A BLIND mother from St Neots who planned to drive eight miles for charity could have her attempt halted unless she can get some insurance. Martine Brooks, 56, who works as a teaching assistant at St Neots Community College, hoped to drive the eight miles with a navigator at her side and raise money for the Guide Dogs for the Blind Association. For the past year she has been having driving lessons in a car park and on a disused airfield. However, her plans to take to the open road on the new - and empty - Great Barford bypass with the Mayor of Bedford, Frank Branston, may have to be rethought because of insurance problems. Martine, who has been blind for 25 years, said the plans are now uncertain as the Highways Agency wants her insuruers to be responsible for any damage caused during the event. The Guide Dogs for the Blind Association said it would insure Martine but could not agree to the Highways Agency's terms and conditions.
