The Silver Peak Risk Index (SPRI)

A clear, outcome-based measure of your fleet’s true safety performance.

The Silver Peak Risk Index (SPRI) is a proprietary 100-point safety score developed by Silver Peak Compliance. Using 24 months of FMCSA-reported data, SPRI gives carriers a straightforward, accurate view of how their safety performance compares to established safety expectations.

Unlike systems built on volatile percentile rankings or inconsistent enforcement activity, SPRI focuses only on real safety outcomes. It measures what actually happens during inspections and on the road. 

This produces a score that is stable, predictable, and easy for carriers to interpret.

SPRI measures results, not assumptions. Every part of the score is based on documented safety outcomes, such as:

• Trucks or drivers being placed Out-of-Service
• Crashes occurring relative to mileage
• Equipment violations found during inspections
• Whether crashes involve injuries or fatalities

These are real events recorded by FMCSA. They are not opinions, estimates, or percentiles that shift based on inspection patterns. When a fleet improves, SPRI reflects that improvement directly. When risk increases, the score shows it.

SPRI evaluates six outcome-based safety factors. Each factor is compared to a static SPRI Standard, ensuring your score only changes when your performance changes, not because national averages moved.

The SPRI Standards are:

• Driver Out-of-Service Rate: Benchmarked to 6.67%
• Vehicle Out-of-Service Rate: Benchmarked to 22.26%
• Maintenance Violation Load: Average number of equipment violations per vehicle inspection
• Crash Rate (per million miles): Benchmarked to 1.5
• Fatal Crash Rate (per million miles): Benchmarked to 0.0176
• Injury Crash Rate (per million miles): Benchmarked to 0.35

Scores stay low when a carrier performs at or better than expected safety levels. Scores increase when safety performance exceeds risk thresholds.

• Lower score = safer operations
• Higher score = greater likelihood of FMCSA attention

This simple structure makes the index intuitive for carriers, insurance brokers, and safety managers.

BASIC percentiles can rise or fall due to external factors unrelated to safety, such as:

• Where your fleet operates
• How often you are inspected
• Regional enforcement variations
• Small swings in violation activity

This makes performance difficult to interpret. SPRI avoids this issue by using outcome-based metrics and static benchmarks. 

Your score only changes when your performance changes.

SPRI is included in every Safety Profile we produce. It simplifies complex FMCSA data into a clear, meaningful score so carriers can instantly understand where their risk is coming from.

We use SPRI to:

• Identify the safety factors driving risk
• Explain why those factors matter
• Recommend corrective actions
• Track improvement over time

SPRI isn’t just a score. It is the tool that makes federal safety data clear and actionable.
