ELD telematics, CSA scores, safety bonus programs, and driver training credits can stack to a quarter off your annual premium — if you know how to claim them. This is the practical guide.
The biggest single discount available to commercial truck operators in 2026. Carriers reward drivers who share behavior data through approved Electronic Logging Devices.
Connect any FMCSA-approved ELD that integrates with Smart Haul. Discount applied at renewal based on a 6-month behavior score covering speeding, harsh braking, and HOS compliance.
Cover Whale runs an in-house telematics scoring engine. Best-in-class drivers can hit 22% credits stacked on the base rate; new policies get a starting credit during the first quarter.
Your CSA Safety Measurement System (SMS) profile is pulled by underwriters at every renewal. Two carriers will quote the same truck very differently based on your BASIC scores.
| BASIC category | Good profile | Bad profile | Premium impact |
|---|---|---|---|
| Unsafe Driving | Below 50% | Above 65% alert | −12% to +18% |
| HOS Compliance | Below 50% | Above 65% alert | −8% to +14% |
| Vehicle Maintenance | Below 60% | Above 80% alert | −5% to +12% |
| Crash Indicator | Zero crashes / 24mo | 2+ at-fault crashes | −10% to +35% |
| Drug & Alcohol | Active consortium | Missed tests | −3% to +20% |
Premium impact ranges based on aggregated rate filings from 2024–2026, owner-operator and small fleet segment.
Most carriers offer a 5%–10% credit at renewal for fleets that complete an annual safety self-audit and meet baseline program requirements. Tick all five and you usually qualify automatically.
Each documented training course unlocks a small per-driver credit. Stacking three or four can reach 12% off the schedule premium.
Five Keys defensive driving program. Industry-standard credit at most major trucking carriers.
Hours-of-service, hazmat, and cargo securement modules. Great for new fleets building their safety program.
DDC-PTD professional truck driver course. Often required after a preventable accident — file the certificate to recover credits.
Drag the sliders to model your stack. Result is indicative — your underwriter has the final say.
Discounts are typically applied multiplicatively, not additively. The calculator uses an additive simplification — a real binding quote can produce a higher or lower number depending on carrier rules.
Progressive Smart Haul has documented savings of up to $2,000 per truck per year for owner-operators with strong telematics behavior. Cover Whale and other carriers run similar programs with credits in the 8%–22% range.
Yes. Carriers pull CSA SMS data on every renewal. A clean Unsafe Driving and HOS profile typically saves 10%–15% versus a fleet operating with two or more alert thresholds exceeded.
Year one you cannot stack a CSA discount yet (you need 6+ months of inspection history), but you can lock in ELD telematics credits from day one and a safe-driver program credit if you have a clean MVR.
Carriers only ingest behavior aggregates — speed events, hard braking, hours-of-service compliance. They do not see individual loads or routes. For most owner-operators the $1,000–$2,000 annual savings outweighs the data sharing.
Within a single carrier, yes — ELD + safe driver + multi-policy + paid-in-full discounts can stack to 25% or more. The exact stacking rules vary, so an independent broker will model the best combination for your operation.
SafeBridge Insurance Group will model the full discount stack across 15+ carriers and put you with the one that pays you back the most.
