What is Are Overweight Tickets Used in the SMS Calculations?
One of the most frequent questions fleet managers and drivers ask is: are overweight tickets used in the sms calculations? The Safety Measurement System (SMS) is the FMCSA’s method for identifying high-risk motor carriers. It organizes inspection data into several Behavioral Analysis and Safety Improvement Categories (BASICs).
While size and weight violations are recorded during roadside inspections and appear on a carrier’s profile, they are currently assigned a severity weight of zero in the public BASIC scores. This means that while they show up on your record, they do not directly inflate your Unsafe Driving or Vehicle Maintenance percentiles. However, they are vital to track because they often trigger a full Level I or Level II inspection, which may reveal other violations that do carry heavy point values.
Understanding are overweight tickets used in the sms calculations helps carriers focus their safety resources. Misconceptions often lead people to believe an overweight ticket will immediately trigger an intervention; in reality, it is the secondary violations discovered during the stop that usually cause the damage.
Are Overweight Tickets Used in the SMS Calculations? Formula and Mathematical Explanation
The calculation of a BASIC measure follows a specific weighted average formula. To understand how are overweight tickets used in the sms calculations, we must look at the variables involved in the point calculation.
The standard formula for an SMS BASIC measure is:
Measure = Total Weighted Violations / (Safety Event Group or Normalization Factor)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Violation Severity | The assigned weight of a specific violation (e.g., speeding). | Points | 1 – 10 |
| Time Weight | Multiplier based on how recent the violation is. | Multiplier | 1x, 2x, or 3x |
| Power Units (PU) | Average number of trucks in the fleet over 18 months. | Count | 1 – 50,000+ |
| Utilization Factor | Adjustment based on VMT (Vehicle Miles Traveled). | Ratio | 0.9 – 1.2 |
| Overweight Impact | Points contributed by size/weight violations. | Points | 0 (Current SMS) |

Practical Examples (Real-World Use Cases)
Example 1: The Independent Owner-Operator
An owner-operator (1 Power Unit) receives an overweight ticket (80,500 lbs on a 80,000 lb limit) and a speeding ticket (11-14 mph over) within the same month. When considering are overweight tickets used in the sms calculations, we calculate: Speeding (7 points × 3 time weight) = 21 points. The overweight ticket = 0 points. The total measure is 21 / 1 = 21.0. If the overweight ticket had a weight of 5, the score would have jumped to 36.0, illustrating why the current zero-weighting is beneficial for carriers.
Example 2: Regional Mid-Sized Fleet
A fleet with 20 Power Units has accumulated 5 logbook violations (average severity 5) over 8 months. They also received 12 overweight tickets. When asking are overweight tickets used in the sms calculations, the fleet manager realizes the 12 tickets contribute 0 points. The calculation remains: (5 violations × 5 severity × 2 time weight) / 20 = 2.5 Measure. The 12 overweight tickets do not change this math.
How to Use This Are Overweight Tickets Used in the SMS Calculations? Calculator
Following these steps will help you estimate your potential impact:
- Step 1: Enter the count of standard moving violations (like speeding or reckless driving).
- Step 2: Input the Average Severity Weight. You can find these values in the FMCSA SMS Methodology document.
- Step 3: Select the Time Weight. Choose “Recent” if the violations occurred in the last 6 months.
- Step 4: Enter your “Overweight Tickets” count. You will notice the calculator adds 0 points for these, reflecting current FMCSA policy.
- Step 5: Input your total Power Units to see how the “Measure” is normalized across your fleet size.
- Step 6: Review the chart to see the visual discrepancy between moving violations and overweight impact.
Key Factors That Affect Are Overweight Tickets Used in the SMS Calculations? Results
When analyzing your safety data, several factors influence the final results beyond just the violation count:
- Violation Grouping: Even though are overweight tickets used in the sms calculations yields zero, if that ticket is categorized under “Unsafe Driving” (rare), it could change. Currently, they sit in the “Size and Weight” category.
- Inspection Intensity: Overweight vehicles are frequently pulled into scales, increasing the probability of a “Clean Inspection.” Clean inspections actually help your score by increasing the denominator in certain calculations.
- Time Decay: Points lose half their value after 12 months and disappear after 24. Even a high-severity ticket becomes less impactful over time.
- Fleet Utilization: If your VMT is high, the FMCSA applies a utilization factor that can lower your measure, making your violations count for “less” relative to your exposure.
- Peer Grouping: Your percentile is not just your measure; it is how your measure compares to others with similar numbers of inspections.
- Data Integrity (DataQs): If you received an overweight ticket that was dismissed in court, you must use the DataQs system to remove it, as even 0-point violations can look bad to shippers or insurers.
