Concerned residents in Horncastle are calling for restrictions to be placed on lorries travelling through the town centre.
They say some HGVs are too large for the narrow roads, particularly near to the junction of High Street and North Street - and on West Street.
Others claim lorries are causing obstructions by parking on yellow lines at busy times of the day.
Andrea Parker said she was worried about lorries on North Street when she walked her grandchildren to school.
She said: “They thunder passed. The back-draft they cause almost blows you off your feet.
“It’s not safe - especially near the bollard near the High Street. I’ve even seen lorries mount the pavement so they can pass each other at the same time.”
Mrs Parker was backed by other parents.
One, who did not want to be named, said: “The lorries are come hurtling down North Street and it can by scary, especially for children.
“It (the town centre) should be pedestrianised. It is dangerous now.”
A HGV was involved in a fatal collision with a pedestrian in the Bull Ring earlier this month.
