I’m pretty sure I’m in the right but please let me know if something has changed.
Driving along a dual carriage way at 70. Petrol station and a young women decided to speed up coming on from the petrol station and just pull in front of me, I had to slam on my breaks. There was a car waiting to pull in but she went round them and just joined the carriage way.
She then flipped me off so I wasn’t too grown up and sounded my horn and flipped her off too.
I was always taught that people on the dual carriage way have right of way and it’s a give way basically. You wait till it’s clear to join.
