2011 SESSION
11100363DBe it enacted by the General Assembly of Virginia:
1. That § 46.2-878 of the Code of Virginia is amended and reenacted as follows:
§ 46.2-878. Authority to change speed limits.
Notwithstanding the other provisions of this article, the
Commonwealth Transportation Commissioner or other authority having jurisdiction
over highways may decrease the speed limits set forth in § 46.2-870 and may
increase or decrease the speed limits set forth in §§ 46.2-873 through 46.2-875
on any highway under its jurisdiction; and may
establish differentiated speed limits for daytime and nighttime by decreasing
for nighttime driving the speed limits set forth in § 46.2-870 and by
increasing for daytime or decreasing for nighttime the speed limits set forth
in §§ 46.2-873 through 46.2-875 on any highway under his jurisdiction; and may establish
differentiated speed limits
based on traffic conditions, atmospheric conditions, weather, emergencies, and
like conditions that may affect driving safety. Such
increased or decreased speed limits and such differentiated speed limits for daytime
and nighttime driving, traffic
conditions, weather, emergencies, and other conditions that may affect driving
safety shall be effective only when prescribed after a
traffic engineering investigation and when indicated on the highway by signs.
It shall be unlawful to operate any motor vehicle in excess of speed limits
established and posted as provided in this section. The increased or decreased
speed limits over highways under the control of the Commonwealth Transportation
Commissioner shall be effective only when prescribed in writing by the
Transportation Commissioner and kept on file in the Central Office of the
Department of Transportation. Whenever the speed limit on any highway has been
increased or decreased or a differential speed limit has been established and
such speed limit is properly posted, there shall be a rebuttable presumption
that the change in speed was properly established in accordance with the
provisions of this section.
