Even when drivers are not required by a mandated program to install an ignition interlock device, many responsible drivers enroll in the program on their own. Some of the reasoning might be monetary. A first time DUI offense can easily mount up to $13,000 and a second offense costs even more. Add that to possible jail time, loss of driver’s license and a bad driving record, and it makes sense to take advantage of ignition interlock services. In the same way that parents spend money on child car seats, seat belts and air bag protection, they are also willing to invest in this one item that can save lives. By limiting driving to tested drivers, everyone is safer.
