I am so stressed so bare with me. Going down the A1 but it’s a single carriageway and turning right into a little side road because I live there. I stop and start Indicating right as there is approaching traffic on other side of the road. I can see a white van approaching my rear at high speed but I still don’t want to turn as there is traffic coming very quickly on other side of road. Then I see a gap but I am really stressed at this point and I stall my car like an absolute fool. So embarrassed. Crash. He goes into the back of me and he was absolutely raging. His van is damaged worse than my car, I have some damage to my bumper but managed to drive home.. I’ll be found at fault for, won't I?
