The ignition interlock for drunk driversThe ignition interlock is a high-tech system that evaluates the person's blood alcohol level (blood alcohol content) to see if they drank. The device works like a normal breathalyzer. The device is mounted on the dashboard and for the car to start, the individual must blow into the machine. The machine then assesses the person's blood alcohol level and if that person shows no signs of drinking, the car will start. If the results indicate that alcohol has been consumed, the vehicle will not start. When the vehicle starts and after about an hour, the person must blow into the machine again to assess its condition again. The maximum limit when speaking aloud is 0.04 mg of alcohol per 100 ml of blood. Every time the individual uses the system and the small computer, they record information. The system itself costs around 135.00 with a maintenance fee of around 100.00 per month. The hypotheses of this program are as follows: Is the ignition interlock program effective in reducing impaired driving recidivism? Does this impact more severe and persistent impaired drivers? Finally, does the program continue to be effective even after the locking device is removed? (Weinrath) A random sampling of Canadian drivers whose licenses were suspended between 1989 and 1994 was the subject of the IIP (Ignition Antilock Program). The sample consisted of 994 delinquents aged 20 and over. 125 of them were women, 701 were men and 189 were ignition interlock cases. The distribution was 168 IIP cases and 826 drunk driving offenders for the comparison group. These tests were carried out in Canada and others in the states of Ohio, California and Oregon. The problems with these tests were inaccurate data received from these tests. In Ohio and California, no control groups were used and the data fails to provide them with the correct information. The control group was used in Oregon with two sides, one group was created using reinstated drivers who had never had the program. Using Offenders Who Used IIP Due to the short duration of the experiment, it was difficult to obtain long-term data from the study, which created the other group. Referring to samples taken in Canada. 87% of them were men in their 30s who were employed (75%). 43% of them were married and in a normal relationship. 57% of them were single or divorced or widowed.
