HB 2235 Arizona House · 57th Legislature - First Regular Session

signs; lane use; civil penalty

HB 2235 requires Arizona road authorities to install specific signs on multi-lane highways directing slower-moving traffic to stay in lanes other than the farthest left lane. The signs must display "left lane for passing only, slow TRAFFIC keep right" alongside a "$500 fine" notice. The law mandates that drivers traveling slower than normal traffic must use the rightmost lane (or stay near the right curb), with a $500 civil penalty for violations. This directly affects all drivers on Arizona highways with two or more lanes traveling in the same direction.

MODERATE

This bill significantly narrows the scope of a traffic sign requirement and reduces the associated fine amount. Originally, the law required signs on all highways with two or more lanes in the same direction to direct slower traffic to the right. The House Engrossed version limits this requirement to only Interstate 8, Interstate 10, and Interstate 40. Additionally, the civil penalty for violating the slow traffic rule was reduced from $500 to $200.

Scope change

The bill's scope was narrowed from applying to all highways with two or more lanes in the same direction to only applying to Interstate 8, Interstate 10, and Interstate 40.

REQUIREMENT

Sign placement requirements were limited from all highways with two or more lanes to only Interstate 8, Interstate 10, and Interstate 40.

Sign specifications were updated to include a minimum size of 48 inches in height and 48 inches in width.

The requirement for a smaller accompanying sign with the fine amount was changed to allow either an accompanying sign or a warning printed directly on the main sign.

ENFORCEMENT

The civil penalty for violating the slow traffic rule was reduced from $500 to $200.
