The turnout law mentioned above has nothing to say about driving slowly in the left lane because it is limited to two lane roads. Vehicle Code 21656 says:
On a two-lane highway where pbutting is unsafe because of traffic in the opposite direction or other conditions, a slow-moving vehicle, including a pbuttenger vehicle, behind which five or more vehicles are formed in line, shall turn off the roadway at the nearest place designated as a turnout by signs erected by the authority having jurisdiction over the highway, or wherever sufficient area for a safe turnout exists, in order to permit the vehicles following it to proceed. As used in this section a slow-moving vehicle is one which is proceeding at a rate of speed less than the normal flow of traffic at the particular time and place.
Entering slowly from a left hand ramp might violate the "slower traffic keep right" law, Vehicle Code section 21654. If you want to know what to do about a ticket for that violation the answer is the same as the answer to this next one:
You argue your side to the judge and he decides whether you have overcome the presumption that being in a lane other than the right lane while driving slower than the normal speed of traffic is a violation.
One mile or at the tail end of the queue. Being at the tail end of the queue means keeping up with traffic.
Faced with a similar dilemma in Mbuttachusetts, exceed the speed limit or drive slowly in the fast lane, I asked and got an answer from the State Police: I should exceed the speed limit by up to 15 MPH if necessary to safely take a left exit.
