Final answer:
To start moving without rolling back on a hill, use the handbrake and release it slowly while applying the accelerator.
Step-by-step explanation:
To start moving without rolling back on a hill, you should use a combination of the handbrake and accelerator. The correct method is to keep the handbrake engaged and release it slowly while simultaneously applying the accelerator. This allows you to control the release of the brake and apply the necessary acceleration to start moving forward.
The correct option to start moving on a hill without rolling back depends on whether your vehicle has a manual or automatic transmission:
For a manual transmission: Option 3 is the correct choice. Depress the clutch, release it slowly while applying the accelerator, and smoothly transition to moving forward.
For an automatic transmission: Option 2 is typically the correct choice. Release the brake gently while applying the accelerator. Some automatic transmissions also have a feature called "hill hold" that helps prevent rolling backward.
It's important to note that the handbrake (parking brake) can also be used in combination with the appropriate technique to prevent rolling back on a hill. However, the specific method may vary depending on the vehicle and the transmission type. Always refer to your vehicle's manual for guidance on hill-start procedures.
