There is a tunnel on my route. What should I know?

Your answer is correct. When approaching or driving through a tunnel, you should know how to act if you need to stop and leave your vehicle due to a breakdown or emergency—that includes knowing how to park safely and exit your vehicle. It's also essential to know how escape routes are marked in tunnels, so you can find them quickly if needed. However, it is not guaranteed that help will arrive immediately in an emergency, so you must be prepared to act independently. This knowledge is important for your safety and the safety of others when using tunnels.
