| Role of Expert Testimony in Drunk Driving Cases |
|
| When an individual has been charged with drunk driving, the State will often present expert testimony concerning chemical tests. The State is required to provide a proper foundation for chemical tests. However, if the defense can show that the State's expert lacked the required qualifications or that another key component of a proper foundation for admissibility is missing, the defense can object to the admission of the chemical tests. Although courts may allow an expert to testify regarding the results of tests done by a lab technician under the expert's direct supervision, the evidence can be excluded if the defense can show that the expert witness had no knowledge about the details of the chemical analysis other than what the technician reported.

| Uses of Detection Devices in Speeding Offenses |
|
| In a prosecution for speeding, the prosecutor has the burden of proving each and every element of the case by competent and credible evidence. Normally, the proof will be obtained by the prosecutor from the testimony of the officer. The basic testimony will convey a visual observation or independent estimate of speed made by the officer, corroborated by a calibrated speedometer reading or calibrated radar unit readout. There are essentially five ways for law enforcement officers to determine speed: (1) pacing the motorist's vehicle with the officer's patrol car; (2) obtaining a time-distance measurement with manually activated time; (3) obtaining a time-distance measurement with automatically activated time distance devices; (4) radar; and (5) laser devices.

| Penalties for Driving at an Excessive Rate of Speed |
|
| While a speeding conviction is generally not considered a serious offense, it may have serious implications. If the speed is considered "excessive," (e.g. 30 to 60 miles over the posted speed limit), the conviction will include a fine, imprisonment, and possible suspension of a driver's license. Other criminal actions related to speeding may include "reckless driving" and "racing." Moving violations are either traffic infractions or criminal misdemeanors, and they may necessitate a court appearance.
