Lesson 18 of 26 · Section 8: Managing Time and Space

Speed limits and school zones

Posted limits do not tell you what speed you must drive, only that you cannot go faster, and you must slow down when conditions make them unsafe. Maine sets limits of 45, 25 and 15 mph unless posted otherwise and doubles fines for speeding in school zones.

3 questions from the Maine practice test

  1. 1. What maximum speed applies when passing a school during recess in Maine, unless a different limit is posted?

    1. 35 miles per hour
    2. 25 miles per hour
    3. 15 miles per hour
    4. 45 miles per hour
    Show answer

    15 miles per hour. Maine sets a 15 mile per hour maximum when a driver passes a school during recess, or when children are traveling to or from school during opening or closing hours. The 25 mile per hour figure belongs to business, residential, and built-up areas, so it is the most plausible but incorrect substitute here. A posted limit still controls when one is lower or otherwise specific. The practical cue is the school setting and the timing: slow to 15 mph during recess or the listed arrival and departure periods, and use extreme care when the exact period is uncertain.

  2. 2. Unless posted otherwise, what is the maximum speed outside any business, residential, or built-up area in Maine?

    1. 25 mph
    2. 45 mph
    3. 55 mph
    4. 65 mph
    Show answer

    45 mph. Maine's default maximum is 45 miles per hour outside business, residential, or built-up areas, unless a different limit is posted. Twenty five mph is the default inside a business district, residential district, or built-up area. Fifty five and 65 mph are not among the unposted default maximums the handbook lists, so they apply only where a sign sets them. Conditions can still require a slower speed than the default.

  3. 3. In a Maine school zone, how does the handbook define school opening and closing hours for the 15 mph limit?

    1. One hour before the school day starts to one hour after it ends
    2. Only while a crossing guard is present
    3. The whole school day, from 7 a.m. to 4 p.m.
    4. Half an hour before the school day starts to half an hour after it ends
    Show answer

    Half an hour before the school day starts to half an hour after it ends. A five sided school sign means you must slow to 15 mph during recess, when children are going to or leaving school, and during opening or closing hours, which run from half an hour before the start of the school day to half an hour after the end. One hour is twice the stated window. A crossing guard is not required for the limit to apply, and the handbook sets no fixed clock hours. Exceeding the posted limit in a school zone brings twice the usual fine.
