Summary of State Speed Laws
 
 

INTRODUCTION

PURPOSE

This Summary reports ONLY the status of State statutes (or regulations) that are concerned with either speed limit or speed related violations. Local laws are not reported. Unless otherwise indicated, the status of the State laws (or regulations) reported is January 1, 1997.

ORGANIZATION

The Summary is divided into three areas: (1) Introduction; (2) Summary Tables; and, (3) a State by State Analysis. The State by State Analysis is organized by State and then by specific legal topics. The State by State Analysis includes code and, where needed, case law citations; these should help individuals conducting additional research in this area of the law. The State by State Analysis can be used to facilitate the comparison of State laws in the subject areas.

The Appendix, using the State by State Analysis' format, gives the Uniform Vehicle Code's provisions on speed limit and speed related offenses.

EXPLANATIONS

Basic Speed Rule. The Basic Speed Rule requires vehicle operators to drive at a speed that is reasonable and prudent. As a corollary to this rule, State laws usually provide that "every person shall drive at a safe and appropriate speed when approaching and crossing an intersection or railroad grade crossing, when approaching an going around a curve, when approaching a hill crest, when traveling upon any narrow or winding roadway, and when special hazards exist with respect to pedestrians or other traffic or by reason of weather or highway conditions." See Uniform Vehicle Code §11-801.

Minimum Speed Rule. The Minimum Speed Rule prohibits a person from operating a motor vehicle at such a slow speed as to impede the normal and reasonable movement of traffic. However, in order to avoid a possible conflict with the basic speed rule, the law normally provides that a slow speed is permissible when "reduced speed is necessary for safe operation or in compliance with law." See Uniform Vehicle Code §11-805(a).

Racing on the Highway. The offense of "racing on the highway" is usually defined as driving "any vehicle in any race, speed competition or contest, drag race or acceleration contest, test of physical endurance, exhibition of speed or acceleration, or for the purpose of making a speed record." See Uniform Vehicle Code §11-809(a).

Drag Racing. Either as part of the offense of highway racing or as a separate statutory crime, the offense of "drag racing" is normally defined as "the operation of two or more vehicles from a point side by side at accelerating speed in competitive attempt to outdistance each other, or the operation of one or more vehicles over a common selected course, from the same point to the same point, for the purpose of comparing the relative speeds or power of acceleration of such vehicles or vehicles within a certain distance or time limit." See Uniform Vehicle Code §11-809(b).

Reckless Driving. The criminal offense of "reckless driving" is defined as driving "any vehicle in willful or wanton disregard for the safety of persons or property." See Uniform Vehicle Code §11-901(a). Note: Speed is not necessarily a factor in this offense.

Statutory Speed Limit. In the State by State analysis, this category identifies State laws that provide for maximum speed limits. Such limits may vary by highway type (e.g., interstate) or by location (e.g., urban district). Some State laws require that these limits be posted. However, in other States, the law provides that these limits apply in the absence of a posted speed limit.

Posted (Maximum) Speed Limit. In the State by State analysis, this category identifies State laws that allow either State or local authorities to alter (e.g., increase or decrease) the statutory speed limits. However, these provisions usually require that, prior to increasing or decreasing a highway's statutory speed limit, the appropriate governmental authorities conduct a study to determine the safe speed limit for such highway. State law may also allow authorities to specify different speed limits either for various times of the day or for various types of vehicles (e.g., trucks). Speed limits established under these laws are not effective until appropriate speed limit signs are posted on the highway. Caution: This Summary does not report the speed limits that have been established via such laws.

Speed Law Sanctions. Except as noted, the criminal and administrative (licensing) sanctions given are the same for any offense listed under the heading "Basis for a Speed Violation." Important: The fine sanctions listed in this Summary do not include court costs or bail schedule forfeitures.

Highway. As used in most State motor vehicle laws, "highway" is defined as "[t]he entire width between the boundary lines of every way publicly maintained when any part thereof is open to the use of the public for purposes of vehicular travel." "Highway" and "street" are synonymous and interchangeable terms. See Uniform Vehicle Code §1-127 Note: As defined, a "highway" under most State laws means only a government owned or maintained street and not a "private" one.
