Do I have to pay a deductible if I hit someone but my vehicle is not damaged?

I rear ended a guy on a highway on-ramp. Damage is negligible, but he’s filing a claim. Do I have to pay for a deductible or anything?

You only have to pay a deductible when your collision or comprehensive coverage pays for damages to your vehicle after filing a claim, so no, you will not need to pay a deductible in this case. I also recommend reading this article regarding claims to see how this will impact your rate. If you have any further questions, don't hesitate to ask.
