Always start your journey by the name of Almighty ALLAH.
Always drive on Petrol in low gear while going uphills.
Always drive in low gear while coming downhill.
I wouldn't recommend using 3rd gear while coming down.
Do not use break too much. keep your car in low gear to use engine resistance.
Do right use of indicators.
Never rush on hilly area. Better to be late than never.
Enjoy safe travelling
