Starting from a stop on a hill with a manual car can be challenging. A hill can cause you to roll backward when you take your foot off the brake.
The best way to start on a steep hill is to use the hand brake to keep your car from rolling back as you press on the accelerator and take your foot off the clutch. You will need to give the car more gas than normal to get enough momentum to go up the hill.
Don’t use your clutch to hold your car in position on a hill. This can put a lot of wear on your clutch!
