- Why are MDT cameras only installed in certain locations?
- The department's primary reason for the cameras at various locations throughout the state is to aid our winter maintenance crews. These cameras are generally located in areas that are far removed from highway maintenance facilities. This saves our crews a great deal of time and expense by allowing them to observe road conditions at these remote locations without actually requiring them to drive there. Although this is the primary intended use of these cameras, we have also placed these images on the web for the benefit of the traveling public. We aim to add more cameras to mountain passes and other areas that experience extreme weather conditions as funding and resources become available.

- What is an open alcoholic beverage container?
- A bottle, can, jar, or other receptacle that contains any amount of an alcoholic beverage that is open or has a broken seal or the contents of which are partially removed or are immediately capable of being consumed.
- What is the major purpose of the law?
- The law prohibits unlawful possession of an open alcoholic beverage container by a person in a motor vehicle on a highway. Montana had the highest rate of alcohol related fatalities per vehicle mile traveled in the nation in 2002 and 2003 as reported by the National Highway Traffic Safety Administration. The open container law helps provide the message that it is not okay to drink and drive in Montana.
- Who gets the ticket?

- Yes, as long as the operator is a hired driver and has met the legal requirements of other public laws such as licensing requirements and local open container ordinances.

- Yes, in the living quarters of a camper, travel trailer, or motor home, the law allows a person to have an open alcoholic container.
