Louisiana drivers could face jail for driving just under 1mph below the speed limit under a new law.
From August 1 onwards, drivers in the Bayou State will have to navigate a whole new raft of regulations.
This will cover everything from phone usage to window tinting and insurance mandates.
But of particular note is a change to the rules regarding driving below the speed limit.

Louisiana drivers could go to jail if they drive 1mph below the speed limit
At first glance, the law does sound harsh.
And it is kind of is – but it’s not a sweeping across-the-board law.
This prohibition on going 1mph below the speed limit is only in effect when it comes to the left lane, aka the fast lane.

On a first offence, slow-pokes can expect a $150 fine, with an additional $100 added on for repeat violations.
Anyone doing it habitually could find themselves behind bars for 30 days.
The margin for error had previously been 10mph below the speed limit.
There are more regulations now on the books, regarding window tinting, phone usage, and insurance.
Window tinting will be tightened from 40 percent to 25 percent light transmission.

Uninsured drivers will be barred from claiming up to $100,000 in damages, regardless of fault.
However, violators of those rules will receive warnings up until January 1.
After that point, they’ll be receiving fines of $100 for violations – and $250 fines in school or construction zones.
Laws are tightening in states around the US
Around the US, laws are being tightened up regarding a whole host of driving offences.
In Florida, anybody who goes 50mph over the speed limit or at any speed over 100mph faces going to jail.

That law seems reasonable, but we have to admit – some laws in some states are a little peculiar.
In Indiana, for example, it’s illegal to sell a car on a Sunday.
And over in New Jersey, it’s the law that attendants pump people’s gas for them.
With 50 states, there’s bound to be some variation in the laws.
But the most important thing is that people stay safe on the roads, regardless of what jurisdiction they drive in.
