Is it less likely to stall when using air conditioning during the test?

[LeNathan]

This is the case because after turning on the air conditioning, the engine will automatically increase the idle speed to ensure the operation of the compressor. Although this reduces the chance of stalling, the vehicle speed will also increase accordingly. To avoid stalling or rolling back, it is essential to apply throttle during hill starts. During practice, you can use the foot brake instead of the handbrake to train the coordination between the throttle and clutch. 1. Reasons for rolling back: The phenomenon of rolling back occurs in the driving test because the clutch contact point is not lifted sufficiently. If no throttle is applied, it is likely that the idle speed is insufficient to drive the car to start on the slope, resulting in stalling. 2. Reasons for stalling: Stalling occurs when braking or lifting the clutch in a hurry after rolling back. It could also be because the handbrake was released too late during the start.
