In a DWI arrest the police will need to use a method to test the Blood Alcohol Content (BAC) of a driver’s blood to determine if the driver is intoxicated or impaired after consuming alcohol.  The most common method is to have the motorist blow into a machine to test the alcohol level in the motorist blood.  The machine looks like a large computer and has a keypad in the front.  After blowing into a tube for a few seconds the machine will test the motorist’s breath and submit a result to the police.   The machine’s calibration in any DWI test must be investigated and attacked.

Proof of Breathalyzer Calibration

In New York State the proof necessary by the prosecution in a DWI case is that the Breathalyzer was in proper working order at the time the test was administered to the motorist.  The prosecution has this burden at trial and must prove this element beyond a reasonable doubt.  The prosecution typically introduce into evidence a document entitled “record of calibration/maintenance.”  This is also called the certificate of calibration of the Breathalyzer.

What is a Calibration?

In the field of DWI defense “calibration” refers to the inspection, calibration and repair of the breath test devices by specially trained technicians at facilities such as the New York State Police Crime Laboratory or the New York State Division of Criminal Justice Services Office of Public Safety.  This calibration is NOT the weekly test conducted by the police officers at the police station.  This is a much more complex test for calibration.

Suppression of a Breath Test due to Calibration

In People v Todd, 79 Misc.2d 630, a breathalyzer had not been calibrated for six months and the People failed to establish that the breathalyzer apparatus had been timely calibrated hence the results of the test were inadmissible.  It is incumbent upon the District Attorney to show that the machine was in proper working order.

Todd Six Month Calibration Rule

Although lower courts have expanded the six month rule with respect to the calibration of a Breathalyzer the Court of Appeals has never reversed or altered its six month rule.  This is something that the best criminal defense DWI lawyers must investigate when defending a DWI arrest.

New Breathalyzer Machines

The New York State Police have chosen to calibrate their newest breath test device, the Draeger AlcoTest 7110 MK III (Draeger) only one a year.  Regardless the prosecution must lay a sufficient foundation as to the reliability of the Draeger.  The Todd rule should apply and the government can present expert witnesses to prove calibration.

A common mistake is to look at a traffic ticket in New York and think, all is lost, there can be no possible defense.  Usually there are several defenses to a traffic ticket and as any good criminal defense attorney will tell you it all starts with the traffic ticket itself.

In New York State traffic tickets are written for any crime or violation under the New York State Vehicle and Traffic Law (VTL).  Tickets can be written for moving violations such as speeding, non-moving violations, equipment violations even DWI and DWAI Drugs.  The traffic ticket is the basis for a prosecution and it the starting point for the defense to the charge.

1. The Ticket (Simplified Traffic Information)   

The Ticket is usually a half page document, yellow in color, that a police officer would hand you on the side of the road.  A State Trooper may provide you with a full page ticket (white in color) but usually its the front and the back of the “yellow” ticket on one page.  The front of the ticket outlines the charge while the back has instructions regarding how to respond.  The ticket is also known as a Simplified Traffic Information.

The sufficiency of a simplified traffic information is governed by the criminal procedure law.  Because the traffic ticket is the local court accusatory instrument that provides the least amount of information. the recipient is entitled as a matter of right, upon a timely request, to a supporting deposition.

2. The Supporting Deposition

The supporting deposition is a document that explains the charge in greater detail.  The supporting deposition must be completed by the police officer and must allege all of the elements of the offense.  The statute provides that the allegations may be made upon personal knowledge or upon information and belief providing reasonable cause to believe that the driver committed the offense charged. 

3. Probable Cause

The ticket and supporting deposition together must provide probable cause to believe that the traffic offense in questions was committed.  A supporting deposition that contains boxes checked off by the police officer is sufficient.

4. Time to request a Supporting Deposition from the Police

In some cases a driver will receive a supporting deposition from the police with the traffic ticket, usually issued by the State Police, but in most instances the police officer will only provide a traffic ticket without a supporting deposition.

The request a supporting deposition must be made within 30 days of the court appearance noted on the ticket.  Where the charge is a misdemeanor such as DWI or reckless driving the driver may request a deposition beyond the 30 day period up to 90 days with permission of the court.

5.  The Plea 

Always plea NOT GUILTY to a traffic ticket.  In most cases an experienced criminal defense lawyer can get the charge dismissed or reduced.  A guilty plea is the same as if you went to trial and were found guilty by the judge or jury.  Your best option is to contact one of our experienced criminal defense lawyers to aggressively attack the ticket and its contents even before appearing in Court.

A plea can be entered in court on the date at the bottom of the ticket or by a signed statement on the ticket by mail.  When pleading not guilty by mail, the plea must be sent by registered or certified or first-class mail and within 48 hours of receiving the ticket .  A driver may plea not guilty by mail and request a supporting deposition.  FAILURE to act in a timely matter will cause a loss of the right to the supporting deposition.

6.  Service of the Supporting Deposition

The deposition must be provided to the driver within 30 days of the court’s receipt of the request for it OR 5 days before trial whichever comes first.

7.  Failure to provide a Supporting Deposition

When the court orders the filing of a supporting deposition and the police officer fails to comply in a timely manner the ticket is rendered insufficient on its face and may result in a dismissal. 

The above is one of the basic and best defenses to traffic tickets.  Although there are many defenses this requirment always remains at the core.  It is important to have a traffic ticket attorney since the police officer may try to submit a late supporting deposition or other method to prevent the case from being dismissed.  Our traffic ticket attorneys are prepared to protect your rights and provide you with the best possible criminal defense either in a traffic ticket case, DWI case or other criminal matter.
