Ten days ago whilst travelling down the A11, south of Newmarket, in my Citroen Berlingo I hit one of several very deep holes in the centre of the dual carriageway. All power ceased, hazard lights operated and I was left to cruise onto the verge. After a long and extremely cold wait, an agent of the AA thankfully arrived and discovered that the very hard bump had operated the vehicle's fuel inertia switch. We proceeded homeward but could hear an ominous clunk when turning at low speeds. On investigation I discovered that the front off side suspension spring had fractured. I have had this replaced at a cost of £156. Can I claim against the Highways Agency? Neither passenger nor myself noticed any warning signs on this fast and busy road.
