To drive safely on a curve, it is essential to **adjust the speed to the characteristics of the curve**. This is because curves are dangerous sections of the road where a force is generated that can push the vehicle out of the curve if driving at an inappropriate speed.

- **Before entering the curve**, it is important to reduce speed or brake if necessary. This helps control the vehicle and prevent centrifugal force from pushing it to the outside of the curve.

- Curves are especially dangerous when they are very tight, the vehicle is heavily loaded, or traveling very fast. In these situations, the risk of the vehicle continuing straight and leaving the road or invading the opposite lane increases.

- **Within the curve**, it is crucial to turn the steering wheel smoothly and avoid braking or accelerating abruptly. This maintains the stability of the vehicle and allows for more precise control.

- **Upon exiting the curve**, you should gently turn the steering wheel to return to straight driving and gradually increase speed.

Therefore, adjusting the speed according to the characteristics of the curve is essential to maintain vehicle control and ensure road safety.
