Jason Gilliat, who lives on the A586 in St Michael's on Wyre with his wife and two young children, asked Michael Jack, MP for Fylde, to contact the council to highlight his concerns after becoming frustrated with speeding drivers and trucks that use the village as a shortcut.
In a response from Jo Turton, executive director for the environment, the council promised it would make the school signs more visible, and Mr Gilliat says he is pleased positive action is being taken.
But he is worried that the current railings will not protect children in the event of an accident.
Mr Gilliat said: "The council has agreed to mount the warning signs on yellow backgrounds and review their locations, and I applaud them for doing something.
"But the safety barriers are rusty - if you leaned on them they would probably fall over. It makes me cross that the council would be so dismissive about it."
In her response, Ms Turton wrote: "The existing barriers here are old but generally in a reasonable condition and therefore not in need of immediate attention.''
She added, however, that the railing would be assessed against new guidance to see whether it should be extended.
The issue of traffic in St Michael's was highlighted by the Courier earlier this year, when Mr Gilliat complained that HGVs using the A586 were causing a major problem for residents.
He claimed HGVs were causing traffic backlogs as they travelled over the bridge near the school, creating structural damage in houses along the road and discouraging parents from walking children to school.
But Ms Turton says there is nothing the council can do to stop the vehicles using the road.
She wrote: "The A586 is a primary distributor road and as such, restrictions on weight or width of vehicles should only be considered where there is a safety, structural or environmental reason and where a convenient alternative route exists.
"The accident record along the A586 between the A6 and A586 shows only one injury accident involving a HGV in the last five years.
"There are no problems with structures on this route. The number of HGVs on this principal road does not constitute an environmental nuisance in terms of noise, severance or air pollution. No convenient route exists other than the M55 motorway.''
Mr Gilliat is now hoping to introduce speed indicator signs to the village, and says he will campaign for a 20mph speed limit outside the school.
