Occurrence vs claims-made: which form should Engineering Firms buy on Commercial Auto?

Occurrence and claims-made are two different ways an Commercial Auto policy "triggers" — meaning, decides whether a claim is covered.

• Occurrence: the policy responds to claims arising from events during the policy period, regardless of when the claim is filed. A claim filed 5 years after the event is still covered by the policy in effect when the event occurred.
• Claims-made: the policy responds to claims filed during the policy period (regardless of when the event occurred), provided the event happened after the retroactive date. The policy must remain in force for coverage to apply.

For Engineering Firms on professional services firm risks, occurrence is generally preferred for liability lines because losses can take years to surface. Claims-made requires careful retroactive date and tail coverage management.

How Engineering Firms manage the retro date on Commercial Auto

The retroactive date on a claims-made Engineering Firms Commercial Auto policy is functionally a "coverage starts here" marker. Move the retro date forward (closer to today), and you cover less prior exposure. Move it back (earlier), and you cover more.

Carriers sometimes try to advance the retro date at renewal, especially after a claim. Resisting this is important — accepting a later retro date trades long-tail coverage for short-term premium savings, often a bad bargain.

How Engineering Firms handle the end of a claims-made Commercial Auto policy

When a claims-made Commercial Auto policy terminates (non-renewal, cancellation, carrier change, business sale), the engineering firm loses the ability to file claims under that policy. Tail coverage — also called Extended Reporting Period (ERP) — preserves the ability to file claims after termination for events that occurred during the policy period.

For Engineering Firms, the standard tail is 1-3 years; some policies offer unlimited tails. Cost is typically 100-250% of the final annual premium for the full tail period. Planning for tail coverage at every claims-made policy transition is essential to avoid uncovered exposure.

Broad form vs basic form: what Engineering Firms should know on Commercial Auto

For most Engineering Firms, the marginal premium for broader coverage is well worth it. Special form on property and inland marine has become the default for good reason — the unenumerated risks the form covers are exactly the surprises that produce claim-time disputes on basic forms.
