§ Mr. FlynnTo ask the Secretary of State for Transport what effect on road accident figures was recorded following the introduction of speed calming humps on the M4 approach to the Wye river bridge.
§ Mr. Kenneth CarlisleThese rumble strips, which were not humps, were installed as part of a comprehensive scheme of traffic management during the strengthening and resurfacing work on the Severn crossing. It is not possible to say what effect they alone had on the accident rate.
