Final Answer:
A motorist has three choices if their vehicle is about to hit something: 1) Swerve to avoid the object, 2) Brake hard and stop, and 3) Apply the horn to warn others. option 1, 2 and 3 are answer.
Step-by-step explanation:
When a motorist faces a potential collision, their response depends on the specific circumstances. Swerving to avoid the object is a viable option if there's enough space to maneuver safely without risking other obstacles or vehicles. If swerving isn't practical, the motorist can choose to brake hard and attempt to come to a stop, minimizing the impact force. Additionally, applying the horn can serve as a warning signal to alert pedestrians or other drivers to the impending danger.
In summary, a motorist should evaluate the situation and choose the most appropriate response from the three options. Therefore, option 1, 2 and 3 are answer.
