To take a curve with **low visibility** safely, it is important to **drive as close as possible to the right edge of the road**. This is due to several reasons:

- **Safety in the curve**: By approaching the right edge, you reduce the risk of invading the opposite lane, which is crucial in curves with low visibility where you cannot see if another vehicle is coming in the opposite direction. This helps to avoid collisions.

- **Vehicle control**: Staying close to the right edge also allows you to have better control of the vehicle. If you take the curve too fast or in an incorrect position, you may be pushed into the opposite lane or off the road due to the centrifugal force acting in curves.

- **Visibility and lights**: In low visibility situations, such as at night, it is important that the vehicle driving on the inner part of the curve uses the appropriate lights to avoid dazzling other drivers. Staying on the right side helps to better manage the use of lights and avoid dazzling.

For these reasons, driving close to the right edge is the safest and most appropriate option when taking a curve with low visibility.
