Warning signs tell you what's ahead, work zone signs tell you how the road is changing, and regulatory signs tell you what you must do. Flaggers in work zones carry the same authority as a regulatory sign.

Know the rule

Warning signs cover road conditions needing caution and specific hazards, such as deer crossings, railroad crossings, school crossings or curves.

Know the rule

Road work signs are orange diamonds warning of lane closings, lane shifts, flaggers, uneven pavement and detours. Reduced speed limit signs are posted alongside them, and all traffic fines are doubled in work zones.

Reacting to road work signs

  • Control your following distance and reaction time; read the signs and follow directions
  • Be ready to slow down or stop
  • Stay alert to moving construction machinery
  • Watch for workers on the road; flaggers may stop and release traffic

Know the rule

Two national truck-route signs are used in New Jersey: green marks routes and ramps where trucks are permitted (and routes to services and terminals); red marks where trucks are prohibited and the end of designated routes.

Handbook p. 218 ↗

Put it into practice

In a work zone, a flagger holds up a STOP paddle even though the lane ahead looks clear. Stop: the flagger's direction carries the same force as a regulatory sign.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
