Is it okay to wait at a red light in first gear with the clutch pressed?

Waiting at a red light in first gear with the clutch pressed is not recommended, as it can cause severe damage to the clutch. If the wait time is long, you should shift to neutral and engage the handbrake. Manual transmission starting tips: When the countdown is less than 10 seconds, shift into first gear, press the clutch, and apply the foot brake. When the light turns green, start quickly. Automatic transmission starting tips: The gear selection while waiting at a red light depends on the duration of the wait. If it's less than 30 seconds, simply pressing the brake while remaining in D (Drive) gear is sufficient. For waits longer than 30 seconds, shifting into N (Neutral) is a more reasonable choice. On an incline, engaging the handbrake prevents fatigue from prolonged brake pressing and avoids dazzling the vehicle behind with brake lights.
I've been driving manual transmission cars for ten years, and I often engage first gear and press the clutch at long red lights. It's fine for short durations, like red lights under ten seconds, as it allows for a quicker start. However, if the red light lasts more than half a minute, doing this makes the ankle particularly sore, and the clutch release bearing remains under constant pressure, leading to premature wear. What's even more concerning is that if the foot slips when the mind is relaxed, the car might lurch forward, causing a rear-end collision. Nowadays, I've developed the habit of shifting to neutral and applying the handbrake if the red light exceeds ten seconds, with my right foot lightly resting on the brake pedal. This not only reduces foot fatigue but also minimizes strain on the clutch and transmission. When starting on a slope, it's necessary to engage first gear, press the clutch, and coordinate with the handbrake, but on flat ground at a red light, it's really not necessary. Remember, protecting the clutch saves money—replacing a release bearing requires dismantling the transmission, and the labor costs are quite high.
From a mechanical perspective, holding the clutch pedal down while in first gear at a red light is not an ideal operation. When the clutch is depressed, the release bearing continuously operates, generating frictional heat, which accelerates wear over time. Especially during long red lights exceeding 90 seconds, this is equivalent to dry grinding the bearing under high temperatures. Moreover, with the transmission in first gear, although the gears are not engaged, the entire drivetrain remains in standby mode, causing unnecessary wear. In contrast, shifting to neutral allows the drivetrain to completely disconnect and rest. Additionally, prolonged clutch pedal depression can lead to increased temperature of the hydraulic fluid, potentially affecting the lifespan of sealing components. I recommend developing the habit of checking the countdown timer; if it exceeds 15 seconds, decisively shift to neutral and keep your right foot on the brake for greater stability.
