Should you press the clutch when i am on steep hill?

Yes, pressing the clutch when on a steep hill is important, especially if you're driving a manual transmission vehicle. It allows you to disengage the engine from the wheels, giving you better control when starting or stopping on an incline. However, be cautious not to hold the clutch down for too long to avoid unnecessary wear; instead, use the brake or engage the handbrake to prevent rolling back.
