What must a driver do if they are involved in an accident while driving a commercial vehicle?

Answer: B — Notify authorities, provide assistance, and exchange information

When a driver is involved in an accident while operating a commercial vehicle, the primary responsibility is to notify authorities, provide assistance to anyone who may be injured, and exchange information with other parties involved in the accident. This ensures that all individuals involved are given the necessary support and that the situation is documented properly for legal and insurance purposes. Notifying authorities is crucial as they can assess the situation, document the scene, and ensure that any injured parties receive medical attention. Providing assistance reinforces the driver's responsibility towards others' safety. Exchanging information, such as insurance details, contact information, and vehicle registration, is important for aiding in the investigation and resolution of the incident. The other choices do not fulfill legal and ethical obligations. Continuing to drive without stopping avoids accountability and could worsen the situation for anyone who might need help. Simply exchanging information without notifying the authorities overlooks the necessity of formal reporting and can lead to legal complications. Lastly, waiting for help without reporting the accident fails to ensure that the proper procedures are followed, possibly leaving victims without assistance.
