Incorrect: The repair must be done within 24 hours, not 15 days.
D - Incorrect: Night operation does not change the classification.
Reference: FMCSA 49 CFR 393.9(a), 396.3
Q5. A driver's Record of Duty Status (RODS) shows a violation of the 14-hour rule.
The driver claims they were delayed by traffic and could not find a safe parking spot.
What is the correct enforcement action?
