To change the direction of travel on a **conventional road**, it is important to do so in a **suitable place**. This means that you cannot change direction just anywhere, as there are specific situations where it is prohibited:

- **Curves and hill crests** where visibility is limited.
- **Adverse weather conditions** such as fog or heavy rain.
- **Level crossings, tunnels, highways, and expressways**, unless there are designated places for it.
- **One-way roads and paths**.

Additionally, when making a change of direction, it must be done with a single turn of the vehicle and without using reverse gear, except in exceptional situations such as streets blocked by construction. It is crucial not to force other drivers to reduce their speed or put them in danger. If it is not safe, you should wait on the shoulder or continue until you find a safe place to perform the maneuver.

Therefore, the correct answer is that you can change the direction of travel, but **only in a suitable place**.
