Yes—right turns on a red light are legal in California as long as you come to a complete stop before entering the intersection and yield to other vehicles. That is, unless there's a posted sign prohibiting the turn.May 31, 2022
You must yield the right-of-way to any police vehicle, fire engine, ambulance, or other emergency vehicle using a siren and red lights. Drive to the right edge of the road and stop until the emergency vehicle(s) have passed. However, never stop in an intersection.
不对，打开的酒精饮料，不管放哪都是违法。Ref：In California, it is illegal to have any “open” container of alcohol in your vehicle. This is true regardless of whether you are drinking it and even if there is no longer any alcohol in the container. If police find any open container in your car when they pull you over, you can be charged under VC 23222.
