Your windshield is covered
Your windshield is covered under the comprehensive part of your policy.
If your insurance company refuses to cover your windshield under this part of your policy, they may be in violation of your policy as well as the law. You will however be required to pay whatever deductible that applies to your policy. However, you may adjust your deductible (before you have an issue). The difference in cost if you reduce your deductible on the comprehensive part is not as great as you may think. You are NOT required to have the same deductible on both your collision as well as your comprehensive.
