This research has been done on a sample of 4211 drivers, from which 3886 ( 92,28%) were put in examination for plus measuring alcohol concentration in exhaled air, that is, breath testing with breathalyser type Alcotest® 7410 RS, while 297 of examined people, besides breath testing were put through blood sample analysis, applying ADH enzyme's method. Both sexes were covered in this examination, and they were at the age from 16 to 66, classified according to the clinical phase alcohol taken. Results: Most of the alcoholic drivers were men. The greatest number (94,9% from 4211) didn't participate in a traffic accidents (TA), 3,8% were participants in TA with material damage, and in 1,2% of cases were TA with injuring some of the participants, while in just 4 cases (0,1%) came to mortal injuring participants. The highest number of police controls were registrated on Saturdays, in Summer months, in time from 00:00 to 03:59 hours. Average age of the examined people were 32,5 years old (SD = 0,871), and the greatest number of the examined in this analysed sample belongs to age group from 21 to 30 (1748, that is, 41,51% from 4211). The greatest number of drivers (51,3%) were in clinical phase of mild intoxication. Applying three factor's ANOVA statistical method with one set factor (with part of a day in a month) it is established that arising traffic accidents (TA) depends solely from clinical phase of intoxication. Obtained results taken from breath testing are compared with results received from determinating Blood Alcohol Concentration (BAC) applying enzym's ADH method. Very high coefficient of correlation is established from 0,95 (r 0,198, p>0,0006). In the observed period falling trend of alcoholic drivers is recorded. We can note constant numerical domination of age group of 21 to 30. Driving drunken is typical characteristic for male population. In group of professional drivers it's extremely rare steering a vehicle in alcoholic condition. It is detected that in most cases of TA participants were in mild or medium state of intoxication, what indicates to a major accidental significance precisely these degrees of intoxication
