To enter a curve safely, it is important to choose an **appropriate speed** that allows you not to brake throughout the turn. This is because, when taking a curve, a force is generated that can push the vehicle out of the desired path, especially if driving at high speed.

- **Dangerous curves:** Curves are more dangerous when they are very tight, the vehicle is heavily loaded, or traveling very fast. In these situations, the vehicle may continue straight and leave the road or invade the opposite lane.

- **Appropriate speed:** This is a speed that adjusts to the weather conditions, the road, the vehicle, and the driver's state. Driving at an appropriate speed allows for better control of the vehicle in unforeseen circumstances and reduces the likelihood of serious accidents.

- **Speed limits:** Although there are established speed limits for different types of roads, the appropriate speed in a curve may be lower than these limits to ensure safety. For example, on non-urban roads, the limit may be 90 km/h, but on a tight curve, a lower speed might be safer.

In summary, the key is to adjust the speed before entering the curve to avoid the need to brake during the turn, which helps maintain control of the vehicle and prevent accidents.
