I had this exact worry when training with PSTT as coming from Norfolk, traffic really doesn’t tend to be a problem living out in the sticks and I honestly have never seen anything like it in terms of the amount of cars parked at sides of roads as there is around Sutton-In-Ashfield where they’re based.
I was panicking about being either too hesitant or over confident and causing a hazard for someone else. You’ve just got to error on the side of caution but not too much. I ended up with 1 minor for hesitation where the examiner said he thought he could have made it bud understood why I held back.
Just remember if you hesitate, it’s a minor whereas if you are over confident and cause someone else to have to take evasive action, it’s an instant fail.
Good luck with it
