After stopping for a lengthy time, you wish to continue driving. What should you do?

The chosen combination is correct and complies with German traffic regulations, which emphasize the importance of safety before continuing to drive after a stop.

1. Checking for children under the vehicle is crucial as it helps prevent accidents. Children can be hard to see, especially in larger vehicles, and ensuring they are clear of your vehicle is a critical safety measure.

2. Performing a visual inspection of the vehicle's condition is important to ensure that there are no mechanical issues that could affect safe operation. This includes checking for any irregularities or damages that might have occurred during your stop.

3. Ensuring that the load is secure is vital for safe driving, as an unsecured load can shift unexpectedly, impacting vehicle control and posing dangers to you and other road users.

These steps are all essential to promoting safety and are in line with the German road traffic regulations aimed at preventing accidents and ensuring responsible driving.
