7.10 Care should be taken to ensure that vehicles of the maximum length permitted by the Construction and Use Regulations will be able to pass safely under the bridge. This is particularly important where the road dips or hogs sharply or is on a curving alignment under the bridge. Changes in gradient might affect the headroom, e.g. the effective clearance will be reduced for a long wheel base vehicle spanning a dip. Where the road passing under a structure is on a sag curve, the headroom should be measured along the carriageway over a 25 m chord.
