Speed trap is from Warren Barrett Drive on the south of US Hwy 61 several miles straight through to about 1/2 mile north of State Hwy 168 near Tom Boland Ford. It is patroled mainly by the Hannibal Police Department who see this strip as a revenue generator for the city and for themselves. Officers are paid overtime pay for just patroling this stretch of Hwy 61. Overanxious policemen who are quick to write tickets to anyone, locals and out of towners. Fines and court costs are doubling in order to generate more revenue for the city. Truckers especially beware. Repeated speeding truckers who run stop lights are especially in the spotlight for heavy fines. MO State Hwy Patrol and Marion County Sheriff’s Dept occasionally patrol the area too.
