Radar and the Walker Case

In the case of People v. Walker, 610 P.2d 496 (1980), the Supreme Court of Colorado determined that the trial court was required to take judicial notice of the scientific principles of the use of radar. Further, the trial court was required to determine whether the radar used was properly operated and whether it was accurate at the time it detected the defendant driver’s speed.

The Court found that the use of a single uncalibrated tuning was not sufficient evidence to support the speed alleged. The prosecutor was required to show that two (2) tuning forks were used or that one (1) tuning fork was used an calibrated for accuracy within one (1) year of the test to admit the radar evidence.

This case is important to motorists in Colorado who have decided to proceed to trial on their Colorado speeding ticket where radar was used. There are many different ways to challenge a speeding ticket in Colorado. Pursuing calibration problems is one possible challenge.

Client Reviews
"An excellent lawyer choice for my son who was charged with driving while his license was revoked. DMV had mistakenly sent (3) letters of revocation to the incorrect address, so I hired Monty to prove that my son never knew his license was revoked. Monty kept me informed at all times as to what was happening and what he doing to prove my son's innocence in this matter. We were to appear in court on 29 March 2012 and Monte informed us on 27 March 2012, that the case had been dismissed!!! Monte charged a fair, flat rate for what he did in this matter and should the need arise to hire a lawyer or to recommend a lawyer, I would not hesitate to give Monte's name.” Linda
"I consulted three other attorneys on my traffic offense in Colorado and none of them thought I could beat it. Then I consulted with Monte Robbins. He not only relieved my warrant without my presence in Colorado, but he got my habitual driving offense reduced to an infraction. I was up against the wall on this case but thanks to Monte miracles are possible. I have hired my share of attorneys and Monte Robbins has produced the best results for me yet. After being without my driving privileges for ten years I paid a small fine and am legal with a clean record. I Highly recommend this attorney." Steve
"I hired Monte J. Robbins to represent me. He gave 110% to my case never rushed me off the phone, quick to gather all information regarding my case. Monte is very knowledgeable and helped me out a lot. He kept me informed every step of the way through my case. I was always able to get a hold of him for any questions i had. The outcome of my case was way better then i had expected. Monte did a excellent job on my case and I would highly recommend him to anyone. Monte won my case and I am confident that he can do the same for anyone else." Jeremy
