Newly Acquired Vehicles:
If you buy a new vehicle, it is generally covered under your existing auto insurance provided that: (1) all of your vehicles are insured by the same company; and, (2) so long as you add the vehicle to your policy within 30 days of the date you acquire it. You will have the same coverage(s) as with your existing vehicle(s), so it is important that you consider adding additional coverages such as collision, or increasing your limits, when you trade in an older vehicle for a newer, more valuable one.
Temporary Substitute Vehicles:
This coverage can vary greatly. Generally, a vehicle that is temporarily being used because of a breakdown or servicing of an insured vehicle will be insured under your auto policy. A rental vehicle will often, but not always, qualify as a temporary substitute vehicle. Be sure to check your policy for what coverage applies to your use of a rental car. Also, remember that vehicles which are provided to you for your work by an employer are almost never covered under your personal auto policy, so be sure that your employer has insurance in place on the work vehicle. If you regularly drive a vehicle provided by your employer, ask them to maintain UIM coverage on the vehicle, as usually your own UIM coverage will not apply to a work vehicle not owned by you. If the employer does not have UIM coverage on the work vehicle, ask them to add it. If your employer cannot provide UIM coverage, you can typically buy your own endorsement to add UIM coverage to a vehicle you don’t own, and should do so.
