oh my goodness!..........I'm a newly qualified driver (1 month alone) and i had my first signal reversion/irregularity the other day! had a single yellow turn to green in front of me, i then entered a 50 so took full power to get up to 45 to do my RBT............get half way through my RBT when i notice the signal ahead is at danger........slammed them in then i stop JUST before the red and as i stop i notice the signal is now flashing constantly between green and yellow! i contacted the signaller who then told me it was just showing a green on his panel so it must be a fault and he gave me permission to enter section etc. to say it put the wind up me is probably an understatement and i couldn't stop thinking about it all day!...........is it normal that i was thinking about it all day/reacted the way i did?? or was i overreacting and it's just a hazard of the trade?? thoughts?
