To tow a crashed or broken-down vehicle, it is necessary to use a **tow truck**. This type of vehicle is specifically designed for this task, as it has the equipment and features necessary to safely hitch and transport another vehicle that cannot move on its own.

- **Tow trucks** and other types of vehicles are not designed to tow crashed or broken-down vehicles. These vehicles may be equipped to transport loads or trailers, but they do not have the specific features of a tow truck, such as the proper hitching and lifting system for broken-down vehicles.

- A **tow truck** is a special type of vehicle that can lift and tow other vehicles, ensuring that the process is safe for both the towed vehicle and other road users.

Therefore, only a **tow truck** is suitable and legally permitted to tow crashed or broken-down vehicles.
