Mascoutah, Illinois Speed Traps
Rt. 4 south of I-64 is moderately patrolled with radar. You will get caught speeding on this road. Cars sometimes hide, other times patrol with moving radar.
Heavy patrol along Hwy 161 one mile either side of Hwy 4. Speed limit is not restrictive but patrol cars are well hidden so you will get caught speeding on this highway. They will particularly hide behind a rockpile east of Hwy 4 where the patrol car is not visible to eastbound drivers.
