What should you consider after starting your vehicle?

You chose the correct answers. After starting your vehicle, you should drive off as promptly as possible and drive at low engine speeds. Modern engines do not require idling to warm up; letting the engine run while stationary wastes fuel and creates unnecessary emissions. Instead, you should begin driving soon after starting and keep engine revs low to allow the motor to reach operating temperature efficiently and with minimal wear. This approach is environmentally friendly and better for the engine's longevity. Letting the car idle to warm up, as suggested in the third answer, is not recommended under German traffic rules.
