Officials in Arizona are considering a new method to crack down on speeding by installing speed-limiting devices that impact how fast the car can actually go.
In Arizona, excessive speeding is the second leading cause of road fatalities, after driving under the influence.
Currently, those who are caught speeding face fines and the risk of losing their license.
But now the state is considering an alternative, which would allow offenders to continue driving with speed-limiting technology installed in their cars.

The devices work with any car and prevent it from going over the speed limit
State Representative Quang Nguyen of Yavapai County has pushed for legislation that would allow judges to mandate Intelligent Speed Assistance (ISA) devices be fitted onto offenders’ cars.
The smart technology uses cellular or GPS signals that can determine where the car is and how fast it is going, so it can establish if the driver is sticking to the speed limit in that location.
If the driver tries to go over the imposed speed limit, the device kicks in and will stop acceleration.
“It’s essentially a dead pedal. You can floor the car, and the vehicle just won’t accelerate beyond what the posted limit is,” Steer Safe Partnership’s Toby Taylor told AZ Family.
The devices work on any car and are activated automatically without the driver needing to do anything.
And, if the driver did try to tamper with the device, it sends out a notification to the authorities.
State Rep Nguyen told AZ Family that the speed-limited technology would allow those who have been caught speeding to continue working and being ‘productive’.
“Instead of being punished and losing the ability to keep your home, keep your job, drive to the grocery store, or take the kids to school, you now have an opportunity to have this product installed in your car, and now you can go to work and be productive again,” Nguyen said.

Arizona isn’t the only place considering the speed-limiting devices
Arizona isn’t the first place to consider introducing speed-limiting devices.
New York Governor Kathy Hochul has recently proposed a pilot scheme, which would see ‘drivers with a documented pattern of flouting speeding laws and putting New Yorkers at risk’ having Intelligent Speed Assistance devices installed in their vehicles.
Hochul said once the pilot program is finished, other communities in the area may want to implement it.
Meanwhile, Virginia and Washington State have both already introduced laws that allows speed-limiting tech to be fitted in offenders’ cars.
In Virginai, this goes into action in July of this year, while officials in Washington have said it will take effect in January 2029.
