Getting a speeding ticket can ruin your day, but there are some situations in which you could potentially fight the ticket in court and win. You should never just pay for the ticket without considering your options.
According to FindLaw, you may have an easier time defending against a ticket occurring in a presumed speed limit area than one for an absolute speed limit violation.
Presumed speed limit
A presumed speed limit is one not posted on the road but rather set by general traffic laws. In most cases, you would get a ticket for a presumed speed limit if an officer feels you are driving at a speed unsafe for road conditions. For example, on wet roadways, the general rule is to reduce your speed under the posted limit to avoid hydroplaning or sliding.
In this case, you can either defend yourself by saying you were not exceeding the speed limit or your driving was safe despite the conditions. Evidence you can use is the speed of traffic around you or the road conditions at the time.
Posted speed limit
Posted speed limits are those on signs. They tell you exactly what the maximum speed is you can go on the road. If you drive faster than the limit, an officer can ticket you for speeding.
A potential defense in this situation would be to challenge the officer’s assessment of your speed by proving the tools used were defective or the officer mistook your vehicle for another one on the road. You can also show the court there was an emergency situation that justified your speed.
