The answer to your question varies from one company to the next. Companies handle it differently. Some will allow you to suspend coverage, others will not. Some companies might require a valid reason to suspend coverage (such as military deployment). Some companies also offer "storage" status, in which all coverages are suspended except for comprehensive coverage.
But again, you need to ask your agent or company about how they handle this because they all handle it differently.

This will vary by company. Some insurance providers will let you put your autos in suspense meaning the policy would be reduced to physical damage only and can not be operated on the road. You would pay a minim premium on your auto while parked and the vehicle would still be covered in the event of a potential theft or fire for example. I recommend you discuss this with your agent.
