Los Angeles road and freeway signage does not promote awareness of Slow Traffic Keep Right practices. Signs on freeways and major thoroughfares saying "Slow Traffic Keep Right" will make more motorists consider staying right when driving at slower speeds.

Slow traffic in fast lines is a major cause of traffic congestion in Los Angeles. Changing lanes frequently causes traffic to slow or sometimes halt, resulting in increased congestion. Keeping slow traffic to the right and out of the fast lane will reduce lane changes and prevent freeway congestion and in daily commutes.

Many drivers in LA are unaware of best freeway driving practices and do not not know how driving slowly in fast lanes can impact traffic. "Slow Traffic Keep Right" signs will encourage motorists to drive in a way that reduces frequent lane changes, road rage and traffic congestion.
