Gently turn the steering wheel and slowly straighten it to avoid excessive correction, which can prevent the turn signal from springing back. After straightening the steering wheel, flick the turn signal once more before it springs back to prevent it from doing so. If you don't straighten the steering wheel, you can hold the turn signal to prevent it from returning to its original position. When performing specific maneuvers, push the turn signal all the way down to prevent it from springing back and ensure it remains in the alert state. While driving, manually operate the turn signal to prevent it from springing back and ensure it functions properly.

The key to preventing the turn signal from snapping back during the Subject 2 driving test lies in technique and timing control. When activating the turn signal, use your knuckles to brace against the steering wheel, and don’t rush to remove your hand from the control lever after turning it on—wait until the steering wheel begins to turn before slowly releasing. Particularly in maneuvers like exiting a parallel parking spot, where the steering wheel returns quickly, anticipate the rebound force in advance and use your left hand to gently hold the lever for at least three seconds. During practice, I noticed that the turn signal tends to snap back when the steering wheel turns beyond 90 degrees, so extra attention is needed to stabilize the switch during minor turns. It’s advisable to have your instructor observe from the passenger seat during training, correcting muscle memory immediately if the signal snaps back.

When I first started learning to drive, I also got tricked by the turn signal lever snapping back a few times. Later, I figured out a trick: when signaling, keep your palm against the side of the steering wheel and use your thumb and index finger to pinch the lever, pressing it all the way down. Don't apply too much force when turning the steering wheel; when you feel it starting to return to center, gently support the lever with the back of your hand. Pay special attention to maneuvers like 90-degree turns—signal early before entering the turn, and when exiting, use your palm to shield the switch to prevent it from snapping back. During normal S-curve practice, deliberately count '121' when the steering wheel returns to center to keep the signal on, building muscle memory so you won't forget easily.

The turn signal resets mainly because the steering wheel automatically returns to center, triggering the switch. Remember three key points when operating: ensure you hear the 'click' sound when activating the signal; keep your hand on the lever while turning the steering wheel; and avoid returning the wheel too quickly, especially during sharp turns like exiting parallel parking. During practice, mentally rehearse the 'signal-turn-look-cancel' four-step sequence each time you change lanes, and only cancel the signal after fully entering the new lane. Exam vehicles usually have more sensitive steering columns, so prioritize practicing this during mock tests.

To prevent the turn signal lever from snapping back, adapt to your vehicle's characteristics. With loose steering wheels in driving school cars, it's advised to half-wrap your palm around the lever base after signaling, using the thumb-index notch to secure it during turns. During hill starts, keep your right hand supporting the signal switch while steering with the left. Listen carefully for the turn signal click sound during tests - if the ticking suddenly stops, reactivate it immediately. During practice, ask fellow trainees to monitor your turn signal status and remind you to adjust hand positioning promptly.

During my time as a driving instructor at the driving school, I noticed a common mistake among students: applying too little force when activating the turn signal. The correct technique is to have the palm facing upwards, press the signal lever with the second joint of the index finger while the other four finger joints brace against the steering wheel spoke. The lever is most prone to spring back when the steering wheel is turned within 45 degrees, so it's crucial to support the switch base like holding a teacup during such turns. Focus on practicing the curve driving exercise, treating the signal lever as an extension of the steering wheel at every bend. Once this becomes habitual, you won't fumble during the test.
