When parking on a hill, your vehicle should always be left in what position?

Answer: C — Curb side perpendicular

When parking on a hill, your vehicle should always be left in a perpendicular position to the curb. Option A is incorrect because leaving the gear in park does not provide enough stability on a hill and could potentially cause your vehicle to roll. Option B is also incorrect as it is not necessary to park parallel to the curb on a hill. Option D is very dangerous as it eliminates any sort of braking system, which is necessary when parked on a hill. Therefore, option C is the safest and most appropriate position for parking on a hill.
