When you have auto insurance, one of the elements of your coverage that you have control over is the amount of your deductible. Your deductible is what you have to pay before your insurance company will step in and cover the rest of the damage to your vehicle. Deductibles apply to both your comprehensive and collision coverage.
You can go with a lower deductible, or you can opt for a higher deductible. Generally, if you go with a lower deductible, the cost of your premium will increase, and if you go with a higher deductible, the cost of your premium will decrease.
