     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Referring now to  FIGS. 1-7 , the present invention features a novel traffic safety system  100 . The system  100  of the present invention resembles a police car or emergency vehicle and serves as a decoy. In some embodiments, when the system  100  is activated, the system  100  (e.g., lighting) causes the driver to slow down, e.g., until the driver realizes the system  100  is a decoy. In some embodiments, the system  100  of the present invention is supplemented with a speed detection system, for example a radar system or a laser system. The present invention is in no way limited to the uses described herein. For example, in some embodiments, one or more components of the system  100  (e.g., the display panel  110  and light component  270 ) are attached or used in combination with a speed monitoring trailer or permanent radar mounts. Example 1 describes the system  100  of the present invention used in combination with a speed monitoring trailer. 
     The system  100  of the present invention comprises a display panel  110  (e.g., a banner) having a front surface  115  and a top edge  113 . A picture is disposed on the front surface  115  of the display panel  110 . In some embodiments, the picture is a photo overlay. In some embodiments, the display panel  110  is constructed from a material comprising vinyl. In some embodiments, the picture is of a police car  117  with a roof  118  or other emergency vehicle with the roof  118  of the police car adjacent to the top edge  116 . The present invention is not limited to a police car. For example, in some embodiments, the picture is a word (e.g., “slow,” “school,” “hospital,” “work zone,” etc.) or other picture. In some embodiments, the display panel  110  appears three dimensional. In some embodiments, the display panel  110  further comprises reflectors. 
     The system  100  further comprises a base  210  on which the display panel  110  is mounted. The base  210  comprises a vertical shaft  220  having a first end  221  (e.g., top end) and a second end  222  (e.g., bottom end). 
     Extending from the second end  222  (or near the second end  222 ) is at least a first leg, a second leg, and a third leg. In some embodiments, a fourth leg also extends from the second end  222  of the vertical shaft  220 . The legs  230  are adapted to help stabilize the vertical shaft  220 , e.g., in an upright and vertical position as shown in  FIG. 1 . Each leg  230  has a shaft end  231  (attached to the vertical shaft  220 ) and a free end  232  that extends away from the shaft  220 . In some embodiments, the legs  230  are arranged symmetrically around the vertical shaft  220 . 
     In some embodiments, a ballast  240  (e.g., a concrete block) is disposed on the free end  232  of one or more of the legs  230 . In some embodiments, a first ballast  241 , a second ballast  242 , a third ballast  243 , and a fourth ballast  244  herein collectively referred to as a ballast  240  each comprises a groove  245  located on an underside of the ballast  240 . In some embodiments, each ballast  240  is located on a free end  232  of one of the legs  230 . In some embodiments, the free end ( 232 ) of each leg ( 230 ) fits into the groove  245 ) of the ballast ( 240 ) to hold the leg in place. The ballasts  240  help provide weight and stability to the legs  230  so that the system  100  can be secured in place and help prevent the system  100  from tipping, e.g., in high winds. In some embodiments, a handle  250  is disposed on one or more of the ballasts  240 . The handle  250  allows the ballasts  240  to be lifted and transported. In some embodiments, the ballasts  240  are removably attached to the legs  230 . For example, as shown in  FIG. 6 , the ballasts  240  may be removably attached to the legs  230  via a second attachment means. In some embodiments, the second attachment means comprises a strap mechanism (e.g., straps  290 ), a magnet mechanism, a clamp mechanism, a hook mechanism, a tie mechanism, the like, or a combination thereof. 
     In some embodiments, the ballast  240  weighs about 50 pounds. In some embodiments, the ballast  240  weights between about 20 to 30 pounds. In some embodiments, the ballast  240  weights between about 30 to 40 pounds. In some embodiments, the ballast  240  weights between about 40 to 50 pounds. In some embodiments, the ballast  240  weights between about 50 to 60 pounds. In some embodiments, the ballast  240  weights more than about 60 pounds. As used herein, the term “about” refers to plus or minus ten percent of the referenced number. For example, an embodiment wherein the ballast  240  weighs about 50 pounds includes a ballast  240  that weighs between 45 and 55 pounds. 
     Disposed on the first end  221  of the vertical shaft  220  is a frame  260  (e.g., solar panel frame). In some embodiments, the frame  260  is adapted to hold one or more solar panels  268 , which are disposed flat on the frame ( 260 ). Solar panels are well known to one of ordinary skill in the art.

     The disclosures of the following U.S. Patents are incorporated in their entirety by reference herein: U.S. Pat. Application No. 2009/0237271; U.S. Pat. Application No. 2008/0197668; U.S. Pat. No. 6,422,714. 
     EXAMPLE 1 
     Example 1 describes the combination of the system  100  of the present invention with a speed monitoring trailer. Example 1 serves only as an example and is not limiting in any way. 
     The system  100 , for example the display  110  and the light component  270 , is activated and used as described herein. A group of policemen are responsible for operating a speed monitoring trailer in a 55 mph zone. The policemen first detect and record the speed of the traffic in the area with the use of the display  110  and light component  270  of the system  100  of the present invention. The policemen detect that the average speed of the vehicles passing through the 55 mph zone is 53 mph. The policemen then detect and record the speed of the traffic in the same area without the use of the system  100  of the present invention. The policemen detect that the average speed of the vehicles passing through the 55 mph zone is 62 mph. 
     EXAMPLE 2 
     Example 2 describes alternative embodiments and alternative uses for the system  100  of the present invention. The present invention also features devices that appear to be police cars with no lighting or solar panels, for example a sign with a permanently mounted base similar to what some police departments use for various types of traffic control such as the radar speed displays that are common everywhere. The device may be a supplement to enhance the effectiveness of the equipment currently being used. An alternative version of the device may be fabricated so someone could hold it, such as a flagger on highway construction projects that would operate with a small lawn tractor battery that would have to be charged when taken back to a shop during non construction hours. Whenever a flagger could see oncoming traffic he/she could activate the emergency light bar to slow down traffic. An alternative version of this device may be a cutout (e.g., plywood) in the shape of and painted like a police car mounted to permanent posts located in areas where there is trouble with transient traffic. The transient traffic would see it and not realize it is a decoy and slow down inadvertently slowing down local traffic that is aware that it is a decoy. It could also be enhanced by attaching red and blue reflectors to resemble the emergency light bar especially at night when headlights are shining on it. The banner could also be painted in 3 dimensional to resemble a police car. The devise could also be fabricated with an inflatable balloon in the shape of a police car, similar to what car dealerships use as advertising.
