Sample question from test 9
signals-markings
Why are signs, signals, and highway markings used together?
- To control traffic and make safe driving easier
- To replace every roadway inspection
- To make passing legal in every lane
- To provide fuel to every vehicle
Answer: To control traffic and make safe driving easier. Signs, signals, and pavement markings work as a coordinated traffic-control system. They regulate movement, warn about conditions, show where to travel, and make roadway decisions easier to understand. The choices about inspections, universal passing, and fuel describe unrelated subjects rather than the purpose of traffic-control devices. Read the device in front of you, compare it with lane markings and nearby signals, and follow the combined message. A driver who notices only one element can miss a turn restriction, warning, or required stopping action.
