What is the maximum speed limit on an open highway unless otherwise posted?

55 mph
60 mph
65 mph
70 mph

The correct answer is: 65 mph

The maximum speed limit on an open highway in Idaho is 65 mph unless otherwise posted. This regulation is designed to provide a balance between safety and efficiency for drivers traveling on less congested roads. Open highways often consist of rural areas where the traffic is lighter, allowing for higher speeds. By setting the limit at 65 mph, drivers can operate their vehicles at a reasonable speed that accommodates both the need for efficient travel and the safety of all road users. This speed limit is an important guideline that helps maintain consistent driving behavior and reduce the potential for accidents.
