The entire town of Palmer is a speed trap. Their sole source of revenue is I-45. Traps include I-45 SB at MM 260 where they sit in a church parking lot or just past the overpass. Likewise, I-45 NB at MM 260 they sit either on the entrance ramp or just past the overpass around the curve on the downward slope. Again, this entire town is a speed trap. Set your cruise and do not speed at all through the following cities south of Dallas; Hutchins, Wilmer, Ferris, Palmer. Palmer is notoriously aggressive. I drive that corridor regularly and it is not unlikely for Palmer to have 3 cars on that 12 mile stretch. Shut Palmer down. Don’t speed; the limit in Palmer is 65 mph and 60 mph in Dallas county, just north of Ferris. You will get caught.
