CHAPTER 41. RULES OF THE ROAD


Subchapter VIII. Speed Restrictions


§ 4168. General speed restrictions.


(a) No person shall drive a vehicle on a highway at a speed greater than is reasonable and prudent under the conditions and
without having regard to the actual and potential hazards then existing. In every event, speed shall be so controlled as may
be necessary to avoid colliding with any person, vehicle or other conveyance on or entering the highway, in compliance with
legal requirements and the duty of all persons to use due care.


(b) The driver of every vehicle shall, consistent with the requirements of subsection (a) of this section, drive at an appropriate
speed when approaching and crossing an intersection or railway grade crossing, when approaching and going around a curve,
when approaching a hill crest, when traveling upon any narrow or winding roadway and when a special hazard exists with respect
to pedestrians or other traffic or by reason of weather or highway conditions.

§ 4169. Specific speed limits; penalty.


(a) Where no special hazard exists, the following speeds shall be lawful, but any speed in excess of such limits shall be
absolute evidence that the speed is not reasonable or prudent and that it is unlawful:


All types of vehicles:


(1) 25 miles per hour in any business district;


(2) 25 miles per hour in any residential district;


(3) 20 miles per hour at all school zones where 20 mph regulatory signs are posted and state the time periods or conditions
during which the speed limit is in effect; such conditions may include when children are present or while 1 or more warning
lights flash;


(4) 50 miles per hour on 2-lane roadways;


(5) 55 miles per hour on 4-lane roadways and on divided roadways.


(b) Whenever the Department of Transportation shall determine, on the basis of engineering studies and traffic investigations
or upon the basis of a federal law or directive by the Congress or the President, that a maximum speed limit set pursuant
to subsection (a) of this section in any particular place on the state maintained highway system is greater or less than is
reasonable or safe, the Department shall declare a reasonable and safe maximum limit thereat, which limit shall be effective
when posted. Such maximum limit may be declared to be effective either part or all of the time and differing limits may be
established for different times of the day, for different types of vehicles, for different weather conditions and when other
significant factors differ. Such maximum limits may be posted on fixed or variable signs. Any speed in excess of such displayed
limits shall be absolute evidence that the speed is not reasonable or prudent and that it is unlawful.


(c) Penalties for violation of this section are as follows:


(1) Whoever violates this section shall for the first offense be fined $20. For each subsequent offense, the person shall
be fined $25 or be imprisoned not less than 10 nor more than 30 days, or both. A subsequent violation, before being punishable
as such, shall have been committed within 24 months after the commission of the prior offense.


(2) Any person violating this section who exceeds the maximum speed limit by more than 5 miles per hour but less than 16 miles
per hour shall pay an additional fine of $1 per mile, if such violation is a first offense, or $2 per mile, if such violation
is a subsequent offense, for each mile in excess of the maximum speed limit.


(3) Any person violating this section who exceeds the maximum speed limit by more than 15 miles per hour but less than 20
miles per hour shall pay an additional fine of $2 per mile, if such violation is a first offense, or $3 per mile, if such
violation is a subsequent offense, for each mile in excess of the maximum speed limit.


(4) Any person violating this section who exceeds the maximum speed limit by more than 19 miles per hour shall pay an additional
fine of $3 per mile, if such violation is a first offense, or $4 per mile, if such violation is a second offense, for each
mile in excess of the maximum speed limit.


(d) The Department of Transportation shall designate a maximum speed limit of 65 miles per hour for all portions of Delaware
State Route 1 located between the Red Lion Creek and the Appoquinimink River. Such maximum limits may be posted on fixed or
variable signs. Any speed in excess of such displayed limits shall be absolute evidence that the speed is not reasonable or
prudent and that it is unlawful.

(a) Whenever local authorities within their respective jurisdictions determine upon the basis of an engineering and traffic
investigation that the absolute speed permitted under this chapter is greater than is reasonable or safe under the conditions
found to exist, such local authority, subject to subsection (c) of this section, shall determine and declare a reasonable
and safe absolute speed limit, which shall be effective when appropriate signs giving notice thereof are erected.


(b) Local authorities in their respective jurisdictions may at their discretion, but subject to subsection (c) of this section,
authorize by ordinance higher absolute speeds than those stated in this chapter upon through highways or upon highways or
portions thereof where there are no intersections or between widely spaced intersections provided signs are erected giving
notice of the authorized speed, but local authorities shall not modify or alter the basic rule set forth in subsection (a)
of § 4168 of this title.
