Additional Conditions on Legality of Radar Detectors in the US in 2019
It’s important to note that while the general use of laws for private vehicles in different U.S. states is easy to remember, there are other factors concerning the legality of radar detectors. Some of these factors that would affect whether or not a radar detector is legal to include military bases, commercial vehicles, and windshield mounting. Read on to know more details about these factors.
Is it illegal to have a radar detector if you work in a military base?
As you already know, using a radar detector is generally allowed. However, using it in a military base is strictly forbidden! This applies to all visible radar detectors (there are hidden radar detectors). If you work in a military base, or you are planning to enter into it, you must remove your radar detector.
A good thing is that an officer will ask for you to remove it, so you won’t be fined. Due to the fact all military bases have checkpoints, you cannot enter into a base with a radar detector. Remember that hiding a radar detector and entering the base is breaking the law.
Is it illegal to have a radar detector in a commercial vehicle?
Is it illegal to have a radar detector in a truck or a bus? It is strictly forbidden using a radar detector in all commercial vehicles that weigh 10.000 pounds or more. These drivers are treated as professional drivers, so different laws apply to them.
In this case, there are no exceptions. The laws about radar detectors in private passenger cars and small trucks are different, but even for private vehicles, there are some actions you are not allowed to do.
Is it illegal to have a radar detector in your car?
Unless you are the driver of a big truck or commercial vehicle (under the federal law), it is completely allowed to have a radar detector in your car. Radar jammers, unlike laser speed detectors, are illegal and therefore banned in your car, doesn’t matter where it’s mounted.
Is it illegal to have a radar detector mounted on your car windshield?
In most states installing a radar detector on a windshield is treated as breaking a law, due to the fact it affects the driver’s line of sight. Some states that are strict about mounting devices in the windshield include California and Minnesota. So, if you are planning to travel across different states, keeping your radar detector off the windshield is something you must do.
It is recommended to install it on your dash or the sun visor. Cops always see a radar detector on a windshield, so a ticket and violation might easily come your way. Good thing, there are radar detectors that are designed to be concealed, so a cop won’t even notice them.
Radar Jammer Laws
While a radar jammer is different from a radar detector, it is quite helpful to know the laws about it too. This is especially because the two devices are often used together to have security from speeding tickets. A radar jammer is a device designed to interfere with the police radars and prevent them from detecting your current speed.
So, is it illegal to have a radar detector and a radar jammer at the same time?
In general, only using the radar detector is usually allowed. On the other hand, using a radar jammer is strictly forbidden. Most drivers use both devices, due to the fact they are more effective when used together.
You should know that radar jammer has a certain effect on law enforcement equipment and on air traffic control (on radars air companies use). This means that they work in a completely different way than radar detectors.
Jammers are usually installed as hidden devices, so cops cannot see them. However, they will notice that they cannot determine your current speed! As a result, you will be checked for these devices. And if caught using radar jammers, you’ll likely end up with an expensive fine and also confiscation.
Radar jammers are forbidden in all states and unlawful under the federal law. Using radar jammers will result in an expensive fine and also confiscation. However, laser jammers are not prohibited.
For specific radar detector laws, 41 states allow their use, while ten states have state laws banning laser jammers: Texas, Utah, Virginia, Oklahoma, South Carolina, Minnesota, California, Illinois, Colorado, and Tennessee. Radar detectors are legal in those states excluding Virginia. Radar detectors are also prohibited for big trucks in some states like Illinois and New York.
Radar detectors are awesome driving gadgets to have, especially when you’re keen to avoid speeding violations. But it’s important that before you even choose and buy the perfect radar detector for your needs, you ask is it illegal to have a radar detector in your country or your state. The same goes for radar and laser jammers, too.
Specific rules including mounting of the device are important to research as well, especially when it might cost you bigger fines or even suspension of license. So make sure that a part of your radar detector hunt involves the legality surrounding it for you to fully enjoy its perks and benefits.
Now, after you know the radar detector laws, you should just check if it worths it:
