Question 1 of 23

Match the description to the correct indicator

These markings identify the locations on a taxiway where an aircraft or vehicle is supposed to stop when it does not have clearance to proceed onto or cross the runway. These markings are installed on runways only if the runway is normally used by Air Traffic Control for “land and, hold short” operations or taxiing operations and have operational significance only for those two types of operations. The solid lines are on the side where the aircraft is to hold and the dashed lines are on the side toward the runway.
