Apart from a lower special-condition rule, what ordinary maximum speeds apply where no different limit is posted in a Maine business or residential district or built-up portion, and on other public ways?

Correct answer: 25 mph in the district or built-up portion and 45 mph on other public ways

Why

Unless posted otherwise, the ordinary maximum is 25 mph in a business or residential district or built-up portion and 45 mph on other public ways. A built-up portion has structures less than 150 feet apart along the way for at least one-quarter mile. Separate 15 mph provisions apply to specified school activity and legally obstructed intersections. Always drive at a careful, prudent speed for actual conditions; a numerical maximum is not a command to maintain that speed.
