How should you secure the cab when parked to prevent unauthorized access?

• A. Leave the cab door open for ventilation and keep the parking brake unset.
• B. Close and lock the cab door, set the parking brake, and ensure all controls are secured in a safe position.
• C. Turn off the cab and leave all controls in their last position.
• D. Remove the keys and leave the parking brake disengaged.

Answer: (B)

Securing the cab when parked is about preventing unauthorized access and accidental movement. The best approach is to close and lock the cab door so no one can enter, set the parking brake to keep the vehicle from moving, and ensure all controls are secured in a safe position so nothing can be operated accidentally. Leaving the door open would invite tampering, and leaving the brake off or controls left in a last position could allow movement or unintended operation, which is unsafe.
