What should you do before making a sudden stop?

Answer: B — Brake lightly to warn other drivers

Before making a sudden stop, braking lightly serves as a warning to other drivers. This action helps to alert those behind you that you are slowing down or coming to a stop, which is crucial for maintaining safety on the road. When you brake lightly, the brake lights activate, providing visual cues to other drivers that a change in speed is occurring. This can prevent potential collisions from vehicles following too closely, as they have an opportunity to react to your decreasing speed. Using this method fosters better communication with other road users, enhancing overall traffic safety. Establishing a practice of signaling your intentions through braking can help prevent accidents and ensure that everyone on the road can anticipate your actions.
