Solar LED Signs for Road Works Zones
LED road works signs are solar powered illuminated signs that warn drivers in advance of resurfacing, excavation and utility works on the road. Work zones are often temporary and far from a power supply, so cable-free solar signs are quick to set up, while flashing LEDs improve visibility at night and in poor weather.
Work Zone Signs
- Warning signs: Road works ahead, caution, road narrows on the left and right, two-way traffic.
- Lane management: Lane shift left to right and right to left, keep right, keep left, pass either side, turn right and turn left only.
- Temporary speed limits: 20, 30, 50, 60, 70, 90 and 100 km/h signs.
- Prohibition signs: No overtaking, no entry and stop signs.
Signing a Work Zone
Turkish traffic regulations require construction, maintenance and repair zones to be signed according to the standard layouts set by the General Directorate of Highways (KGM). In practice, drivers first see a road works warning, then a reduced speed limit, and are guided through the safe route with lane shift and road narrows signs. Using LED signs together with traffic cones, water-filled barriers and solar flashers makes the boundaries of the work zone clearer.

Frequently Asked Questions
Which signs are needed for road works? Typically a road works ahead warning, a temporary speed limit, a road narrows or lane shift sign and an end-of-works sign; the exact layout depends on the road type and scope of work.
Can the signs be moved? As they are solar powered there is no cable to disconnect, so they can be moved with their post or stand as the work zone progresses.
Are LED road works signs visible at night? Yes, flashing LEDs make the sign visible from a distance at night and in bad weather, while the sign face carries its meaning by day.
