Night Work Zone: SLOW Paddle, Temporary 35 Limit, and Two Sets of Lines

At 9:15 p.m. in October you are northbound on a two-lane road in Sussex County, Delaware, posted 50 mph, where a resurfacing crew is working under temporary traffic control. The signs arrive in sequence: an orange diamond reading ROAD WORK AHEAD; an orange rectangle reading ONE LANE ROAD 1,000 FT; an orange diamond with a flagger symbol; and a temporary black-on-white SPEED LIMIT 35 sign with an orange FINES DOUBLE placard beneath it. At the taper, orange-and-white drums and cones channel your lane left across the old centerline. The faded white edge line and an old yellow centerline are still visible to the right of the new path, and a fresh temporary yellow line has been laid to your left. About 100 feet past the taper, a flagger faces you holding a paddle showing SLOW, and a pilot car waits beyond him with its headlights on. The pavement is wet from the crew's water truck, and no workers are visible on foot anywhere in the zone.

1. What does the SLOW paddle require of you right now, and how does it differ from STOP?

Read the worked answer

A flagger's paddle is a traffic control device, and in a temporary traffic control zone the flagger's directions take precedence over the posted signs, the pavement markings, and even a signal, because the flagger can see conditions the signs cannot.

  • SLOW means proceed, but at a reduced speed, in your lane, with your foot covering the brake and your eyes on the lane ahead. You do not stop and wait; you continue carefully, prepared to stop if a worker, truck, or the pilot car requires it. Do not accelerate past the flagger to 'make up time.'
  • STOP means come to a complete stop and remain stopped until the paddle is turned to SLOW (or the flagger waves you on). Creeping forward while the paddle still reads STOP is a violation and is how flaggers get hit.

In this zone the SLOW is a signal to expect the unexpected: the pilot car ahead, equipment backing out of the closed lane, or a sudden narrowing. Because it is night and the surface is wet from the water truck, your reduced speed should be well under the temporary limit, especially as you approach the taper and the pilot car.

2. Which speed limit is legally in force in this zone, and how should the FINES DOUBLE placard change your behavior?

Read the worked answer

The temporary SPEED LIMIT 35 sign governs. It is a black-on-white regulatory sign installed as part of the temporary traffic control plan; when a work zone speed limit is posted, that posted number is the enforceable limit for the zone, and the permanent 50 mph sign no longer applies within it. Orange devices (drums, cones, arrow panels) guide you and warn you; they do not by themselves set the limit - the white regulatory sign does.

The orange FINES DOUBLE placard is a warning that penalties for moving violations - speeding above all - are enhanced in the work zone. Two practical consequences:

  • The absence of visible workers does not make the limit optional. At 9:15 p.m. the crew may be working behind equipment or just out of your headlights, and the posted limit is what is enforced.
  • The absence of a patrol car does not make it optional either. Assume enforcement, and note that stopping distance on the water-slicked pavement is longer than the 35 mph figure assumes on a dry road.

Treat 35 as a ceiling, and slow further where the taper, the flagger, and the pilot car are.

3. Two sets of lane lines are visible and the pavement is wet. Which markings do you follow, and what is your path through the zone?

Read the worked answer

Follow the temporary markings and the channelizing devices, not the old lines. In a resurfacing zone the permanent markings are obsolete until the new surface is striped; the fresh yellow line and the line of orange-and-white drums define the travel path, and the old white edge line and centerline to your right are to be disregarded. Drifting back toward the old alignment puts you in the closed lane, which may hold milling equipment, a paver, or a drop-off at the edge of the milled surface.

Path and technique:

  1. Slow before the taper, not inside it, and move left early and smoothly into the temporary lane.
  2. Hold a steady position just right of the new temporary yellow line, using the drums as your guide at night.
  3. Do not straddle the temporary line into the closed lane for any reason, and do not pass the pilot car - it exists to keep you behind the lead vehicle through the one-lane section.
  4. On the wet surface, increase following distance behind the pilot car and avoid sudden braking or steering; be ready for it to stop without warning.

If the markings are genuinely contradictory - for example, an arrow panel directing traffic into what looks like a closed lane - obey the flagger or the arrow panel, which override static markings in an active zone.
