We can help!

The Offices Of Perry J Zucker, Degreed Engineers, is a widely respected and accomplished forensic engineering firm, operating since 1993. We have a team of knowledgeable professionals, including in-house engineers, technicians, and support staff, who specialize in addressing issues related to police gap time, VASCAR speeding tickets, and traffic violations for probable cause and reasonable suspicion traffic stops.


Role and Responsibility of the Expert Witness - Engineer

An engineer expert witness (EEW) is an individual with specialized knowledge in engineering who aids the judicial system (including judges, juries, and lawyers) in comprehending the technical elements of a case. They may be called upon to clarify the application of scientific principles as well as the operation of the device in relation to specific scenarios, particularly within the context of laws and regulations. The EEW may provide testimony regarding the accuracy of police gap time / VASCAR measuring devices, the geographical features of a specific roadway, and the correct usage of such devices. It is essential to note that all our conclusions are based on evidence-backed data, not mere speculation, or untrustworthy pseudo-science.


Robic / Gap Time / Vascar Speeding - How Police Gap Time / Vascar Works?

Gap Time, Robust, and Vascar are speed measuring devices commonly used for enforcing speed limits through the Timing, Gap Time, and Vascar methods. These methods involve calculating the average speed between two known points, such as designated markers on the road. To put it simply, the following formulas are employed: (i) d d = d2 - d1, where d represents distance; (ii) d t = t2 - t1, where t represents time; (iii) v = d d/d t, where v denotes velocity. The officer or trooper carefully observes the target vehicle (in this case, the defendant's vehicle) and activates or deactivates the device accordingly. The officer then reads the digital speed display on the gap time, Vascar, or Robic device. Watch the video >


Gap Time / Timing / Vascar / Robic - Standard Operating Procedure

The police officer or operator conducts a series of examinations that may aid in ascertaining the functionality of the gap time or Vascar unit. It is imperative that the police officer or operator receive proper training.


Timing / Robic / Vascar - Distance Between The Points

The distances between two points can vary by more than 50 feet.


Robic / Gap Time / Vascar Speed Accuracy

The use of Gap timing, Vascar, and Robic speeding devices has not received judicial recognition in all states. The ideal level of accuracy specification(s) should be within a decimal point of miles per hour.


Gap Time / Vascar / Robic Errors

In order to maintain accuracy, it is crucial for the police officer to operate the gap time / vascar / robic accurately, while also maintaining the device in optimal working order. Neglecting this responsibility could lead to discrepancies.


Timing / Robic / Vascar Speeding Ticket - Trial Preparation

Review all relevant documents and data. Police Officers who issue gap timing, Vascar speeding tickets, or violations have extensive knowledge and experience in operating the mentioned devices. It is advisable to secure the services of an expert or expert witness with specific expertise in this field. Ideally, the expert should be an engineer who is well-versed in gap time calculations, Vascar and Robic speed measuring devices, certified as a speed measuring device operator and instructor, knowledgeable in police training, vehicle characteristics, certified as a vehicle technician or mechanic, and well-versed in court rules. It is important to note that trial by declaration (mail) is rarely successful, particularly in selected states.
