Trooper Marc Griggs Hits First-Ever Milestone

DES MOINES, Iowa -- Today, July 2, 2015, Iowa State Patrol Trooper Marc Griggs was recognized for hitting a major milestone in the fight against drugged driving in Iowa.

Griggs, one of 125 certified Drug Recognition Experts (DRE) in Iowa, recently completed his 500th Drug Recognition Expert evaluation—the first ever to accomplish this in Iowa. Griggs has been a certified DRE since 2001 and is a 22 year veteran of the Iowa State Patrol.

“His commitment and dedication to keeping motorists safe is certainly worthy of special recognition and we are pleased to be able to recognize his efforts,” said GTSB Bureau Chief Patrick Hoye.

The DRE program is sponsored by the Iowa Department of Public Safety’s (DPS) Iowa Governor’s Traffic Safety Bureau (GTSB). The GTSB works closely with many law enforcement agencies (police departments, sheriff’s offices and the Iowa State Patrol) across Iowa with the ultimate goal of reducing fatality serious injury crashes.

The latest trends show that impaired driving is not just drunk driving in the U.S. Impaired drivers are under the influence of illegal and sometimes even legal drugs that pose just as much of a threat to motorists as drunk drivers.

In Iowa, approximately 30% of fatalities are impaired driving related. One of the issues for law enforcement is determining impairment for a driver that is under the influence of drugs. The indicators for impairment are different for alcohol and certain drugs. That is where the DRE’s and the DRE program has had a positive impact. Officers receive specialized training that allows them to asses a driver’s condition and then take appropriate action.
