QUESTION OF FACT WHETHER PLAINTIFF’S LANE CHANGE CONSTITUTED A NON-NEGLIGENT EXPLANATION FOR THIS REAR-END COLLISION, PLEA TO FOLLOWING TOO CLOSELY IS NEGLIGENCE PER SE ONLY IF THE VIOLATION IS UNEXCUSED.

The Fourth Department, reversing Supreme Court, determined plaintiff’s motion for summary judgment in this rear-end collision case should not have been granted. Defendant raised a question of fact whether the cause of the accident was plaintiff’s sudden lane change. The fact that defendant pled guilty to a traffic violation, following too closely, would constitute negligence per se only if unexcused:

Plaintiff … submitted the deposition testimony of defendant, who stated that he did not see plaintiff’s vehicle until immediately before the accident, when plaintiff moved from the middle lane to the right lane and slammed on his brakes in an instant or quickly, i.e., plaintiff’s action was not a slow and cautious movement to which defendant could react … . Defendant explained that he had not seen plaintiff’s vehicle before the collision because he had been paying attention to the road in front of him and, when plaintiff engaged in his maneuver (changed lanes), defendant slammed on his brakes and tried to steer into the shoulder to avoid the accident, which caused the back end of the trailer that was attached to the truck to swing out, and the left corner of the truck struck plaintiff’s vehicle. Based on the foregoing, we conclude that plaintiff “failed to meet his initial burden of establishing his entitlement to judgment as a matter of law inasmuch as he submitted the deposition testimony in which [defendant] provided a nonnegligent explanation for the collision,” namely, that plaintiff caused the collision when he suddenly changed lanes in response to slowing traffic in the middle and left lanes of the highway and abruptly stopped in the right lane in front of defendant … .

… [W]e reject plaintiff’s contention that he established defendant’s negligence as a matter of law by submitting evidence of defendant’s guilty plea of following too closely (Vehicle and Traffic Law § 1129 [a]). “It is well settled that the fact that [the] driver entered a plea of guilty to a Vehicle and Traffic Law offense is only some evidence of negligence and does not establish his negligence per se’ ” … . “Rather, it is the unexcused violation of the Vehicle and Traffic Law [that] constitutes negligence per se’ ” … . Here, upon defendant’s explanation, the trier of fact could excuse the violation on the ground that plaintiff cut in front of defendant and immediately stopped, thereby failing to provide defendant with adequate time to create the “reasonable and prudent” distance between the vehicles that is required by the statute … . Gardner v Chester, 2017 NY Slip Op 05336, 4th Dept 6-30-17
