based on the data memory recordings related to the current period where no card was
inserted and related to the relevant slot. For more details see tachograph regulation.
This way of computing the continuous driving time and the cumulative break time serves
into the recording equipment for computing the continuous driving time warning. It does
not prejudge the legal interpretation to be made of these times.
Unknown periods correspond to periods where the driver card was not inserted in a
recording equipment and for which no manual entry of driver activities was made.
D2TRS
Driver2 Time Related States
Driver 2 Time Related States shall be used to indicate if driver 1 approaches/exceeds
working time limits, (or other limits), and provide:
LSB 0000 - no time related warning detected
LSB 0001 - limit #1 : 15 minutes before 4 1/2 h
LSB 0010 - limit #2 : 4 1/2 h reached (continuous driving time
exceeded)
LSB 0011 - limit #3 : 15 minutes before optional warning 1
LSB 0100 - limit #4 : optional warning 1 reached
LSB 0101 - limit #5 : 15 min before optional warning 2
LSB 0110 - limit #6 : optional warning 2 reached
LSB 0111-1100 – reserved
LSB 1101 – other
NOTE:
Only the values 0001 and 0010 are mandatory.
Limit #3 to Limit #6 are optional warnings according to the
tachograph regulation.
If they are implemented, the format is given in this table.

Driver2 Cumulative Break Time
Driver 2 Cumulative Break Time shall be computed from driving time as the current
accumulated availability or break/rest or unknown times of
15 minutes or more of a particular driver, since the end of his last availability or
break/rest or unknown period of 45 minutes or more. This period may have been split in
several periods of 15 minutes or more.
This parameter shall provide:
data length: 2 byte;
resolution:
1 min/bit gain, 0 min offset;
operating range:
0 to 64255;
The computations involved take into account, as needed, past activities stored on the
driver card. Unknown periods of negative duration (start of unknown period > end of
unknown period) due to time overlaps between two different recording equipment, are not
taken into account for the computation.
When the driver has not inserted his card, the computations involved are based on the
data memory recordings related to the current period where no card was inserted and
related to the relevant slot. For more details see Tachograph regulation.
