Instruction 5.240, Criminal Model Jury Instructions for Use in the District Court
Operating negligently so as to endanger (G.L. c. 90, § 24 [2][a])
OPERATING NEGLIGENTLY SO AS TO ENDANGER
G.L. c. 90, § 24(2)(a)
The defendant is charged with operating a motor vehicle
negligently in a manner that might endanger the public.
To prove the defendant guilty of this offense, the
Commonwealth must prove three things beyond a reasonable doubt:
First: That the defendant operated a motor vehicle;
Second: That the defendant did so (on a way) (or) (in a place
where the public has a right of access) (or) (in a place where members
of the public have access as invitees or licensees); and
Third: That the defendant did so in a negligent manner so that
the lives or safety of the public might have been endangered.
At this point, the jury must be instructed on the definitions of “Operation of a Motor
Vehicle” (Instruction 3.200) and “Public Way” (Instruction 3.280).
If there is a stipulation to certain elements: [Because the parties have
stipulated (that the defendant was operating a motor vehicle)
(and) (that the location was a public way) (that the location was
one to which the public had a right of access) the only element(s)
the Commonwealth must prove beyond a reasonable doubt (is)
(are) that the defendant list element(s) .]
The third thing the Commonwealth must prove beyond a
reasonable doubt is that the defendant drove negligently in a manner
that might have endangered the lives or safety of other people.
A person acts negligently when they fail to use due care, that is,
when they act in a way that a reasonable person would not act. This
can happen either by doing something that a reasonably prudent
person would not do under those circumstances, or by failing to do
something that a reasonably prudent person would do. The
defendant acted negligently if they drove in a way that a reasonable
person would not have, and by doing so created an unnecessary
danger to other people, a danger that they could have avoided by
driving more carefully.
A. If there was no accident. A person can be found to have
driven negligently even if no accident resulted, and even if
there was no one else actually on the road to be put in
danger. A person is negligent if they drive in a way that
has the potential to cause an accident or to endanger
anyone who might be on the road.
B. If there was an accident. The fact that an accident
occurred is not by itself evidence that the defendant was
negligent. You must examine all the evidence about how
the accident happened in order to determine whether any
negligence was involved, and if so, whether that
negligence was the defendant’s.
In determining whether the defendant drove negligently in a
manner that might have endangered the public, you should take into
account all the facts of the situation: the defendant’s rate of speed
and manner of operation, the defendant’s physical condition and how
well the defendant could see and could control the vehicle, the
condition of the defendant’s vehicle, what kind of a road it was and
who else was on the road, what the time of day, the weather and the
condition of the road were, what any other vehicles or pedestrians
were doing, and any other factors that you think are relevant.
If you find that the defendant acted negligently, the defendant’s
intent is not relevant. You are not required to find that the defendant
intended to act negligently or unlawfully. This is in that category of
situations where public safety requires each driver to determine and
to adhere to an objective standard of reasonable behavior. Therefore,
the defendant’s subjective intent is irrelevant; the issue is whether or
not the defendant drove as a reasonable person would have under the
circumstances.
CONCLUSION
If there are stipulations. Because the parties have stipulated (that
the defendant was operating a motor vehicle) (and) (that the location
was a public way) (that the location was one to which the public had
a right of access), the only element(s) the Commonwealth must
prove beyond a reasonable doubt is (are) that the defendant (state
elements). If the Commonwealth has proved (that) (those) element(s)
beyond a reasonable doubt, you should return a verdict of guilty. If it
has not, you must find the defendant not guilty.
If there are no stipulations. So there are three things that the
Commonwealth must prove beyond a reasonable doubt:
First: That the defendant operated a motor vehicle;
Second: That the defendant did so (on a public way) (or) (in a
place where the public has a right of access) (or) (in a place where
members of the public have access as invitees or licensees); and
Third: That the defendant did so in a negligent manner so that
the lives or safety of the public might have been endangered.
If the Commonwealth has proven all three elements beyond a
reasonable doubt, you should return a verdict of guilty. If the
Commonwealth has failed to prove one or more of these elements
beyond a reasonable doubt, you must return a verdict of not guilty.
See also Instruction 3.180 (Negligence). For a supplemental instruction on violation of the
law as evidence of negligence, see the supplemental instructions to Instruction 3.180. If
the violation is speeding, see the supplemental instructions to Instruction 5.640 (Road
Racing).

relevant factor for jury consideration); Commonwealth v. Campbell, 394 Mass. 77, 83 n.5 &
87 (1985) (speeding not negligence per se but can be considered with other evidence in
determining negligence; victim’s contributory negligence is not defense); Commonwealth
v. Jones, 382 Mass. 387, 389-392 (1981) (negligence to be determined by same standard
as in tort law for purposes of vehicular homicide statute [G.L. c. 90, § 24G], which was taken
almost verbatim from driving so as to endanger statute); Commonwealth v. Charland, 338
Mass. 742, 744 (1959) (speed is relevant factor); Commonwealth v. Gurney, 261 Mass. 309,
312 (1927) (relevant jury factors); Commonwealth v. Vartanian, 251 Mass. 355, 358
(1925) (same); Commonwealth v. Horsfall, 213 Mass. 232, 235 (1913) (reckless operation
can occur even on deserted street); Commonwealth v. Ferreira, 70 Mass. App. Ct. 32
(2007) (conviction supported where defendant backed out of parking space in shopping
center parking lot and then accelerated forward at about 20 m.p.h., causing the wheels to
spin and the back end to fishtail, while the vehicle made a screeching noise);
Commonwealth v. Duffy, 62 Mass. App. Ct. 921, 922 n.2 (2004) (negligence to be
determined by same standard as in tort law; speeding not negligence per se but can be
considered with other evidence in determining negligence); Commonwealth v. Gordon, 15
Mass. App. Ct. 901 (1982), aff’d, 389 Mass. 351 (1983) (negligent inattention to driving
plus glassy eyes and slurred speech will support conviction).
Prior to St. 1928, c. 281, this was a strict liability offense that did not include any
requirement of negligence. That should be kept in mind when reviewing early decisions
involving the former statute.
SUPPLEMENTAL INSTRUCTIONS
1. Negligence or intoxication of other driver. You have heard
testimony suggesting that the driver of the other vehicle
involved in this matter, [name] , was (negligent) (or)
(intoxicated). It is up to you to decide whether or not to
accept that testimony as accurate.
If you do conclude that the other driver was
(negligent) (or) (intoxicated), then you must determine what
role that driver’s (negligence) (or) (intoxication) played in
this matter.
The other driver’s driving is irrelevant to the
defendant’s guilt or innocence on this charge unless the
other driver was the sole cause of what happened. The
defendant is not excused merely because the other driver
was (negligent) (or) (intoxicated), if the defendant’s
negligence was the direct cause of what happened, and the
other driver’s (negligence) (or) (intoxication) merely
aggravated the result. On the other hand, if the other
driver’s (negligence) (or) (intoxication) was the sole cause
of what happened and the defendant was not negligent,
then the defendant must be found not guilty.
Commonwealth v. Galluzzo, 25 Mass. App. Ct. 568 (1988) (judge must allow evidence of
other driver’s negligence if it would warrant a finding that the sole negligence was that of the
other driver, but careful instructions are required to make clear that contributory negligence
is not a defense). In the rare circumstance where there are multiple direct simultaneous
causes of an accident, the supplemental instruction to Instruction 5.160 [Motor Vehicle
Homicide – (Misdemeanor – Negligence)] may be appropriately adapted.
2. Emergency situation. In determining whether the
defendant’s conduct was negligent, you may consider
whether there was a sudden emergency which required
rapid decision. If there was, you must determine whether
the defendant acted as a reasonable person would under
similar emergency circumstances.
Newman v. Redstone, 354 Mass. 379, 383 (1968).
