You should not ___________________ if you go off the pavement.

The correct choice indicates that it is not advisable to swerve if you find yourself off the pavement. When a driver goes off the roadway, they may experience a loss of control due to uneven terrain, different surface traction, or an unexpected situation. Rapidly turning the steering wheel can lead to overcorrection, potentially resulting in a rollover or colliding with obstructions or oncoming traffic. Maintaining a steady path and avoiding sudden movements can help the driver regain control and safely return to the pavement.

Driving slowly may actually help in regaining control, while stopping abruptly can also be a danger if there are vehicles behind you, leading to potential collisions. Honking the horn may alert others, but it doesn't address the immediate need for safe maneuvering. Thus, avoiding any rapid or sudden turning movements is crucial for safety in this context.
