On a motorway exit approach, each bar represents about 100 yards.✓پاسخ درست
Motorway countdown bars divide any remaining distance into three equal parts regardless of length.
Level-crossing countdown signs divide the distance from the advance warning sign to the stop line into three equal parts.✓پاسخ درست
Each level-crossing bar always represents exactly 100 yards.
توضیح
On a motorway exit approach, each countdown bar represents about 100 yards to the start of the deceleration lane. At a level crossing, the three signs divide the actual interval into equal parts, so one bar has no fixed 100-yard meaning there.
