CHAPTER VI--FEDERAL TRANSIT ADMINISTRATION, DEPARTMENT OF TRANSPORTATION
 
PART 655_PREVENTION OF ALCOHOL MISUSE AND PROHIBITED DRUG USE IN TRANSIT OPERATIONS--Table of Contents
 
                       Subpart E_Types of Testing
 
Sec.  655.45  Random testing.

    (a) Except as provided in paragraphs (b) through (d) of this 
section, the minimum annual percentage rate for random drug testing 
shall be 50 percent of covered employees; the random alcohol testing 
rate shall be 10 percent. As provided in paragraph (b) of this section, 
this rate is subject to annual review by the Administrator.
    (b) The Administrator's decision to increase or decrease the minimum 
annual percentage rate for random drug and alcohol testing is based, 
respectively, on the reported positive drug and alcohol violation rates 
for the entire industry. All information used for this determination is 
drawn from the drug and alcohol Management Information System (MIS) 
reports required by this part. In order to ensure reliability of the 
data, the Administrator shall consider the quality and completeness of 
the reported data, may obtain additional information or reports from 
employers, and may make appropriate modifications in calculating the 
industry's verified positive results and violation rates. Each year, the 
Administrator will publish in the Federal Register the minimum annual 
percentage rates for random drug and alcohol testing of covered 
employees. The new minimum annual percentage rate for random drug and 
alcohol testing will be applicable starting January 1 of the calendar 
year following publication.
    (c) Rates for drug testing. (1) When the minimum annual percentage 
rate for random drug testing is 50 percent, the Administrator may lower 
this rate to 25 percent of all covered employees if the Administrator 
determines that the data received under the reporting requirements of 
Sec.  655.72 for the two preceding consecutive calendar years indicate 
that the reported positive rate is less than 1.0 percent.
    (2) When the minimum annual percentage rate for random drug testing 
is 25 percent, and the data received under the reporting requirements of 
Sec.  655.72 for the calendar year indicate that the reported positive 
rate is equal to or greater than 1.0 percent, the Administrator will 
increase the minimum annual percentage rate for random drug or random 
alcohol testing to 50 percent of all covered employees.
    (d) Rates for alcohol testing. (1)(i) When the minimum annual 
percentage rate for random alcohol testing is 25 percent or more, the 
Administrator may lower this rate to 10 percent of all covered employees 
if the Administrator determines that the data received under the 
reporting requirements of Sec.  655.72 for two consecutive calendar 
years indicate that the violation rate is less than 0.5 percent.
    (ii) When the minimum annual percentage rate for random alcohol 
testing is 50 percent, the Administrator may lower this rate to 25 
percent of all

covered employees if the Administrator determines that the data received 
under the reporting requirements of Sec.  655.72 for two consecutive 
calendar years indicate that the violation rate is less than 1.0 percent 
but equal to or greater than 0.5 percent.
    (2)(i) When the minimum annual percentage rate for random alcohol 
testing is 10 percent, and the data received under the reporting 
requirements of Sec.  655.72 for that calendar year indicate that the 
violation rate is equal to or greater than 0.5 percent, but less than 
1.0 percent, the Administrator will increase the minimum annual 
percentage rate for random alcohol testing to 25 percent of all covered 
employees.
    (ii) When the minimum annual percentage rate for random alcohol 
testing is 25 percent or less, and the data received under the reporting 
requirements of Sec.  655.72 for that calendar year indicate that the 
violation rate is equal to or greater than 1.0 percent, the 
Administrator will increase the minimum annual percentage rate for 
random alcohol testing to 50 percent of all covered employees.
    (e) The selection of employees for random drug and alcohol testing 
shall be made by a scientifically valid method, such as a random number 
table or a computer-based random number generator that is matched with 
employees' Social Security numbers, payroll identification numbers, or 
other comparable identifying numbers. Under the selection process used, 
each covered employee shall have an equal chance of being tested each 
time selections are made.
    (f) The employer shall randomly select a sufficient number of 
covered employees for testing during each calendar year to equal an 
annual rate not less than the minimum annual percentage rates for random 
drug and alcohol testing determined by the Administrator. If the 
employer conducts random drug and alcohol testing through a consortium, 
the number of employees to be tested may be calculated for each 
individual employer or may be based on the total number of covered 
employees covered by the consortium who are subject to random drug and 
alcohol testing at the same minimum annual percentage rate under this 
part.
    (g) Each employer shall ensure that random drug and alcohol tests 
conducted under this part are unannounced and unpredictable, and that 
the dates for administering random tests are spread reasonably 
throughout the calendar year. Random testing must be conducted at all 
times of day when safety-sensitive functions are performed.
    (h) Each employer shall require that each covered employee who is 
notified of selection for random drug or random alcohol testing proceed 
to the test site immediately. If the employee is performing a safety-
sensitive function at the time of the notification, the employer shall 
instead ensure that the employee ceases to perform the safety-sensitive 
function and proceeds to the testing site immediately.
    (i) A covered employee shall only be randomly tested for alcohol 
misuse while the employee is performing safety-sensitive functions; just 
before the employee is to perform safety-sensitive functions; or just 
after the employee has ceased performing such functions. A covered 
employee may be randomly tested for prohibited drug use anytime while on 
duty.
    (j) If a given covered employee is subject to random drug and 
alcohol testing under the testing rules of more than one DOT agency for 
the same employer, the employee shall be subject to random drug and 
alcohol testing at the percentage rate established for the calendar year 
by the DOT agency regulating more than 50 percent of the employee's 
function.
    (k) If an employer is required to conduct random drug and alcohol 
testing under the drug and alcohol testing rules of more than one DOT 
agency, the employer may--
    (1) Establish separate pools for random selection, with each pool 
containing the covered employees who are subject to testing at the same 
required rate; or
    (2) Randomly select such employees for testing at the highest 
percentage rate established for the calendar year by any DOT agency to 
which the employer is subject.
