Which gear is best for waiting at a red light?

[Griffin]

When waiting at a red light, you can use neutral gear or parking gear. For automatic transmission vehicles, you can switch to neutral or parking gear while waiting at a red light. For manual transmission vehicles, you must shift to neutral gear when waiting at a red light because manual transmission vehicles do not have a parking gear. For automatic transmission vehicles waiting at a red light, you can operate as follows: 1. If the expected waiting time is less than 30 seconds, keep the gear in D (Drive) and apply the foot brake. 2. If the expected waiting time is more than 30 seconds, shift to N (Neutral) and apply the handbrake. 3. If the expected waiting time is more than 2 minutes, shift to N (Neutral), apply the handbrake, and turn off the engine.
