Can Radar Speed Signs Give Tickets?

Radar speed signs are typically used by police or highway authorities to warn drivers of their speed and encourage them to slow down. The sign itself is a large box with a radar gun inside of it, which detects the speed at which vehicles are traveling past it. If you’re going faster than the posted speed limit, then you’ll be issued a ticket for speeding.

The reason why radar speed signs can give tickets is that they have been calibrated to detect only speeds that are above the posted limit. So if you go over 35 mph on a road where the speed limit is 25 mph, then your vehicle will trigger the radar gun and receive a ticket for speeding within minutes of passing by the sign.

How does it work?

Radar speed signs work by sending out radio waves that bounce off cars as they pass by them at high speeds. These radio waves are then converted into digital signals which can be processed by computer software in order to determine how fast each vehicle was traveling before reaching a certain point where there might be a camera or officer waiting for them at this location if law enforcement officials want them arrested for speeding up too much during their commute home from work every day.

What are radar speed signs?

Radar speed signs are devices that use radar to measure the speed of passing vehicles. These devices are often used in school zones and on highways, and they emit a warning sound when they detect that a vehicle is speeding.

How much do they cost?

Radar speed signs can range from $100 to $1,000 or more depending on their size, their accuracy, and other factors. The size of your sign will also determine how much it costs: for example, a smaller sign will cost less than a larger one.

Are they safe to use?

Radar speed signs are safe and legal to use. They work by using radio waves to detect the speed of passing vehicles, so there’s no need for a police officer to be present when you’re using them. They can also be used on private property or in areas where there is no law prohibiting them.

What is an issue with radar speed signs?

An issue with radar speed signs is that they can give tickets to people who are not speeding. If a radar speed sign is not calibrated correctly, it will show speeds that are higher than they actually are.

If a car is going 50 mph but the radar speed sign says 55 mph, then the driver will get a ticket for going too fast. The driver could contest this ticket in court and win because the radar speed sign was inaccurate.


Radar speed signs are often used by police officers to catch and ticket drivers who are speeding. The signs are relatively inexpensive, easy to use, and effective at helping officers catch speeding drivers. However, radar speed signs can also be used to issue tickets for other offenses, like running a red light or rolling through a stop sign.

If you have been issued a ticket after having been caught by radar speed signs, it is important that you speak with an attorney about your options.
