MTO Legal Regulations & Compliance 3 — Questions and Answers
Question 1: A motor carrier operating vehicles over 10,000 lbs GVWR in interstate commerce must register under which FMCSA program?
- Unified Carrier Registration (UCR) (Correct answer)
- Commercial Vehicle Safety Alliance (CVSA)
- Compliance, Safety, Accountability (CSA)
- Motor Carrier Identification Report (MCS-150)
Correct answer: Unified Carrier Registration (UCR)
The Unified Carrier Registration program requires interstate motor carriers to register and pay annual fees based on fleet size.
Question 2: Under 49 CFR Part 395, the 60/7 rule limits a driver to how many on-duty hours over 7 consecutive days?
- 55 hours
- 60 hours (Correct answer)
- 70 hours
- 80 hours
Correct answer: 60 hours
The 60/7 rule caps a driver at 60 hours on duty in any 7 consecutive days for carriers that do not operate every day of the week.
Question 3: Which type of CMV brake inspection violation most commonly results in an immediate out-of-service order?
- Slightly low brake fluid
- Brake adjustment exceeding allowable limits (Correct answer)
- Minor brake dust accumulation
- Slightly worn but within-limit brake pads
Correct answer: Brake adjustment exceeding allowable limits
Brakes adjusted beyond FMCSA out-of-service criteria are one of the top causes of immediate OOS orders during roadside inspections.
Question 4: What is the purpose of the FMCSA's Safety Measurement System (SMS)?
- To issue commercial driver's licenses
- To calculate insurance premiums for carriers
- To identify high-risk carriers for intervention using safety data (Correct answer)
- To set fuel efficiency standards for CMVs
Correct answer: To identify high-risk carriers for intervention using safety data
SMS uses inspection, crash, and violation data to prioritize motor carriers for safety interventions based on their risk scores.
Question 5: A driver who refuses to submit to a post-accident drug test required by DOT regulations is treated as:
- Suspended for 30 days pending review
- Having tested positive and is immediately disqualified from safety-sensitive functions (Correct answer)
- Given a second chance to test within 24 hours
- Issued a written warning for first offense
Correct answer: Having tested positive and is immediately disqualified from safety-sensitive functions
A refusal to test under 49 CFR Part 40 is treated the same as a positive test result, triggering immediate removal from safety-sensitive duties.
