Construction & Temporary Signs
Do Not Pass When Flashing Sign
Do not pass the work or pace vehicle displaying this sign while its lights are flashing.
What to Do
Stay behind the vehicle and follow its guidance through the controlled section.
A Detail to Remember
The WHEN FLASHING wording is part of the instruction, not decoration beneath the symbol.
Understanding Construction & Temporary Signs
Work zones can change the route, road surface and available lanes. Read the sequence of signs together and watch for traffic control people, workers and equipment beyond the first warning.
