What Is Full Coverage Car Insurance Insurance?
Full coverage combines New Jersey's mandatory liability insurance with optional collision and comprehensive coverage that protects your vehicle. Liability pays for damage you cause to others — required minimums are $15,000 per person and $30,000 per accident for bodily injury, plus $5,000 for property damage. Collision covers your car when you hit another vehicle or object. Comprehensive covers theft, vandalism, weather damage, and animal strikes.
- You rear-end a car at a red light, pushing it into the vehicle ahead. The first driver has $18,000 in medical bills; the second has $9,000 in vehicle damage. Your liability coverage pays the first driver up to your $15,000 per-person limit, leaving $3,000 unpaid unless you carry higher limits. It pays the second driver's $9,000 vehicle repair in full under your $30,000 per-accident bodily injury limit and $5,000 property damage limit. Your collision coverage pays to repair your own car, minus your deductible.
- A summer storm drops golf-ball-sized hail across your county. Your car sustains $4,200 in body panel and windshield damage while parked in your driveway. Comprehensive coverage pays the full repair cost minus your deductible — typically $500 or $1,000. Liability-only policies pay nothing for weather damage to your own vehicle. If you financed the car, your lender required you to carry comprehensive, so this scenario is covered.
- Your vehicle is stolen from a parking lot and never recovered. Comprehensive coverage pays the actual cash value of the car at the time of theft — not what you paid or what you owe. If the car was worth $11,000 and you owe $14,000 on the loan, comprehensive pays $11,000 minus your deductible, and you remain responsible for the $3,000 gap unless you carry gap insurance. Collision and liability do not cover theft.
Who Needs Full Coverage Car Insurance Insurance?
Full coverage is required if you finance or lease your vehicle — lenders mandate collision and comprehensive to protect their interest in the car. It is justified if your car is worth more than $5,000 and you cannot afford to replace it out of pocket after a total loss. Drivers in high-theft areas or regions with frequent hail, flooding, or deer strikes benefit from comprehensive even on older vehicles.
Calculate your car's actual cash value using Kelley Blue Book or a similar tool. Multiply your annual collision and comprehensive premium by three. If the three-year premium cost exceeds 50% of your car's value, consider dropping to liability-only and banking the premium savings. If you cannot replace the car without financing, keep full coverage regardless of age.
How Much Does Full Coverage Car Insurance Insurance Cost?
Adding collision and comprehensive to a liability-only policy in New Jersey typically costs $80–$150/month, or $960–$1,800/year, depending on your vehicle's value and your deductible.
- Vehicle value — a $35,000 car costs more to insure for collision and comprehensive than a $12,000 car because the potential payout is higher.
- Deductible selection — choosing a $1,000 deductible instead of $500 reduces your premium by 15–25% but increases your out-of-pocket cost per claim.
- Garaging zip code — urban areas with higher theft and vandalism rates, including Newark and Jersey City, carry higher comprehensive premiums than suburban counties.
- Driving record — at-fault accidents in the past three years increase collision premiums by 20–40% because you are statistically more likely to file another collision claim.
- Credit-based insurance score — New Jersey allows carriers to use credit history in pricing, and lower scores increase full coverage premiums more than liability-only premiums.
