The Dickson County Sheriff’s Office has gotten the federal approval it needed to use grant funds to purchase a mobile DUI simulator, but now has to negotiate the cost down. Motorcycle officer Paul Montgomery, who heads up the road safety awareness program for the sheriff’s office, said the National Highway Transportation Safety Administration has officially approved the purchase of a DUI simulator that will be used as part of the safety campaign. The sheriff’s office received a $23,000 grant from the Governor’s Highway Safety Office last year, but because the funds are federal, their use required NHTSA approval. The sheriff’s office requested bids for a mobile DUI simulator that can be taken to area schools and other events. Two bids were received by the deadline but one did not meet the specifications for a mobile unit. Accounts and Budget Director Don Hall told county commissioners earlier this month that the one bid that met specs came in about $2,500 over the grant funds, which are for a 100 percent reimbursement. Hall said the county would negotiate with the vendor to try to get the purchase price to within the grant funds and hoped to bring a purchase agreement back at the commission’s April meeting. The DUI simulator will use virtual reality technology to give the driver a sense of what it is like to drive with delayed responses caused by impairment due to alcohol consumption.
