Speeding tickets are the most common driving violation, but they can still cause you problems just the same. If possible, it is best to get a speeding ticket attorney who can defend you so you do not end up with a negative mark on your driving record.

You may be able to argue the officer's perception of how fast you were going. 

It is not uncommon for an officer to use their own perception to charge you with speeding, and if they do, you may have a better chance of defending the speeding ticket in court. Perception can be skewed in some situations. For example, if visibility was low and the officer was sitting in their vehicle from a great distance, their perception of how fast you were going could be off. 

You may get by with stating you were driving fast out of necessity to do so. 

Say you had a family emergency; your kid had an accident at school, your wife is at the hospital having a baby, you have been injured and you're on the way to the hospital. These situations sometimes warrant driving faster than you normally would. Even though the proper thing to do is to call emergency services or call and get a police escort, sometimes, a judge will be more lenient with you if you were speeding with a reasonable cause behind your behavior. 

You may be able to prove speed-measurement equipment as inaccurate. 

If you know how fast you were traveling, but the speed measuring device stated you were going faster, there may be a way for you to prove you were following the speed limit. There are a few ways that this can happen and be effective. For instance, if you have a device in your vehicle that monitors driving habits that belongs to your insurance company, you may be able to retrieve that data and use it to prove the measurement was inaccurate. Or, if you can get surveillance footage from a local business, it may show you were not traveling so fast. 

You may be able to defend yourself due to faulty equipment in your vehicle. 

If your speedometer stated you were going the speed limit, but an officer measured your speed far faster, this is an instance of speeding that may not totally be your fault. The judge may find you not-guilty of speeding and recommend you to get your speedometer repaired.
