STARTING August 1, a new driving law will crack down on anyone driving even one mile per hour under the posted speed limit.
Under this “no dawdling” legislation, motorists caught cruising just under the limit in the left lane face hefty fees.

Louisiana is rolling out the tough new left-lane rule, enforcing $150 fines that could go up to $350 for frequent offenders.
Persistently evading the rule may even lead to jail time, making the consequences especially serious for repeat violators.
Several states are coming out with stricter traffic rules starting August 1, with fines, tech enforcement, and new driver requirements.
Officials made clear that, according to the Louisiana law, the left lane is strictly for passing traffic, and lingering there at slower speeds disrupts flow and frustrates others on the road.
Dubbed the “clogged up” law by critics, it’s designed to minimize highway bottlenecks and reduce overtaking chaos on highways.
Supporters of the law say it encourages faster-moving vehicles to pass unhindered, lowering the risk of sudden lane changes or collisions.
Opponents, however, call the legislation overly harsh, questioning whether punishing someone for driving just a little under the limit is fair.
The measures apply expressly to highways with marked left lanes, not surface streets or local roads.
Some drivers warn on forums that enforcement could feel trivial—or even invasive—especially if used by overzealous cops.
Despite that, lawmakers insist the policy will promote smoother traffic flow and bolster overall highway safety.
Louisiana’s new rule joins a growing push in other states, like New York and South Carolina, where similar laws are gaining traction.
In New York, sitting in the left lane below normal traffic speed can warrant fines up to $150, license points, and insurance hikes.
South Carolina is also eyeing tougher penalties, proposing to lift fines from $25 all the way to $100 for slow driving in the passing lane.
Though the Louisiana measure is uniquely radical—jail time for going just 1 mph slow—the trend reflects increased legislative efforts to keep highways moving.
