People v. Mancuso, 14 N.Y.2d 181 (1964)
A statute prohibiting driving at a speed greater than is reasonable and prudent under the conditions, having regard to actual and potential hazards, is constitutional because it incorporates a standard of ordinary negligence that provides sufficient guidance.
Summary
Mancuso was convicted of violating Vehicle and Traffic Law § 1180(a) for driving at an unreasonable speed given existing conditions. He challenged the law’s constitutionality, arguing it was too vague. The Court of Appeals affirmed the conviction, holding that the statute was constitutional because it defined unreasonable speed by reference to what a reasonably prudent person would do under similar circumstances. The court distinguished this statute from prior versions deemed unconstitutional and emphasized that repeated instances of dangerous driving under known hazardous conditions supported the conviction.
Facts
Mancuso was driving on an icy street. He repeatedly attempted to start his car, causing it to spin and slide off the road into a snowbank on three separate occasions. Mancuso was aware of the slippery conditions of the street.
Procedural History
Mancuso was convicted for violating Vehicle and Traffic Law § 1180(a). He appealed, challenging the constitutionality of the statute. The New York Court of Appeals reviewed the case.
Issue(s)
- Whether Vehicle and Traffic Law § 1180(a), prohibiting driving at a speed greater than is reasonable and prudent under the conditions, is unconstitutionally vague.
- Whether the evidence presented was sufficient to convict Mancuso of violating Vehicle and Traffic Law § 1180(a).
Holding
- No, because the statute incorporates a standard of ordinary negligence, providing sufficient guidance for drivers and courts.
- Yes, because the evidence showed that Mancuso repeatedly drove in a manner that was unreasonable and imprudent given the known icy conditions.
Court’s Reasoning
The court reasoned that § 1180(a) does not require a driver to be aware of unforeseen conditions but rather holds them responsible if they are negligent with respect to speed, considering reasonably anticipated hazards. The court distinguished this statute from the reckless driving statute (§ 1190), which requires intentional or abandoned disregard for safety. The court noted that similar statutes in other states have generally been upheld.
The court emphasized that the statute is designed for situations where the legislature considered that the maximum speed should be less than the speeds prescribed in miles per hour, in order to limit the operation of motor vehicles under unusual circumstances. The court favorably cited People v. Grogan, 260 N.Y. 138, noting that a statute prohibiting conduct that “unreasonably interferes” with the highways would be constitutional because it refers to “the failure to exercise reasonable care, reasonable caution or the reasonable foresight of a reasonably prudent and careful person.”
Regarding the sufficiency of the evidence, the court acknowledged that skidding alone is not evidence of negligence. However, it found that Mancuso’s repeated actions, with knowledge of the icy conditions, demonstrated that he was driving at a speed greater than was reasonable and prudent under the circumstances.
The court stated, “This was sufficient to convict him of driving at a speed greater than is reasonable and prudent under the circumstances in violation of subdivision (a) of section 1180 of the Vehicle and Traffic Law.”
