Test Results vs Time of Offense a Hot Issue for Broward County DUI Lawyers:
Since a person's blood-alcohol level rises over time as alcohol is gradually absorbed into the system, it is possible that the blood-alcohol level was within legal limits at the time a (DUI) defendant actually operated the vehicle and did not exceed such limits until the administration of a breath or blood test, particularly where alcohol was consumed shortly before or while driving.

DUI Lawyers have argued this for years according to William Moore. For more information visit the Fort Lauderdale DUI home page.
Nevertheless, if the test is conducted within a reasonable time after the defendant is stopped, its results are admissible in evidence without "retrograde extrapolation," that is, the presentation of supplementary proof relating the test result back to the time the defendant was operating the vehicle.
An example of this would be a blood-alcohol test conducted in a "reasonable manner," approximately four hours after the defendant's driving which showed a result of 0.08 percent, since the driver's blood-alcohol level should already have peaked and been no higher than it was at the time of driving. Matters of delay between driving and testing, as well as the State's failure to relate the test results back to the time of the offense, go to the credibility and weight of the results, rather than to their admissibility. This is routinely argued by experienced Broward County DUI Lawyers.
For the purpose of determining the admissibility of blood-alcohol evidence, a test is conducted at an unreasonable time if the test results do not tend to prove or disprove a material fact, or if the probative value of the evidence is outweighed by its potential to cause prejudice or confusion.
