Frequently asked questions
What does “full coverage” really mean?
There's no single "full coverage" policy — it usually means liability plus collision and comprehensive. An agent can explain which coverages fit your vehicle and budget.
What happens if my coverage lapses?
Many states penalize insurance lapses on registered vehicles, including registration suspension and fees. If you're switching carriers, an agent can line up effective dates so there's no gap.
Will adding a teen driver change my options?
Often, yes. Independent agents can re-shop the household across carriers when drivers or vehicles change.
