| Warrantless Inventory Searches of Impounded Vehicles |

| 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.

| Ignition Interlock Devices in DUI Cases |
|
| State legislatures have addressed the public safety problem of recidivist drunk drivers by authorizing various types of law enforcement tools. One such tool is the "ignition interlock" device, which attaches to the vehicle's steering mechanism and ignition. When used by the courts or state motor vehicle departments in conjunction with a monitoring, reporting, and support program, the ignition interlock system provides drunk driving offenders (driving while intoxicated (DWI) or driving under the influence (DUI)) with an alternative to full license suspension.
