You can cancel a car insurance policy at any time. In many cases, you might be eligible for a partial or even a full refund of any advance premiums you've paid. While some providers might require a written notice or cancellation form, others might just need a simple phone call.
However, we recommend doing a bit of homework before making such decisions to ensure you don't inadvertently create a gap in your coverage. A coverage lapse could potentially mean higher premiums down the road. With a bit of foresight and planning, you can sidestep issues like overlapping coverage, unnecessary extra fees and, most importantly, any gaps in your car insurance coverage.
