     § 3365.  Special speed limitations.        (a)  Bridges and elevated structures.--            (1)  No person shall drive a vehicle over any bridge or        other elevated structure constituting a part of a highway at        a speed which is greater than the maximum speed which can be        maintained with safety to the bridge or structure when the        structure is posted with signs as provided in this        subsection.            (2)  The department and local authorities on highways        under their respective jurisdictions may conduct a traffic        and engineering investigation of any bridge or other elevated        structure constituting a part of a highway, and if it shall        thereupon find that the structure cannot safely withstand        vehicles traveling at the speed otherwise permissible under        this title, the department or local authority shall determine        and declare the maximum speed of vehicles which the structure        can safely withstand, and shall cause or permit official        traffic-control devices stating the maximum speed to be        erected and maintained before each end of the structure.            (3)  Upon the trial of any person charged with a        violation of this subsection, proof of the determination of        the maximum speed by the department and the existence of the        signs shall constitute conclusive evidence of the maximum        speed which can be maintained with safety to the bridge or        structure.        (b)  School zones.--When passing through a school zone as     defined and established under regulations of the department, no     person shall drive a vehicle at a speed greater than 15 miles     per hour. An official traffic-control device shall indicate the     beginning and end of each school zone to traffic approaching in     each direction. Establishment of a school zone, including its     location and hours of operation, shall be approved by the     department.        (c)  Hazardous grades.--The department and local authorities     on highways under their respective jurisdictions may conduct     traffic and engineering investigations on grades which are     considered hazardous. If the grade is determined to be     hazardous, vehicles having a gross weight in excess of a     determined safe weight may be further limited as to maximum     speed and may be required to stop before proceeding downhill.     The restrictions shall be indicated by official traffic-control     devices erected and maintained according to regulations     established by the department.        (c.1)  Active work zones.--When passing through an active     work zone, no person shall drive a vehicle at a speed greater     than the posted limit. An official traffic-control device shall     indicate the beginning and end of each active work zone to     traffic approaching in each direction.        (d)  Penalty.--            (1)  Any person violating any provision of this section        commits a summary offense and shall, upon conviction, be        sentenced to pay:                (i)  Except as set forth under subparagraph (ii), a            fine of $35.                (ii)  For a violation of subsection (b), a fine of            not more than $500 if the person exceeds the maximum            speed limit by more than 11 miles per hour.            (2)  Any person exceeding a maximum speed limit        established under this section by more than five miles per        hour shall pay an additional fine of $2 per mile for each        mile in excess of five miles per hour in excess of the        maximum speed limit.
