On my last trip to Scotland, I was driving from Isle of Skye to Inverness at night at considerable speed on a single carriage way 140+, a herd of deer just jumped in middle of the road and upcoming bridge and river making it worst to avoid deers as i cant go off road and straight to river! just to give you an idea it was like this
==========vvvvvv=====BRIDGE-BBBBBBB============
--CAR>----------DEERS----------------------------------------------
===================BRIDGE-BBBBBBB=============
good thing deers stopped because of car lights, and no on coming vehicle, so i moved right and immediate left to be on bridge! I had two little one on back seats along with my wife - all three sleeping, on passenger seat my sister who was awake! Children were safe as in children seats and all buckled up! Wife had scary wake up as she wasnt wearing seat belt. split seconds Allah saved us all as after right left at high speed car was swerving after that until it was stopped! but if we were in a bit lighter car it would have been a disaster, car was a rental almost brand new 2.0 CDTi GM/Vauxhall/Opel Insignia and stood its ground and behaved well though i believe at one point its left side was in the air for nano seconds!
It cant be compared to earlier on same day i came across sheeps on a bendy road but at very low speed and at day time!
So stay alert, all seat belts and correct children car seats in case of children in the car!
