Can you cancel car insurance policy?

Yes, either by contacting the insurer or the agent to cancel it, or by not paying the next premium when due. However, most states require auto insurance as a condition of registering the vehicle and renewing your driver's license. Therefore, if you have no applicable coverage when you try to do either, problems will arise.

Further, if you are involved in a collision that is your fault and do not have liability insurance, you may be personally liable for the other party(ies) damages. In turn, if you are sued for those damages and a judgment is entered against you, the Financial Responsibility Laws of most states dictate that your license will be suspended until payment of the damages is arranged. You are generally also required to obtain an SR-22 which is a type of high risk liability insurance and to maintain it for a stated period of time provided by statute.
