Caught Speeding by Laser Gun? How to Contest a Laser Speeding Ticket

How to beat LIDAR / Laser gun speeding tickets, and how they are different from radar gun-based speeding tickets

You need to understand the difference between laser (LIDAR, or ALSM) and radar if you want to know how to beat a laser speeding ticket. Lidar stands for light detection and ranging. Radar stands for radio detection and ranging. Lidar measures the vehicle's speed by calculating the changing time it takes to catch sight of reflecting pulses of light over a certain time period. Radar measures the speed by calculating the Doppler shift.

The effectiveness of the laser gun is determined by factors such as whether there is a license plate mounted at the front of the vehicle; surface area of the lights on the car; the amount of chrome areas on the vehicle; shape of the vehicle; and the colour of the vehicle. These points are important because it can help you to know how to beat a laser speeding ticket.

It is difficult to detect the use of laser speed equipment in advance, as it is a highly focused laser beam that leaves very little scatter. Your vehicle can't be mistaken for another vehicle. It can also be used over a large distance, which makes it even more difficult to spot. That is why you need to know how to beat a laser speeding ticket.

There are other ways in how to beat a laser speeding ticket such as the use of special paints and laser jammers, but they are not legal on all the states. Focus on preventative measures such as being alert. Check the rear view mirrors every eight to ten seconds. Watch the side of the car and keep enough open space around the vehicle to easily spot a patrol car.


You also need to know how to beat a laser speeding ticket when you are caught. The first few steps are the same as in any other traffic violation. Pull over, switch of the engine, roll the window down and don't make any sudden moves. The officer will ask you whether you know why he pulled you over. Always answer no. You can request an oral or written warning. Keep quiet if it is declined.

You need to know how to beat a laser speeding ticket if you decide to contest it in court. The object is to put the officer and the speeding equipment on trial. Create doubt by asking the following questions:

  •  Ask what the position of the laser gun was in relation to the sun and other bright lights, because laser uses infrared light and doesn't work well when aimed at the sun or other bright light.
  • When was it calibrated on the day of the violation?
  • Ask why, if the officer refused to demonstrate the calibration at the day of the violation.
  • Ask questions about the colour of your clothes, vehicle characteristics and traffic conditions in order to show that the officer doesn't remember the incident.
  • Ask the officer about the laws in the area to establish whether he indeed knows all the rules and regulations.
  • Question the officer about the operating procedure of the laser unit. Focus on any mistakes that he might have made.
  • Question the officer's hand stability because a slight movement in the arm can produce an incorrect reading, unless he made a cross reference with a stopwatch or radar to check the accuracy of the reading.
  • Ask questions about the officer's training to establish whether he received adequate training to operate the unit.

These are just a few questions you can ask to create doubt about the accuracy of the reading and the equipment. It is however important to prepare well for your court appearance. Follow the guidelines on how to beat a laser speeding ticket and do your research on other aspects such as what to do when you get pulled over and the plea process.

I went to court today in Mount Gilead, OH, and got the laser gun evidence dismissed in my trial because THE STATE OF OHIO DOES NOT RECOGNIZE JUDICIAL NOTICE FOR LASER DEVICES. Now the judge says that he is using the unaided visual testimony of the officer because he has given out over 500 tickets and they considered his testimony as an expert witness. I noticed house bill 86 in supreme court in Ohio against the unaided visual testimony of an officer, the case has been put in pending status due to this law. The judge said that since the law had not taken effect on August 25, 2011, the day of my citation he had to find me guilty, Can this be right? I thought it was the day of court you are being tried not the date of the citation, then I noted that court was TODAY not August 25, 2011, and then he said, if this law took effect on sept 30, 2011 he will consider dismissal but he had to make sure. Does anyone know if this house bill 86 has passed on Sept 30,2011??? please send me a link
