How to Switch Truck Insurance Without Coverage Gaps
When Should You Start Shopping for New Truck Insurance?
Start comparing quotes 60 days before your renewal date. This gives you enough time to get competitive quotes, negotiate rates, and ensure a seamless transition with no coverage gaps. Waiting until the last week is the #1 cause of coverage gaps during carrier switches.
Step-by-Step Switching Timeline
| Timeline | Action |
|---|---|
| 60 days before | Start requesting quotes from multiple carriers. Provide current policy details, loss runs, and CSA data. |
| 45 days before | Compare quotes. Review coverage limits, deductibles, and exclusions — not just price. |
| 30 days before | Select new carrier. Begin application process. Request your current carrier provide loss runs (claims history). |
| 14 days before | New policy approved. Confirm effective date aligns with or precedes old policy expiration. |
| 7 days before | New carrier files BMC-91 with FMCSA. Verify filing at safer.fmcsa.dot.gov. |
| Day of switch | New policy starts. Old policy expires. Verify SAFER shows new carrier's BMC-91. |
| Day after | Confirm cancellation of old policy. Request refund for any unused premium. |
What Is BMC-91 Re-Filing?
Form BMC-91 is the proof of financial responsibility that your insurance company files directly with FMCSA. When you switch carriers, your new insurer must file a new BMC-91. Your MC authority stays active only if there is always a valid BMC-91 on file.
Processing time: 3-5 business days for FMCSA to update your record. This is why overlap is critical.
How to Avoid Coverage Gaps During the Switch
- Overlap by at least 1 day — your new policy should start 1 day before the old one expires. This ensures continuous BMC-91 coverage with FMCSA.
- Verify on SAFER — check safer.fmcsa.dot.gov to confirm the new BMC-91 shows up before canceling the old policy.
- Get written confirmation — ask your new carrier for written confirmation that BMC-91 has been filed.
- Don't cancel old policy early — let it run to expiration or until new coverage is confirmed.
Early Cancellation Penalties
Canceling your policy mid-term usually costs money:
- Short-rate cancellation: You pay a penalty of 10-25% of the remaining premium. The insurer keeps more than just the pro-rated amount.
- Pro-rata cancellation: You pay only for the time covered, with no penalty. This is the best scenario but not all carriers offer it.
- Minimum earned premium: Some carriers require you to pay at least 25-50% of the annual premium regardless of when you cancel.
Tip: The best time to switch is at renewal. You avoid all cancellation penalties, and carriers compete hardest for renewal business.
What Documents Do You Need to Switch?
- Current declarations page (shows your coverage and limits)
- Loss runs from current carrier (3-5 year claims history)
- USDOT and MC numbers
- CDL copies for all drivers
- Vehicle schedule (VIN, year, make, model, value for each unit)
- Current CSA scores

How do I verify my new BMC-91 is filed with FMCSA?+
Check your carrier's record at safer.fmcsa.dot.gov. Enter your USDOT number and look for the insurance section. Your new carrier's BMC-91 should appear within 3-5 business days of filing.
