Driving on **ice** is very dangerous because the vehicle's wheels have less grip, which increases the risk of the vehicle skidding. In these conditions, it is crucial to **avoid stepping on the brake**. Braking abruptly can cause the wheels to lock and the vehicle to lose control, especially if it does not have an ABS system (anti-lock braking system).

- **Do not brake**: In skidding situations, such as when the vehicle skids on ice, it is important not to brake. Braking can worsen the skid and make the vehicle more difficult to control.

- **Drive smoothly**: It is recommended to gradually reduce speed and avoid sudden movements with the steering wheel. This helps maintain control of the vehicle and prevent skids.

- **Maintain a safe distance**: Because the vehicle needs more space to stop on slippery surfaces, it is essential to maintain a greater safe distance from other vehicles.

In summary, when driving on ice, it is preferable to avoid stepping on the brake to maintain control of the vehicle and reduce the risk of accidents.
