In New Jersey you are responsible for your deductible and co-pay. The basic policy has a $250 deductible and a 20% co-pay up to $5,000. Therefore, the maximum amount of out-of-pocket expenses you will incur under the basic policy is $1200. There are also higher deductible amounts that you can choose which will increase your out-of-pocket expenses. In those cases your deductible can be as high as $5000. You are responsible for the co-pay and deductible and not the person that caused the collision. However, you can submit any unpaid deductible and co-pay to your private insurance company for payment.
