Many people in Philadelphia are charged with DUIs every year. If a person is convicted, the consequences can be very serious, including the loss of their driver's license. After a person's driver's license is suspended, if they want to drive they must use the ignition interlock system in their vehicle for a period of time. The amount of time depends on their BAC at the time of the incident and how many prior DUIs he or she may have at the time.
The ignition interlock system is a device that is installed in the person's vehicle that requires a person to blow into it to determine their BAC level. If the device detects alcohol then the device will not allow the engine of the car to start. It also requires a person to blow into it periodically while the vehicle is running to test the person's BAC.
If a person is required to have ignition interlock in their vehicle, he or she must first apply for a restricted ignition interlock license. The person will also have to list all vehicles that he or she owns or leases. Then the person will have to go to an approved ignition interlock provider to have the device installed in all the vehicles.
If the person convicted of DUI is caught driving a vehicle without the ignition interlock system installed, have tampered with the device or removed it before the time period has expired, they can be charged with additional crimes. In addition to the new offense, the person would also be required to continue with ignition interlock for an additional year.
There are many drivers in Philadelphia who have been convicted of multiple DUIs and have to use the ignition interlock system. This is only meant to provide general information about ignition interlock and is not legal advice. Experienced attorneys may be able to assist one who is facing another DUI charge and may be forced to use the ignition interlock device.
