Which of the following is required by Alaska law for vehicle owners or drivers?

In Alaska, it is a legal requirement for vehicle owners and drivers to maintain an automobile liability insurance policy. This law ensures that drivers are financially responsible for any damages or injuries they may cause while operating their vehicles. Liability insurance helps protect other drivers, pedestrians, and property owners in the event of an accident, providing coverage for medical expenses and property damage.

Having liability insurance is critical for safe driving practices and promotes accountability on the roads. In this way, it functions as a safeguard for the public and contributes to overall road safety. The requirement reflects the state's commitment to minimizing the financial burdens that can arise from vehicle accidents.

While the other options mention aspects related to vehicle operation, such as carrying passengers, having a functioning horn, or performing regular maintenance, they are not mandated by law in the same way that having liability insurance is. Therefore, maintaining an automobile liability insurance policy stands out as a specific legal obligation for all vehicle owners and drivers in Alaska.
