Final answer:
The statement is true; you can be arrested for having open beer cans in the car due to open container laws, and for hitting someone with your vehicle, which could lead to charges such as vehicular assault or manslaughter.
Step-by-step explanation:
Driving with open containers of alcohol in a vehicle is illegal in most jurisdictions. If a person drives with an open beer can in the backseat and is stopped by the police, they can face legal consequences, including a possible arrest for violating open container laws.
Additionally, if during the same incident the driver hits an old lady, they could face far more serious charges, such as vehicular assault or even manslaughter, depending on the severity of the old lady's injuries. So, the statement that one could be arrested both for having open beer cans and for hitting an old lady is true. However, remember that driving under the influence and committing a traffic violation that results in harming someone carries severe legal repercussions and endangers lives.
