Amend CSSB 370 in Article 1 by adding the following
appropriately numbered sections to read as follows and by
renumbering the remaining sections as appropriate:
      SECTION 1.____.  (a)  Subsection (b), Section 545.352,
Transportation Code, is amended to read as follows:
      (b)  Unless a special hazard exists that requires a slower
speed for compliance with Section 545.351(b), the following speeds
are lawful:
            (1)  30 miles per hour in an urban district on a street
other than an alley and 15 miles per hour in an alley;
            (2)  70 miles per hour in daytime and 65 miles per hour
in nighttime if the vehicle is a passenger car or motorcycle on a
highway numbered by this state or the United States outside an
urban district, including a farm-to-market or ranch-to-market road
if that road has a pavement width greater than 20 feet;
            (3)  60 miles per hour in daytime and 55 miles per hour
in nighttime if the vehicle is a passenger car or motorcycle on a
highway that is :
                  (A)  outside an urban district and not a highway
numbered by this state or the United States; or
                  (B)  a farm-to-market or ranch-to-market road
that has a pavement width of 20 feet or less in rolling terrain as
defined by department rule;
            (4)  60 miles per hour outside an urban district if a
speed limit for the vehicle is not otherwise specified by this
section; or
            (5)  outside an urban district:
                  (A)  45 miles per hour, if the vehicle is towing
a house trailer of an actual or registered gross weight heavier
than 4,500 pounds or larger than 32 feet, excluding the tow bar;
                  (B)  50 miles  per hour if the vehicle is a
school bus; or
                  (C)  60 miles per hour in daytime and 55 miles
per hour in nighttime if the vehicle is a truck, other than a light
truck, or if the vehicle is a truck tractor, trailer, or
semitrailer, or a vehicle towing a trailer, semitrailer, another
motor vehicle or house trailer of an actual or registered gross
weight lighter than 4,500 pounds and length of 32 feet or shorter,
excluding the tow bar.
      (b)  A change in a speed limit made by or under this section
applies only to an offense committed on or after the effective date
of the change. For purposes of this section, an offense was
committed before the effective date of a change in a speed limit if
any element of the offense occurred before that date. An offense
committed before the effective date of a change in a speed limit is
covered by the law in effect when the offense was committed, and
the former law is continued in effect for that purpose.
      SECTION 1.____.  Section 545.353, Transportation Code, is
amended by adding Subsection (h) to read as follows:
      (h)  A prima facie speed limit under Section 545.352(b)(3)
may be increased if the commission determines from the results of
an engineering and traffic investigation that a higher prima facie
speed limit is reasonable and safe.
