Amount of use

(6) Amount of use. The amount of truck use is the traveling time as com-

pared to the total operating time. Take the total traveling time and divide it by the

total clock time from the chart, then multiply the answer by 100. This answer will

give you the amount of time the truck was used during the 24-hour period.

Traveling time x 100

Amount of use =

Total time

NOTE

The size of the load will affect the traveling time.

(7) Average speed. Average speed can be figured from chart readings.

Take the miles traveled and divide them by the actual driving time in minutes from

the chart, then multiply the answer by 60.

Miles traveled

Average speed = Actual driving time in minutes x 60

MPH

(8) Legal speed limits. For certain types of trucks, the law limits how fast

they may travel on public roads. Check charts from time to time to make sure these

laws are obeyed.

(9) Distance traveled in miles. The amount of miles the truck has traveled

can be found by the odometer reading and the chart reading. The mileage counter

section of the distance recorder counts all miles traveled, even if the tachograph was

left open. The day's journey or part journey can be read from the chart. At the

start and the end of a journey, distance recorder readings must be written in the

inner field of the chart. The distance traveled will be the reading on the odometer

at the beginning of the journey subtracted from the odometer reading at the end of

the journey. This reading must be the same as the distance recording field on the

chart, unless the readings written on the chart were false or the tachograph was

left open.
