While driving, I was going about 25mph, but was coming to an intersection. Before getting to the intersection the light was blinking yellow due to the time so i started to slow down so i could yield through the light. At this time, my son who was 3yrs 2mo old (at the time) was in the backseat in his carseat. As I gradually stepped on the brake pedal, I then felt a big slam, and my face smacked the airbag and dust flew all over my vehicle, and son in the backseat who didnt have an airbag deploy. As I came to realize what happened my son was in the backseat screaming and i had smoke coming from my hood. I hit a city light pole outside of a 7-Eleven store. I was unsure of what happened that caused the accident, but after it happened I got out of my car in complete shock of what hit me. my son was in pullups, and the gel stuff inside the diaper had flew all over my car as it caused the seatbelt to tighten around his legs. I grabbed my son out of the car, because it was smoking and the first thing I should have done was not moved. When i got out of car to see what hit me, i stayed on the sidewalk and waited 35mins for a cop, so by the time the cop came, who never called ems, told me i was being cited and they took my vehicle to the impound lot. The car then was considered totalled and because I was in an accident, gasoline was leaking and they said it was considered hazardous. I didn't nor did my child receive medical attention because we did not have medical insurance at the tim
