5 minHow to use road signage
Work-zone signage goes up in order: first the advance warning, then the taper with cones or drums that moves traffic out of the lane, then the closure around the work area and finally the end-of-work sign; it comes down in reverse order. SIMAQ has 28″ (71 cm) cones, 91 cm channelizer drums, 115 cm delineator posts, barrier tape, mesh, speed bumps and reflective vests. The faster the road, the longer the warning distance.
Also called: traffic cones, channelizer drums, delineators, speed bumps
Signage protects the crew and traffic, and keeps you compliant. Visibility, advance warning distance and an orderly closure are everything.
- 01
Warn ahead of the work
Place the warning sign far enough ahead for the driver to react in time.
- 02
Channel with cones or drums
Build the taper with evenly spaced cones or drums, steering traffic out of the zone.
- 03
Close the perimeter
Bound the work area with barrier tape, mesh and delineator posts. Visible by day and night.
- 04
Kit out the crew
Reflective vests on. Where speed must drop, a speed-bump reducer.
- 05
Remove in reverse order
When done, pick up signage from the work back to the start, so the crew is never left exposed.
Do this
- More advance warning the faster the road.
- Clean reflective material in good condition.
- Ballast cones and posts against vehicle wind.
Avoid this
- Don't start work before the signage is set.
- Don't leave fallen cones or broken tape: it confuses drivers.
- Don't remove signs with the crew still on the road.
Safety
- High-visibility reflective vest, always.
- Work facing traffic when possible.
- A flagger on high-traffic roads.

What people ask about road signage
Cone or channelizer drum: which one?
A short job on a low-speed street → cones. A fast road, night work or a multi-day job → channelizer drums, which are more visible and have a weighted base.
How far ahead does the warning sign go?
It depends on the road speed: the faster the road, the farther ahead, so drivers have time to brake. The exact distance is set by each country's traffic authority; the guide on signing a roadwork front lists the minimum kit.
In what order does signage come down?
The reverse of how it went up: from the work zone back toward the first warning sign, so the crew is never left exposed.
What's the most common signage mistake?
Starting work before the closure is finished, or leaving cones knocked over and tape broken. An incomplete closure confuses drivers right where the crew is.
Which reflective vest for roadwork?
A high-visibility vest with reflective stripes, worn the whole time you're on the road. SIMAQ has reflective mesh vests in cyan and orange.
