What Is Full Coverage Insurance?
Full coverage combines three separate coverages into one package: liability (required by Arizona law), collision (pays for your vehicle damage regardless of fault), and comprehensive (pays for non-collision damage like theft, hail, or vandalism). Lenders require this package when you finance or lease a vehicle because they hold the title and need assurance the asset is protected. Once you pay off the loan, the collision and comprehensive components become optional — you keep liability because Arizona mandates it, but you decide whether the physical damage coverages still justify their cost.
- You rear-end a car at a stoplight in Phoenix. The other driver has $9,000 in vehicle damage and $14,000 in medical bills. Your liability coverage pays the $23,000 total (within your policy limits). Your collision coverage pays to repair your own vehicle, minus your deductible — typically $500 to $1,000. Without collision, you pay the full repair cost out of pocket.
- A summer monsoon drops golf-ball-sized hail across Tucson, causing $4,200 in dent and glass damage to your parked sedan. Comprehensive coverage pays the claim minus your deductible. Collision doesn't apply because no other vehicle was involved. Liability doesn't apply because you caused no damage to others. If you dropped comprehensive to save $30/month on a paid-off car, you now pay the full $4,200.
- An uninsured driver runs a red light and totals your vehicle. The at-fault driver has no coverage and no assets. Your collision coverage pays your vehicle's actual cash value minus your deductible — you're made whole. Without collision, you file under uninsured motorist property damage if you purchased it, or you sue the at-fault driver and likely collect nothing. This scenario reveals why many Arizona retirees keep collision even on paid-off vehicles — uninsured driver rates run 12-13% statewide.
Who Needs Full Coverage Insurance?
Retirees still paying off a vehicle loan or lease have no choice — the lender mandates full coverage to protect their collateral interest. Retirees driving paid-off vehicles worth $8,000 or more should keep collision and comprehensive if Arizona's 12-13% uninsured driver rate concerns them, or if they lack liquid savings to replace the vehicle after a total loss. Drivers in monsoon-prone Tucson or theft-heavy Phoenix metro ZIP codes often find comprehensive worth keeping even on older vehicles.
Calculate your vehicle's actual cash value using Kelley Blue Book or NADA guides. Add your annual collision and comprehensive premiums. If premiums exceed 10-15% of the vehicle's value, or if you have liquid savings equal to the replacement cost, consider dropping physical damage coverage and keeping only Arizona's required liability minimums plus uninsured motorist coverage. Revisit annually as the vehicle depreciates and your savings position changes.
How Much Does Full Coverage Insurance Cost?
Full coverage typically adds $80-$150/month compared to liability-only coverage in Arizona, though costs drop significantly for retirees qualifying for low-mileage and mature-driver discounts.
- Vehicle age and actual cash value — premiums on a 12-year-old sedan often approach the vehicle's depreciated worth, making collision and comprehensive poor value propositions.
- Deductible selections — choosing a $1,000 deductible instead of $500 lowers premiums 15-20% and makes sense for retirees with emergency savings who drive infrequently.
- Annual mileage — Arizona carriers offer substantial discounts for drivers logging under 7,500 miles per year, a threshold most non-commuting retirees meet easily.
- Garaging ZIP code — metro Phoenix and Tucson show higher comprehensive claims from theft and monsoon damage than rural Arizona counties.
- Mature-driver course completion — carriers writing in Arizona voluntarily file discounts of 5-10% for drivers 55+ who complete state-approved defensive driving courses, though this is not an Arizona mandate.
- Multi-policy bundling — pairing auto with homeowners or renters coverage through one carrier typically reduces combined premiums 10-15%.
