I was involved in a single vehicle accident due to a medical issue. I hit a utility pole, took out a cyclone fence, proceeded across a front yard of a home then almost directly into a block retaining wall. I was wearing my seat belt. My airbags did not deploy but I have no idea how fast I was going. From the damage to the pole and the wall and my truck I had to be going a decent speed. The police report noted that when they arrived my foot was on the accelerator and the back wheels were spinning for what thatâs worth.
