During an in-cab check, which item must be pointed out and touched?

During an in-cab check, it is essential to point out and touch all gauges. This practice is crucial for ensuring that the driver has a comprehensive understanding of the vehicle's operational status and can monitor critical parameters such as speed, fuel level, engine temperature, and various warning lights. Gauges provide real-time information necessary for safe vehicle operation, and physically touching them reinforces the driver's awareness of their function and the importance of monitoring them during a drive.

While other options may include relevant components of the vehicle, they do not encompass the full range of instruments that the driver needs to actively engage with before operating the vehicle. Therefore, focusing specifically on all gauges highlights the importance of vehicle safety and readiness, making it the correct choice.
