§ 1128. Driving on roadways laned for traffic. Whenever any roadway has been divided into two or more clearly marked lanes for traffic the following rules in addition to all others consistent herewith shall apply: (a) A vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety.Read the full section at the New York State SenateIn everyday language
The supplied provision requires staying within one clearly marked lane as nearly as practicable and checking that a movement out of the lane can be made safely before moving. The prosecutor must prove the charged failure beyond a reasonable doubt, accounting for the roadway and practicability requirements.
At a criminal trial, the prosecutor must prove every element of the charged subsection and that you committed the offense beyond a reasonable doubt. An accusation is not proof of guilt. Where the statute provides alternatives, the prosecutor need not prove every alternative; the charged theory matters. Affirmative defenses may have different proof rules.
CPL § 70.20What the prosecutor must prove
- The roadway had two or more clearly marked traffic lanes.
- The person accused drove the vehicle and either failed to keep it entirely within one lane as nearly as practicable or moved from the lane without first ascertaining that the movement could be made safely.
- These are alternative ways to violate the supplied duties, not cumulative requirements for an allegation; the prosecutor must prove the applicable violation beyond a reasonable doubt.
Defenses that commonly apply
- Were two or more traffic lanes clearly marked at the location?
- Did roadway conditions make remaining entirely within one lane impracticable?
- What observations or actions show whether the person accused first checked that the lane movement could be made safely?
Penalties and collateral consequences
A Traffic infraction carries a maximum sentence of no jail and a fine of up to $150 for a first offense, plus a surcharge.
Common questions about your defense
Can road conditions matter when contesting an alleged lane departure?
The lane-keeping duty expressly applies as nearly as practicable. Conditions making full lane compliance impracticable could therefore matter, but the separate duty to ascertain safety before moving from the lane remains relevant. The prosecutor must prove the applicable violation beyond a reasonable doubt.
Why is starting a defense early imperative?
An early defense is imperative to protect your rights and preserve evidence that may disappear. Keep court papers, messages, footage, and witness information without deleting or altering anything. Counsel can review court dates and applicable deadlines, request evidence, and begin preparing your defense immediately.
How does an experienced lawyer help build the best possible defense?
Your lawyer checks the exact subsection, compares its requirements with the evidence, and listens to your account. Depending on the charge, counsel may investigate identification, intent, witness reliability, and possible problems with searches, statements, or testing. Working together on an early strategy is imperative to pursue the best possible outcome in your circumstances; no outcome is guaranteed.
Does an arrest or police report prove the charge?
No. A police report is part of the case, not a finding of guilt. Your lawyer can compare its claims with video, records, and witnesses and assess whether admissible evidence meets each applicable requirement.
Can the charge be dismissed or reduced?
That depends on the evidence, the charged subsection, and procedural rules. Challenging evidence, filing motions, negotiating a legally available resolution, or preparing for trial may be appropriate. No lawyer can promise dismissal, reduction, or acquittal.
