In 29 states, there are laws that any car moving slower than the surrounding traffic should be in the right lane, while other states are stricter and designate the left lane only for turning or passing. Source: Geico
Why shouldn't you drive slower in the left lane?
When drivers travel in the left lane, it makes the road more congested and probably more dangerous for all parties involved. ... If relatively slow drivers are scattered among the right and left lanes, faster drivers have to repeatedly slow down and weave back and forth, changing lanes many times to pass all of them.
The correct statement is that driving slower in the left lane is a violation of traffic law, as the laws don't permit to drive slower in the left lane. Slower driving can be exercised in the right lane.
The drivers cannot follow the practice of driving slower than the surrounding speed of other cars, as it makes the road dangerous and is punishable with appropriate fines and penalties.
<h3>Traffic Rules. </h3>
As the drivers in the right lane are allowed to drive at a speed irregular of the other speeds of left lanes, they are required to change their pace at different times.
Hence, the drivers driving at slower speed in the left lane is considered to violate the traffic laws.
