The appropriate number of drug and alcohol tests: Answers
Answers:
First quarter: 8 for drug testing and 2 for alcohol testing.
| When testing quarterly and you have 60 drivers for the selection period, this is how the calculations work: Drugs: .50 x 60 / 4 = 7.5 tests rounded up to 8. Alcohol: .10 x 60 / 4 = 1.5 rounded up to 2 |
Second quarter: 10 for drug testing and 2 for alcohol.
Third quarter: 13 for drug testing and 3 for alcohol testing.
Fourth quarter: 7 for drugs and 1 for alcohol
It must add together the driver counts for a yearly average: For instance, D = 60 80 100 70 = 310 CMV drivers, and by completing the formula, T = 50% times 310 divided by 4 = 38.75 and rounding up to the nearest whole number, 39 drug tests for the year. For alcohol tests (T = 10% times 310 divided by 4 = 7.75) and rounding up to the nearest whole number, your answer would be 8 for the year.
If all the tests were completed from the previously testing cycles, you should have: 31 tests completed for drugs, requiring a selection of 8 names to be compliant; and 7 tests for alcohol, requiring just 1 name for alcohol.
However, if you had any missed tests (drivers furloughed, on leave of absence, or canceled tests) from earlier in the year, this is the time to compensate and select additional names. Carriers may wish to select a few extra names as policy since the year is almost over, leaving minimal time for a supplemental draw in the event any of the 7 drivers for drug testing and/or the 1 driver for alcohol testing are unavailable or a test is canceled beyond the control of the driver and carrier.
