East Coast Truckers Charity petition to save convoy
Supporters of the East Coast Truckers Charity Convoy hope that a petition launched in June will safeguard the future of the event.
For 25 years the charity has taken disadvantaged and disabled children to Great Yarmouth and Pleasurewood Hills in Lowestoft for a day out.
But a change in legislation means that the police will no longer be able to close roads for the convoy.
The final convoy is scheduled to take place on 28 August.
Convoy director Rob Billman said: "By having the public pressure out there it gives everybody the backing of knowing how strong the public feeling is."
A police spokesperson said that they had worked in partnership with the organisers and other agencies to offer advice and support on running this year's event safely.
"Orders to close roads have been obtained from the County Council as the police have no powers to close roads for planned events.
"Police motorcyclists will be accompanying the convoy and the organisers have taken steps to ensure all the children can have a safe, fun and memorable day out."
More than 100 lorries took part in last year's event and supporters of the charity started an online petition, with market employees in Great Yarmouth also collecting signatures.
It is hoped that the petition will keep the issue in the public eye and it will eventually be sent to Downing Street.
The police say they will continue to work with the organisers to see if there is an alternative way that the event can continue.
