How Revising the ‘Keep Right’ Law Can Prevent Tragedies

A proposed legislative change, known as HB2235, aims to address frustrations caused by slow drivers in Arizona’s left lanes. This bill would mandate that vehicles traveling below the normal speed limit on multi-lane roads keep to the right. Violators of this law could face fines as high as $500, highlighting the seriousness of the proposal.
The amendment targets existing regulations under Arizona statute 28-721, and it includes provisions for municipalities to install signs on applicable highways. These signs will instruct drivers that the left lane is for passing only, reinforced by a warning of the potential fine. Personal injury attorney Marc Lamber emphasizes that this reform could significantly enhance safety on Arizona’s roads.
One critical aspect of the bill is its potential to reduce road rage. Slow-moving vehicles in the left lane can lead to heightened frustration for other drivers, often resulting in aggressive behaviors as they weave through traffic to overtake them. By ensuring that slower drivers stay in the right lane, overall traffic flow could be improved, lessening the chances of accidents related to sudden lane changes.
Moreover, traffic studies indicate that variations in speed contribute significantly to accident rates. The presence of a slow vehicle in the left lane increases the likelihood of sudden braking or risky maneuvers from faster drivers. By keeping slower drivers in the right lane, the proposed law seeks to create a more predictable driving environment, fostering safety for all road users.
Another notable benefit includes the potential reduction of traffic congestion. Slow-moving vehicles often cause bottlenecks, leading to frustrating delays. This legislative change aims to maintain smoother traffic patterns, improving commute times across the board.
Finally, the law could particularly benefit teen drivers, who are disproportionately involved in traffic accidents in Arizona. By promoting a more predictable traffic flow, the law might reduce the risks faced by young, inexperienced drivers, helping ensure safer driving conditions for them.
In summary, HB2235 represents a proactive approach to improving road safety and traffic management in Arizona. With expected reductions in accidents, congestion, and aggressive driving, this change could lead to marked improvements in the safety and experience of driving within the state.
